Characteristics of the tree group that produces fruit at the tip of the branch Lychee belongs to the group of year-round green leafy trees, multi-use trees, both for fruit, shade and landscape. The trees in this group often have the phenomenon of fruiting every year, which means the year of fruiting, the year of no fruit, the year of little fruit, the year of many fruits. Longan and litchi are all fruit-bearing trees, …. That is, the branch from the fall of the previous year is the mother branch bearing fruit next year. If the branch is healthy and the cake is dull next spring, flowers will bloom on the top of the branch. If winter has budded spring leaves do not flower. Therefore, in order for the tree to produce many flowers next spring, it is necessary to prepare many branches from the previous autumn, the branches are old and strong. That depends first of all on the post-harvest care. Longan and litchi trees grow fruit after a year, after harvesting, the branches and leaves fall off, which is the period when the tree is most physically exhausted. From the research results of agricultural experts, after harvesting, the roots are the part that loses the most force, followed by leaves and branches. In order to produce normal fruit next year, folk care experience along with cutting branches, pruning the canopy must be “compensated” or “compensated” in the post-harvest period. The selection of fertilizers and fertilization techniques are very important in order to restore the health of the tree, ensure the recovery, growth and development after 5-6 months of fruiting to continue to produce fruit next season. After harvest, longan and litchi trees need to be cared for and “compensated” so that the next crop can still be productive. Photo: TL. Van Dien fertilizer – The perfect choice for longan and lychee Among the current fertilizers, in addition to organic fertilizers, only Van Dien fused phosphate fertilizer and Van Dien NPK multi-element fertilizer products can meet the above demand for longan and litchi. Easily digestible nutrients in Van Dien fused phosphate fertilizers include: P2O5 15-19%, MgO 15-18%, SiO2 24-32%, CaO 28-34%, and many other micronutrients such as Fe, Mn, Cu, Zn, Bo, Mo…. Multi-factor fertilizer NPK Van Dien 5.10.3 has the content of nutrients such as: N=5%; P2O5=10%; K2O=3%; S=2%; MgO=9%; CaO=15%; SiO2=14%. In addition, there are trace elements such as B, Mn, Zn, Cu, Co… that other fertilizers do not have. Recently, the multi-factor fertilizer products NPK Van Dien 6:12:3 or multi-factor fertilizers NPK Van Dien 10:7:3 are very good fertilizers for fruit trees, especially in the post-harvest stage. . Using Van Dien fused phosphorus products and Van Dien NPK multi-factor fertilizers helps to provide a balanced, complete, multi-, medium-, and micro-nutrients for longan, litchi to restore roots and branches and leaves. Photo: Vandienfmp.vn. Instructions for fertilizing longan and litchi in the post-harvest period This year’s lychee fruit season is very good, so it is necessary to increase efforts to take care of litchi early, while the longan trees bear fruit unevenly, even many trees do not bear fruit, so the care of this year’s longan must be specific to each tree. Non-flowering longan and litchi trees: The longan and litchi trees this year do not flower if this year is not well taken care of, next year will certainly be poor in harvest. To prepare for the fruiting season in 2022, with the trees that do not bear fruit this year, around June and July, corresponding to the annual fruit collection time, still cutting, pruning and weeding as every year. At the same time, apply deep fertilizer with 3-4 kg of composted organic fertilizer and 3-5kg of Van Dien fused phosphate fertilizer, in order to provide phosphorus and secondary and micronutrients, part to prepare and