Use products to turn water fern into organic fertilizer

The Department of Science and Technology of Thua Thien-Hue province, through the Center for Application of Science and Technology Advances, successfully implemented the project "Supporting the replication of the model of handling water hyacinth problem using Micromix-3 biological product as organic biological fertilizer".

The project was implemented in response to the current situation in Thua Thien - Hue, where water hyacinth has grown excessively in ponds, lakes, rivers and streams, obstructing the flow of water and affecting the daily life of local residents. In districts and towns such as Quang Dien, Phong Dien, Huong Tra, Huong Thuy, Phu Vang, Phu Loc..., water hyacinth has grown and reproduced rapidly, clogging ponds, lakes, canals and rivers; causing pollution and affecting the natural flora and fauna of the aquatic environment.

Localities in the province have to spend hundreds of millions of dong each year to collect duckweed and clear waterways before the flood season to limit bridge and culvert collapses caused by duckweed and garbage.

After being scooped up, the water hyacinth is put into the compost piles to ensure the required volume is achieved. The process of turning and adding Micromic-3 is followed according to the instructed technical process; the most favorable time to do this is around May-August (according to the solar calendar).

Within 1-3 months, the compost pile meets the requirements, the compost pile decomposes and decomposes well. From the results of the distributed and demonstration models in the project area, initially 250 households have accessed the technical process, as well as the benefits of using Micromic-3 to turn water hyacinth into organic fertilizer on the spot, used for family agricultural production.

Currently in the project area, most people use biological organic fertilizers mainly in growing vegetables, a few use them in growing flowers such as Thuy Van and Thuy Thanh communes (Huong Thuy town) and growing ornamental plants, fertilizing rice in Huong Vinh commune (Huong Tra town); Phu Da town and Vinh Thai commune (Phu Vang district).

According to people's feedback, after crops are fertilized with organic fertilizers, they have good growth rates, few pests and diseases, high quality products and high yield.

Regarding flower growing, the plants grow well, produce beautiful flowers (beautiful, bright flower color, good leaves, darker and more flowers), no pests are seen.

Notably, while the lowest price of bio-organic fertilizer on the market is 1,500 VND, bio-organic fertilizer using Micromic-3 product processed from water hyacinth costs only 860 VND/kg; this means that farmers save 860,000 VND per ton of fertilizer.

According to statistics from farmers' associations at all levels in the project area, 1,522 cubic meters of water hyacinth were collected from local ponds, lakes, and rivers; after being processed, nearly 254 tons of organic fertilizer were produced, meeting the requirements.

The Department of Science and Technology of Thua Thien-Hue province has requested local authorities to pay more attention and support people with the biological product Micromix-3 to contribute to promoting the replication of this model. Thanks to that, the efficiency will be doubled when farmers have more organic fertilizer to improve the soil and the water environment will also be significantly improved./.
