Nghe An farmers turn water hyacinth into biofertilizer

(Baonghean.vn) - By applying technology, farmers in Quynh Luu (Nghe An) have used duckweed to compost into bio-fertilizer. The model helps farmers minimize the use of inorganic fertilizers such as nitrogen, phosphorus, potassium, etc., contributing to protecting the local environment.

Farmers mix water hyacinth with manure to make bio-fertilizer.

The family of Mr. Tran Ngoc Chung in Block 9, Cau Giat town is the third household in Quynh Luu district to receive technical assistance and capital support from the district's Agricultural and Fisheries Extension Center to build a model using duckweed to process and compost into biofertilizer.

During the process, Mr. Chung said: Water fern is easy to find, combined with some manure and microorganisms to make compost. This time, the family prepared 6 tons of water fern and 4 tons of manure. The water fern is cut into pieces, mixed in a ratio of 2 parts water fern and 1 part manure. Then, use microorganisms mixed with water and sprayed evenly on the surface. When the composting process is complete, use a tarp to cover the compost to create a high temperature for the above materials to decompose quickly. After 25 - 30 days, 4 - 4.5 tons of microorganisms will be produced, used to fertilize plants.

Before being put into compost, duckweed is chopped.

Faced with the reality that most farmers use chemical fertilizers over time, which will gradually make the soil infertile, using organic fertilizers will ensure better soil regeneration. Furthermore, it is found that water hyacinth in canals and ditches is quite large, causing blockage of water flow, affecting agricultural production. Therefore, encouraging farmers to scoop water hyacinth not only contributes to clearing canals but also creates a source of organic fertilizer, increasing humus and soil fertility.

Mr. Nguyen Anh Hung - Head of the Quynh Luu District Agricultural Extension Station said: "On that basis, we want to create a cleaner organic fertilizer for crops. By using a preparation, useful microorganisms BIO - F, this bacteria strain has the effect of quickly decomposing cellulose lines, organic substances to become high-grade fertilizer, used to fertilize crops, especially fertilizing high-grade crops such as flowers, vegetables, and high-value fruit trees".

Water hyacinth is abundant in canals in many localities. This is an abundant source of raw materials for making biofertilizer.

The composting model is an important direction for agriculture, because it not only increases the productivity of crops but also contributes to ensuring the environment. This method is being encouraged by the government to be replicated in localities.