accumulate nutrients. for the next crop, the nutritional compensation for the recent overgrowth of leaves is too strong. The litchi trees, longan trees are bearing fruit: Immediately after collecting the fruit, it is necessary to immediately start weeding for the trees: Prune toothpicks, pests, overhanging branches, branches under the canopy … at the same time, fertilize the trees, hoe around the canopy and then fertilize. The amount of fertilizer for each root is about 5-10kg of composted organic fertilizer, 5-7kg of Van Dien fused phosphate fertilizer and 3-5kg of Van Dien NPK multi-element fertilizer (5:10:3, 10:7:3. ..). Mix well with the soil, spread it in the canal and fill 2/3 of the trenches, grass cabinets, and garbage to keep the stumps warm. If the soil is too dry, it needs to be watered to keep the roots moist. Based on the time of harvest and the health of the tree, it is necessary to affect the summer or autumn buds. The early fruit trees in June, July, after weeding and fertilizing will give summer buds. Fertilizing for the autumn fortune: Locusts are formed on the leaf axils of summer buds (for early-harvesting plants) or grow from the leaf axils of fruit branches with late-autumn plants. This is the fruit branch of the next year’s longan and litchi crop, so it is necessary to pay special attention to adjusting fertilizer so that the harvest ends before November every year. Apply fertilizer to promote autumn buds in September and October after the summer buds have matured (into the leaves), apply 2-3kg of multi-element fertilizer NPK Van Dien 10:7:3 in combination with felling, pruning and removing branches. pass) in the canopy. Apply fertilizer to promote the collection of 2-3kg of multi-element fertilizer NPK Van Dien 10:7:3 in combination with felling and pruning. Photo: Vadfco. Note, only fertilize the autumn buds for trees under 15 years old, showing signs of lack of fertilizer, poor growth (showing yellow-green leaves) or late fruit trees in August, September. The growth pattern of the tree and the yield of the harvested fruit with more or less fertilizer application. If the weather is dry, it must be combined with watering to help the plants recover quickly and develop early autumn buds. When the buds are collected evenly, it is necessary to spray insecticides to ensure that the buds come out evenly and abundantly, the young buds grow well and are strong enough to make fruiting branches next year. Usually on an old fruit branch, there are many new shoots. When the young branches have enough leaves, it is advisable to trim away the weak, weak branches, leaving only the strong, fat huts to keep as the mother branch for the next crop. In the winter months, do not water, fertilize, create all conditions for the tree to “barren”, inhibit the formation and development of winter buds. By applying Van Dien fused phosphate fertilizer and Van Dien NPK multi-factor fertilizer right after fruit collection to create many vigorous autumn branches, combined with inhibiting winter buds, spring when the weather is warm and humid, longan trees , the fabric begins to spring up. Only apply fertilizer to catch flowers for longan and litchi when flower sprouts appear in the axillary leaves of the branches, the amount of application is about 3-5kg of multi-factor fertilizer NPK Van Dien 10:7:3 or 10:10:3, buried. Seal the manure, then water it to stimulate the buds and flowers. Fused phosphate fertilizers and specialized multi-factor NPK fertilizer products for Van Dien at the same time provide a full and balanced supply of essential nutrients for longan and litchi trees, helping them to grow strong and resistant to external conditions. Under unfavorable circumstances, especially during the winter break, litchi trees balance growth with development, creating bountiful fruit seasons.

