Farmers increase the use of organic fertilizers, reducing input costs for the spring crop.

Proactive source of organic fertilizer

Ms. Nguyen Thi Danh in Hamlet 4, Hau Thanh Commune (Yen Thanh) said that her family has more than 4 sao of land to produce 2 rice crops, and in previous years, they usually used just enough inorganic fertilizer to fertilize the rice. However, this year, due to the high increase in inorganic fertilizers, especially some fertilizers increased 3 times compared to last year, so the family had to find ways to reduce input costs, focusing onincrease the amount of organic fertilizer, reducing the amount of inorganic fertilizer. Therefore, for the past few months, Ms. Danh's family has been using the waste of 2 buffaloes and a flock of nearly 100 chickens to make organic fertilizer.

“Every day, we put rice husks and straw in the buffalo pen and chicken coop. After a short time, we clean up the barn and dump all the waste into a pit to compost. It is expected that this winter-spring crop, the family will produce over 1 ton of organic fertilizer for rice, significantly reducing the amount of inorganic fertilizer compared to before. For inorganic fertilizers, because nitrogen fertilizer has increased too much, the family has reduced the amount of nitrogen fertilizer and increased the amount of compound fertilizer (NPK) to reduce the cost of buying fertilizer,” Ms. Nguyen Thi Danh shared.

Some farmers in Quynh Luu and Dien Chau districts... believe that in order for rice plants to grow stably and strongly, in addition to inorganic fertilizers, it is also necessary to...manure, so this season, focus on increasing the amount of organic fertilizer to reduce costs. Currently, many families have proactively gone to cattle farms to buy manure to compost with straw. Farmers also hope that agricultural cooperatives need to promptly contact key agents to supply inorganic fertilizer to farmers at the lowest price.

Mr. Le The Hieu - Head of the Department of Agriculture and Rural Development of Dien Chau district said: This spring crop, the whole district planted more than 9,000 hectares of rice. Faced with the pressure of sharp price increases of inorganic fertilizers, the district directed localities to regularly propagate and guide farmers to increase the use of organic and microbial fertilizers; at the same time, reduce nitrogen fertilizers, increase the amount of synthetic fertilizers so that rice plants grow stronger and reduce pests and diseases. Previously, many families applied too much nitrogen fertilizer, leading to rice growing leaves, creating conditions for pests and diseases to develop and rice yield was also reduced.

Currently, many families do not maintain raising buffaloes, cows, etc., so to have enough manure to fertilize their fields, households need to proactively go to cattle farms to buy manure. This is also a solution to reduce input costs when inorganic fertilizer prices increase.

Combine lime powder to improve soil

Mr. Nguyen Tien Duc - Head of the Department of Crop Production and Plant Protection recommends: In the situation of inorganic fertilizers increasing sharply in price, affecting farmers' investment costs in production, therefore, in the upcoming spring rice crop, farmers need to increase the amount of organic fertilizers to fertilize rice.

Accordingly, manure from buffalo, cow, pig, chicken, etc. should be composted for a certain period of time for fertilization; combined with increased application of lime powder to improve the soil, creating ventilation for better root development. Inorganic fertilizers are indispensable for rice plants, but farmers need to balance the amount of fertilizer appropriately, possibly reducing nitrogen fertilizer and increasing compound fertilizer.

In addition, people need to applySRI improved rice cultivation techniques, to increase productivity and reduce costs in rice cultivation. Applying the improved rice cultivation technique SRI will help farmers save about 30% of seeds, save irrigation water (from 40-50%), reduce the amount of pesticides, increase productivity by 10-15% compared to conventional production and significantly improve the mechanical composition of the soil. SRI is welcomed by farmers because of its simple and easy-to-implement techniques such as transplanting young seedlings, sparse planting, single-crop planting, regulating water according to growth stages, weeding and stirring mud and increasing the use of organic fertilizers.
