(VEN) - Rice grown in Thai Binh Province, oranges grown in Tuyen Quang Province’s Ham Yen District and coffee grown in the Central Highlands are among numerous kinds of Vietnamese farm produce that have carved out niches in both domestic and export markets. A similarity of these products is the use of fertilizers made by the Van Dien Fused Magnesium Phosphate Fertilizer Joint Stock Company (VADFCO) in cultivation.
Increasing plant value
Experts believe VADFCO’s products are a good choice to improve the quality of farm produce and promote sustainable agriculture. VADFCO’s fertilizer products consist of not only phosphate but also calcium, magnesium, silicon and seven micronutrients: zinc, iron, copper, boron, manganese, molybdenum and cobalt. These micronutrients account for 70 percent of VADFCO’s fertilizer content.
VADFCO’s fertilizer products are alkaline with the pH level ranging from 8-8.5. They are nontoxic and dissolve in the environment of exudations from the roots of plants. They cannot be swept away by rainwater. Van Dien fertilizers cannot dissolve in water and therefore do not facilitate the growth of mosses but provide phosphate and micronutrients for only cultivated crops.
Therefore, Van Dien fertilizers not only help increase crop yields and improve farm produce quality but also help maintain soil nutrient balance to facilitate effective farming.
A companion of farmers
Over the past many years, VADFCO’s fertilizer products have won the trust of farmers nationwide. The use of multi-element NPK fertilizers has proved to yield better results than normal phosphate fertilizers. Van Dien fertilizers have become a reliable companion of farmers in the Central Highlands, the mountainous areas in the north, the plains in the south and coastal areas.
In Tuyen Quang Province for example, farmers consider orange orchards a new “gold-mine”. The locality has nearly 8,000ha of orange orchards concentrated mostly in Ham Yen District. The climatic and soil conditions in Tuyen Quang are favorable for orange growth. In the past, until their access to VADFCO’s products, orange farmers in the province mostly used large volumes of single nutrient fertilizers and pesticides, leading to soil degradation and low fruit quality.
Orange farmers in Ham Yen District began to use Van Dien fertilizers in 2003 and created breakthroughs in fruit yield and quality. Initially, they used Van Dien fertilizers after harvesting the fruit in order to regenerate the roots of the trees and provide them with micronutrients throughout the cultivation process. In some orchards, Van Dien fertilizers were also used during the fruiting period to improve the quality of the fruit and increase yields.
In the five Central Highlands provinces of Kon Tum, Gia Lai, Dak Lak, Dak Nong and Lam Dong, soil conditions are suitable for the growth of coffee, pepper, rubber and fruit-trees. However, soils in these highland areas have a pH level below 4.5 and lack phosphate, potassium, calcium, manganese and micronutrients such as boron, zinc.
In the past, to achieve high crop yields, farmers mostly used chemical fertilizers, leading to serious soil degradation. Studies by the Western Highlands Agriculture and Forestry Science Institute and the Soils and Fertilizers Research Institute under the Ministry of Agriculture and Rural Development have proved that soils in the Central Highlands lack nutrient balance, which has an adverse impact on the health of plants, especially coffee.
In recent years, along with assessing soil quality, scientific research projects have been conducted to compare the effects of various kinds of fertilizer and identify suitable times to put down fertilizer for coffee, pepper, rubber plantations and orchards. Research results show that VADFCO’s fused magnesium phosphate and multi-element NPK fertilizers are especially good for plants grown in the Central Highlands.
Van Dien fertilizers have proved to be soil-friendly and good for plants. VADFCO’s more than 60 product lines have contributed significantly to bumper crops and become a reliable companion of Vietnamese farmers.