Over the years, farmers northern provinces selected multi-element fertilizer (DYT) NPK Van Dien specialized in fertilizing rice crops with outstanding efficiency, the product lines of DYT NPK Van Dien fertilizer have 13 nutritional components, the ratio of nutrients depends on Depending on the type of fertilizer used for priming or for top dressing. According to local custom and also due to market demand, rice variety structure In the northern mountainous provinces, it is quite abundant: in addition to cold rice varieties such as hybrid rice, short-term pure rice KD18. Vnr20… group of semi-photosensitive rice varieties such as U17, U19, or tall sticky rice varieties; In many places, special photosensitive rice varieties are planted such as Bao Thai, yellow flower sticky rice… (Dinh Hoa – Thai Nguyen area). These are high quality rice varieties, but the percentage of flat seeds is high and it is easy to fall if lack of phosphorus and other medium and micro nutrients. From the agronomic characteristics of rice transplanting, as well as nutritional requirements, specialized NPK fertilizer Van Dien provide nutrients for rice plants, from transplanting to the time of flower differentiation (Nutritional growth stage). The fertilizer product lines DYT NPK Van Dien have all 13 nutritional ingredients Research on physiology and nutrition of rice shows that: The life of rice plants can be divided into 2 growth stages: vegetative and vegetative. The vegetative growth stage was counted from the sowing rice to the female standing rice. Crop season, this period usually lasts about 30-35 days with short-term cold varieties; (In particular, the photosensitive rice varieties must wait for a “short day”, which is close to the Bach Lo period, before the rice changes to the vegetative stage). At this stage, the roots develop in the shallow soil layer (about 3-5cm) and in the direction of spreading according to the cover of the rice leaves, when the set of rice leaves covers the row, the rice roots are also woven into the field. this period rice focus on tillering, spreading leaves, spreading sheath to make false stems, so the most nutritional needs are protein, potassium and less phosphorus and other medium and micronutrients. DYT NPK fertilizer specializing in fertilizing rice has many different formulations such as: multi-factor fertilizer NPK ( 16 :5 :17) has a content of N 16%, P2O5 5%. K2O 17% Mg 5%, SiO2 7%, CaO 8%, S 2%, etc. Currently, many places people use NPK . formula 13:3:10 +TE. These are fertilizers with high nutritional content of nitrogen, helping rice plants to lay strong, grow leaves, and grow stems. The nutrient content of potassium is quite high in the fertilizer to promote moderate tillering. In addition to the balance of NPK substances according to the needs of rice plants at tillering stage, there are also enough medium and micronutrients to help rice plants grow healthy, hard rhizomes, good resistance to pests and unfavorable environment. The stage of vegetative growth was calculated from the time of differentiation of the stem to the maturity of the rice. The long-term rice varieties have the time to stand female, while the short-term rice varieties usually do not show the time when the rice is female, but the rice plants may still have tillering but have differentiated. The time of transition to the vegetative stage is counted from when the rice leaf set is more upright, the leaves are “equal to the head” or when the rice begins to harden and round the base. From here, a second layer of roots develops into the soil layers below; When the rice plant blooms, it is the time when the trunk reaches its greatest height, the roots also go down to the plow layer and reach the greatest “depth”. Providing enough nutrients at this stage helps the process of making poles, favorable flowering, good and durable leaves and large flowers, many seeds. In addition to the micronutrients, rice plants need a lot of phosphorus and NK balance to differentiate flower sprouts, especially high silicon content to help harden the root, stem, and stand the leaves to increase resistance to pests and sugar accumulation. flour. NPK fertilizer specialized in fertilizing rice has many different formulas such as: NPK NPK 6:12:3 or NPK 5:12:3 , 10:10:5, 10:7:3 or multi factor rice fertilizer 1 specializing in fertilizing rice with sufficient and balanced nutrients NPK and micronutrients necessary for rice plants in the growing and flowering stage. Multi-element fertilizer (DYT) NPK Van Dien specializes in fertilizing rice crops to help achieve outstanding efficiency Cultivating seasonal rice in the northern provinces with fertilizer DYT NPK Van Dien: Manuring : Depending on the foot of the field, rice variety and the amount of organic fertilizer, balance the amount of fertilizer in the crop; average about 15-20 kg / sao. High-legged fields, less rice transplanted, less fertilizer, low-lying fields, more acidic, more rice transplanted, more fertilized, especially Bao Thai rice fields, tall sticky rice trees.. need to give priority to lining fertilizer, can fertilize 20-25kg/pole. In order for the fertilizer to be mixed evenly and sent to the soil layers below, meeting the nutritional needs of the rice growing and flowering stage; manure should be spread evenly on the field before harrowing for transplanting or before the last harrowing turn; If you are worried about dehydration or loss of manure, you can spread manure right after the harrowing is completed, when the water is still cloudy and the mud is still loose. Do not apply fertilizer after the water is clear, the mud has settled. Because when the sludge is settled, the nutrients have been attached to the soil grain and sink, in the water at this time only the substances that cause acid and alum remain, which are toxic to the rice roots. Therefore, to settle the sludge, in the water for 1-2 days, remove the clear water and then sow. Dressing: .Based on the bottom of the field, the amount of NPK multi-factor fertilizer applied as a primer and the growth situation of each rice variety that fertilizes seasonal rice as follows: – Thickly transplanted rice fields, large transplanted fields, low-lying fields… Fertilize about 8-12 kg / pole. – The fields are fertile, high, or dehydrated. High yielding rice varieties need to be fertilized about 12-15kg/sao. -The swampy fields, Bao Thai rice fields, tall sticky rice, or other easy-to-fall rice varieties… reduce the amount of fertilizer, (you can even remove fertilizer) and should only fertilize when transplanting. 7-10 days. – Particularly, the foot of the field is high and rapid, the rice variety is hard-bodied, the fertilizer is applied twice: 60-70% of the fertilizer is applied when the rice is ready to burn, and the rest of the fertilizer is applied. To reduce fertilizer loss due to evaporation, leaching or leaching, etc., fertilizer should not be applied when it is hot and when the field is full of water. Fertilizer should be applied when it is cool and the field is dry.

