Production of biological organic fertilizers
(Baonghean) Mr. Tran Van Tien's household (Hamlet 5, Hoa Son) produces 5,000 square meters of land, of which 1,500 square meters are double-rice fields, the rest is for growing corn and sugarcane. When harvest season comes, corn stalks and sugarcane leaves can only be brought home to light the fire, but they are not firewood, so they are often piled up for termites to come and eat. In 2010, after the Commune Farmers' Association launched a campaign to use agricultural by-products as fertilizer, he was still hesitant because his family's fields are mainly for growing sugarcane and corn, plants with stems and leaves as stiff as wood, who knows when they will decompose into fertilizer!

The first batch of fertilizer he only tested was 2 tons, the main ingredients were garbage, bagasse, corn combined with cow and pig manure. For each ton of fertilizer, in addition to 700 kg of agricultural waste, 300 kg of manure, he added 2 kg of compost maker, 3 - 5 kg of molasses (or sugarcane molasses), 2 kg of urea, 3 kg of potassium: 5 kg of phosphate, 5-7 kg of lime powder and about 70 - 80 liters of water. Through a number of steps of composting, tilling, and mixing according to the correct technical process, about 1 month later, all the waste by-products had decomposed, becoming a loose, dark black fertilizer.
Farmers' Association Chairman Tran Van Tien (Hamlet 5, Hoa Son, Anh Son District) prepares organic fertilizer for the spring crop.
That year's crop, from rice, corn, sugarcane on his family's fields all grew well, resistant to pests and diseases. When the harvest came, the yield was much higher, he was confident that he had chosen the right investment. After that season, he collected all the by-products that his family had to make over 4 tons of bio-organic fertilizer. Although it only met a part of the demand, he was always willing to sell it to people in the area to try. He said, compared to the bio-organic fertilizer produced by the Sugar Factory at a price of 2.5 million VND/ton, he only sold it to people for 1.8 million VND/ton and saw a profit. If households produced it themselves, they would save a lot of costs.
Although Mr. Nguyen Van Mao in Hamlet 5 Hoa Son does not have much land, he saw that the commune launched a movement to produce biological organic fertilizers and wanted to test it out. With more than 500 square meters of sugarcane land in his garden, he dedicated 4 rows to test fertilizing with biological organic fertilizers. The results showed that the rows of sugarcane fertilized with this type of fertilizer all grew quickly, had green leaves, thick stems, and higher yields. He became a propagandist to encourage people to produce and use organic fertilizers to clean the village and improve the fields.
Mr. Le Van Tri - Vice Chairman of the Farmers' Association of Anh Son district said: Currently, farmers are overusing chemical fertilizers in agricultural production, causing many areas of cultivated land to become infertile, hardened and gradually losing the ability to cultivate. To restore the fertility and richness of the soil, it is necessary to fertilize with organic fertilizers. These fertilizers, if bought from the market, are quite expensive, while in rural areas, there are many raw materials to produce good fertilizers for the fields.
With that concern, in 2009, the District Farmers' Association coordinated with the Center for Science and Technology Application of the Department of Science and Technology to transfer production techniques, and directed the piloting of more than 300 tons in 20 households of Hung Son commune. From the results of field comparison, biological organic fertilizer was quickly enthusiastically responded by many members and farmers of Hung Son.
In 2010, the District Farmers' Association launched a mass production campaign in the entire district with over 1,550 tons. In 2011, despite unfavorable weather, the entire district produced about 2,000 tons. Typical examples are the communes of Tao Son, Linh Son, Binh Son, Hoa Son, Dinh Son, Phuc Son, Tam Son... This type of fertilizer is not only popular in tea and sugarcane farms, rice fields, and corn fields, but has been invested in by farmers to fertilize watermelons, cucumbers, and other vegetables.
Coming to Anh Son in the first days of the new year, the spring production atmosphere is bustling and urgent. Truckloads of organic fertilizers are being favored and trusted to gradually replace inorganic and chemical fertilizers. Next to the piles of compost that are gradually decreasing, farmers are collecting waste and agricultural by-products to prepare fertilizer for the upcoming crops. After the Provincial People's Council approved the policy of supporting 60% of the cost of purchasing compost maker biological products, the Farmers' Association at all levels in the district is striving to produce over 4,000 tons of fertilizer in 2012.