Along with Dai Tu tea area, from 2005 up to now, Van Dien fused fertilizer and specialized multi-factor NPK fertilizer Van Dien have also been tested and gradually used for industrial crops in the northern mountainous provinces. . Through the process of using, Van Dien fertilizer has been bundled with production, has a brand and trust with people here. Although no additional lime is required, agricultural land is improved, reduced acidity and increased porosity, crops grow better, higher quality and help farmers reduce the amount of fertilizers and pesticides. diseases, protect the ecological environment, and at the same time reduce labor. Hoa Binh sugarcane growers choose Van Dien fertilizer because it helps to increase productivity, reduce pests and diseases and increase the quality of cane sugar. With white sugarcane, the tree is firm, not porous like when fertilizing with a lot of nitrogen, fresh water, not sour. Purple sugarcane color is smooth and dark purple, increasing the sweet and aromatic taste. When applying Van Dien fertilizer, purple sugarcane and white sugarcane all give long internodes, fat plants, blooming tops, bright green leaves, and hard plants. The Central Highlands has more than 1 million hectares planted with coffee, rubber and pepper trees, of which coffee accounts for nearly 70%, Sao rubber 20%, the rest is pepper. The soil is mainly red basalt and gray soil with thick, porous, well-drained cultivation layer, suitable for many crops, especially coffee, pepper and rubber. After liberation (1975), the Central Highlands’ land was strongly exploited, ethnic farmers here invested to intensively cultivate coffee, rubber, and pepper beyond the allowable limit to have the highest output, ten years. The crop grows well at the beginning, but gradually decreases in the following years due to the imbalance of nutrients in the soil. Due to the limited knowledge of gardeners, the massive use of chemical fertilizers leads to a decrease in yield, crop quality, and an increase in costs. From 1990 to 2013, Van Dien Fused Phosphate Company cooperated with scientists from the Central Highlands Agro-Forestry Science and Technology Institute to conduct many experiments to research and use Van Dien fertilizer for coffee plants. Coffee, pepper, rubber in the provinces of Kom Tum, Gia Lai, Dak Lak, Lam Dong… gave outstanding results. On red basalt soil, gray soil, the yield of 1kg of P2O5 in Van Dien fused phosphorus gave a bumper harvest of 31.6 – 33kg of green coffee, an increase of 11.2% compared to the control (other phosphate fertilizers). Especially on gray soil, the yield of 1kg of P2O5 in Van Dien fused phosphate fertilizer reached 31.7kg of green coffee, an increase of over 20% compared to other phosphate fertilizers, with pepper and rubber, Van Dien fused phosphate fertilizer. It also gives an increase in profit compared to other phosphate fertilizers from 8 to 15%. Especially, since 2010, a series of multi-factorial fertilization (DYT) experiments with Van Dien NPK for coffee, pepper and rubber were also carried out on red basalt and gray soils and gave very good results. different from other types of NPK. According to the new concept, clean agricultural production and organic agricultural products are not allowed to excessively use synthetic chemicals such as chemical fertilizers, plant protection drugs, growth stimulants, preservatives, and variable materials. genetic modification… but rather the use of manure, organic fertilizer, natural mineral fertilizer… is a technology to meet the balanced nutritional needs of plants, while maintaining and improving soil fertility, and protecting ecological environment, leaving no toxic residues in agricultural products, creating products of high quality, safe for users and bringing high economic efficiency to producers. Van Dien fertilizer completely meets the requirements of producing clean vegetables, safe vegetables, organic vegetables…: providing nutrients in each period according to the needs of plants. Vegetables and crops are fertilized with NPK multi-factor fertilizer – Van Dieu’s fused fertilizer in combination with nitrogen and potassium in appropriate proportions for each plant; not only bring high productivity, good quality of agricultural products, ensure safety for users; but also increase the resistance to pests, diseases, drought, cold and spill resistance, reduce the use of pesticides, protect the ecological environment. This is also the key to our country’s agricultural production, ensuring that crops grow well, are safe for the soil, products meet quality standards and confidently conquer the market.

Orange Can be grown in many places, but because the bran root system absorbs nutrients, it mainly grows on topsoil from a depth of 50cm or more, prefers loose, aerated soil but must ensure enough nutrition and good moisture. stable, so only some regions with specific conditions can effectively cultivate oranges. According to scientific calculations, an average of one ton of oranges is removed from the soil: 1.7kg N; 0.5kg P205; 3.2kg K and secondary and trace substances. The soil suitable for growing oranges has a thick, porous, well-drained cultivation layer, with alkaline pH from: 5.5 – 6.5. When the soil acidity is lower than 5.5, the roots will be toxic by Fe, Al, the plants are susceptible to lack of nutritional factors such as: Ca, Mg, P and Mo, the activity of soil microorganisms is also affected. reduced low. The nutrition trace elements such as Zn, Cu, Mn, Fe, B0, M0, C0…. Micronutrients also have the effect of improving the soil, helping to reduce the number of seeds, increase the flavor, beautify the fruit, contribute to increasing the yield and quality of oranges when harvested. Lack of trace elements makes the plant imbalanced in nutrition, prone to yellow mosaic disease, flower drop, young fruit drop, diseased plants and abnormal growth. Due to the above requirements for soil, nutrients and tree characteristics, many concentrated orange growing areas have chosen to use it Van Dien fertilizer n and gives very high efficiency. Lan Van Dien has a fairly high ratio of Calcium, Magnesium, and Silicon, so it has the effect of reducing acidity, gradually raising the pH of the soil, suitable for orange trees. The land for growing oranges is mainly grown on hills, gardens, and riverbanks where it is high and steep; easily washed out and lack of intermediate and trace substances. Lan Van Dien is a slow soluble phosphorus, only soluble in weak acid solutions secreted by the roots, where the plant needs to dissolve the fertilizer, so it is limited to being washed away. Besides Lan Van Dien It also adds essential nutrients and trace elements for plants. Produced from Van Dien fused phosphate fertilizer, specialized NPK multi-element fertilizers for oranges are different from some common NPK fertilizers, in addition to nitrogen, phosphorus, and potassium, there are also medium and micronutrients. Van Dien NPK provides 16 essential nutrients for plants with a high and balanced nutrient ratio NPK Van Dien provide enough 16 essential nutrients for plants with a high and balanced nutrient ratio. For oranges in the business period, the amount of fertilizer invested depends on the quality of the soil in the region, the age of the tree and the annual yield. In 1 year, in combination with rotten organic fertilizer, Van Dien fertilizer is divided into 4 fertilization periods: 1st: After harvesting the fruit. Apply a root of 10-15kg of organic fertilizer, 3-5kg of Van Dien phosphorus. Three times after applying with multi-factor fertilizer NPK Van Dien: 13;3:13 or 12-8-12, 12-12-17. Phase 2: Around March-April, after the physiological fruit drop. Oranges from 4 to 7 years old, apply a 1-1.5kg root; oranges from 8 – 11 years old, apply a 1.5 – 2kg root; Oranges over 11 years old, apply a root of 2.5 – 3kg. 3rd round: In June-July, fertilize fruit after stabilizing the number of fruits on the tree. Oranges from 4 – 7 years old, apply a root of 1.5 – 2kg; oranges from 8 – 11 years old, apply a root 1.5 – 2kg; Oranges over 11 years old, apply a root of 2.5 – 3kg. Phase 4: In September-October, 1 – 1.5 months before harvest, apply multi-factor fertilizer NPK 12:12:17 to limit the second physiological fruit drop and limit fruit cracking, especially weight gain. yield and fruit quality at harvest. Oranges from 4 to 7 years old fertilize a root 2 – 2.5kg; oranges from 8 – 11 years old, apply a root of 2.5 – 3kg; Oranges over 11 years old fertilize a root of 3.5 – 4kg. Van Dien fertilizer provides a full balance of all kinds of macronutrients, intermediate and micronutrients to satisfy the nutritional needs of orange trees throughout the crop year. Van Dien fertilizer helps orange trees grow healthy, balanced, green leaves, bright, thick leaves, less pests, high fruiting rate, large, uniform fruits, reduce fruit drop, help balls, Large, smooth, especially when ripe, the dark yellow skin is very attractive, high yield, increased sweetness, stronger flavor and longer shelf life. How to fertilize: * If, after harvesting the fruits of the previous crop, the incision was made and then fused with phosphate fertilizers and rotted organic fertilizers were applied, now apply fertilizer according to the old canal: spread fertilizer along the canal and then cover with soil, leaves cover the manure. * Can spread fertilizer according to the projection of the canopy back, about 50-60cm from the root, spread the fertilizer and then cover with soil, if it is dry, it must be watered; You can soak the manure to dissolve it and then mix it with water to irrigate.

The provincial Ha Tinh there are more than 7,000 ha of citrus trees, of which orange and pomelo trees account for nearly 90%. The most cultivated area for pomelo trees is in Phuc Trach, Huong Trach and Huong Do communes (Huong Khe district), while the orange area is mainly concentrated in Vu Quang district up to 2,500ha, Thuong Loc commune (Cam Loc district) is 240 ha.

Land for planting oranges and pomelo This area belongs to the group of red and yellow feralit soil and an area of ​​basalt soil formed on hilly or mountainous terrain interspersed with high mountains, very hot summer climate, on average 380C, cold winters and rainfall. Large, suitable for grapefruit, orange trees.

However, in the agronomy of pomelo and oranges, there are many limitations due to the unscientific use of fertilizers, farmers rarely invest in organic fertilizers, use too much acidic chemical fertilizers such as supe, phosphorus, nitrogen, etc. or types of fast-soluble NPK containing acid root for fertilization, intercropping legumes for land investment is limited, and in the rainy season, soil is very large.

As a perennial tree, pomelos and oranges in Ha Tinh lack nutrition and sour environment, thus reducing productivity, appearing harmful pests and diseases. Before 2010, the brand name of Phuc Thach pomelo and oranges in the market was faint. The area of ​​orange cultivation has narrowed, the gardeners’ income has decreased sharply … in order to restore the brand, regain productivity and quality, Ha Tinh province has focused on investing in building a fertilization process according to the VietGAP standards.

Understanding local needs and shortcomings in the use of fertilizers by farmers, Van Dien Fused Phosphate Joint Stock Company cooperates with Ha Tinh Gardening Association to deploy many models. using Van Dien fertilizer for pomelos, oranges and safe vegetables on the table in Huong Khe, Vu Quang, Duc Tho …

Trial on Van Dien fertilizer in pomelo production areas of Phuc Trach, Cam Khe May, Thuong Loc, Cam Bu Huong Son.

The experiment was conducted in a closed crop year 2010 on 1.5 ha of 15 year old grapefruit in Phuc Trach, together with 2.0 ha of 10 year old oranges in Khe May and Huong Son by using completely Van Dien fertilizer including Fused phosphate fertilizer and NPK multi-factor fertilizer is used specifically for citrus. Van Dien fertilizer divided fertilizer 4 times a year:

• Stage 1: Applying after harvesting, using 1.5 – 2.0 kg / root of Van Dien fused phosphate + multi-element of NPK 5.10.3, from 2- 4 kg + 15 kg of decomposed organic fertilizer /origin.

Phase 2: Applying flowers with the amount of fertilizer from 1.0 -1.5 kg / root of ĐYT NPK 12.5.10.

Stage 3: Applying after fruiting from 2.0 to 3.0 kg / root of health care NPK 12.8.12

• Phase 4 fertilizing 50 days before harvesting fruit from 1.5 -3.0 kg / root ĐYT NPK 12.7.20.

Grapefruit fertilized with Van Dien is more prominent than the control along with other NPK fertilizers in that: Bright green leaves, shiny leaf surface, thick leaves, smooth bark and branches, 50% reduction of harmful pests and diseases. high fruiting, fruit uniformity, concentrated ripening, beautiful peel color, less fruit drop, yield 1.8 times higher than control, sweet and fragrant quality characteristic of Phuc Trach grapefruit and famous Buu before. After only 10 years, farmers have liked the effectiveness of Van Dien Fertilizer

Mr. Nguyen Xuan Tinh – Chairman of the Gardening Association of Ha Tinh province said, “Since the introduction of Van Dien fertilizer, orange trees, grapefruit trees here are fully supplemented with nutrients, healthy plants, good growth and development. With high yield and quality, up to now, Ha Tinh province has thousands of hectares of citrus trees fertilized with Van Dien fertilizer ”.

Mr. Hoang Van Giam, Phuc Trach commune, Huong Khe district, said: “My family has 200 grapefruit roots 10 years old, in the last 6 years, I completely use Van Dien fertilizer, every year grapefruit has good season to sell. After fertilizing a healthy grapefruit tree, wrong flowering, large fruiting, uniformly large fruit, less drop, reducing pests, yield, high quality, Van Dien fertilizer contains much more nutrients than other types. Fertilizer is currently on the market, in Phuc Trach most people use Van Dien fertilizer.

Ms. Pham Thi Lanh, who has 500 oranges and is 13 years old, commented: “Van Dien fertilizer with good quality, competitive price, convenient supply, easy to use, high efficiency, great profit. More than 7 cases of oranges in the family completely use Van Dien fertilizer, the most difference is the color of the leaves, the shade is visible from a distance, dark green, after heavy rains, the trees are very few to drop fruit, the stools are good and durable. , good quality, high productivity, high quality, easy to consume, especially less using plant protection drugs, safe for users, protecting the environment ”.

In the Buu orange growing area in Son Mai, Son Thuy, Son Truong communes with more than 1,000 hectares, Mr. Ngo Xuan Hoa, Son Mai commune, cultivating 300 orange trees, shared: “The family has tested many fertilizers for orange trees, but Only Van Dien fertilizer is suitable and easy to use fertilizer. Van Dien fertilizer is more than other fertilizers, it is full of 13 types of nutrients to meet the needs of orange trees, so plants are healthy, less pests, high yield and quality ”.

Van Dien fertilizer helps plants to be healthy, less pests, high yield and quality

Bringing Van Dien Fertilizer back to people growing safe vegetables in Ha Tinh.

Recently, the demand for safe vegetables of consumers is very large, small farming methods, heavy using chemical fertilizers and pesticides have been replaced by more scientific farming methods. according to VietGAP standards, cultivating safe vegetables, clean vegetables, organic vegetables. The vegetable growing land in Ha Tinh is mostly on alluvial soils that are poor, humus and acidic, pH
