I need poetry. Take advantage of the waste, by-products in agriculture Making organic fertilizer both helps clean up the environment, reduces emissions, creates jobs and increases incomes for farmers.
Each year, the DPRK produces about 24 million tons of rice and as much straw is dumped in its fields. This is Le Hoang Vu.
Every year the DBSCL region produces about 24 million tons of rice, as much straw is thrown into fields. The use of sewage and by-products in agriculture to make organic fertilizer both contributes to cleaning up the environment, reducing pollution and emissions, creating jobs, increasing incomes, and providing an abundant source of organic fertilizers for the soil.
Ms. Phạm Thị Minh Hiếu, Head of the Department of Crop Growth and BVTV TP Can Tho said: "In the current time high prices for materials have put pressure on agricultural producers". That is why Can Tho's agriculture has been associated with International Rice Research Institute (IRRI), Agricultural University (TP HCM) and University School Currency We've been instructing farmers to use their straw instead of throwing it away, taking the fertilizer and turning it into organic fertilizers for their crops, helping them reduce costs and increase profits.
According to Hiếu, over time the agriculture sector in Can Tho has implemented pilot models of rice cultivation using organic fertilizer from straw combined with technological advances 1 must 5 reduction in the districts of Thu Lai, Cờ Đỏ and Thốt Nốt. . Through the results of evaluations, the model helps farmers reduce between 35 - 40% of the cost of fertilizers, chemical drugs and increase profits by 10% on the same area compared to traditional production.
Using agricultural waste as organic fertilizer helps clean up the environment, reduce emissions, create jobs and increase incomes for farmers. This is Le Hoang Vu.
According to Dr. Nguyễn Văn Hùng, Head of Mechanization and Post-Harvest Group - International Rice Research Institute (IRRI), the technology for producing organic manure from straw helps ensure quality, cost is about 50% cheaper than fertilizer on the market. Organic decomposition has a soil regenerating effect, improving agricultural product quality ensuring safety for consumers. A distinct advantage of this technology is the combination of mechanical (physical) and biochemical processes to optimize the efficiency and organic quality of rubber decomposition process.
As a result of evaluating many rice crops, farmers using organic fertilizer reduced the cost of fertilizers and pesticides by 35-40%, while profits increased by 10% on the same area compared to traditional production. This is Le Hoang Vu.
Speaking about the straw manure technique, Mr. Hung further shared: In case of manure using straw and cow dung, the corresponding ratio between these two types of materials is 6/4, however it also depends on the humidity of the raw material.
For straw after mushroom cultivation (50-60%) and cow manure (60-70%), the mixing ratio is respectively 1. 2:1, with C/N = 26. 1. In case of using 14% dry straw and 30% dried cow manure, the respective ratio is 1:1.
Straw material with higher humidity than required should not be sprayed with water during the mixing process. In case of raw materials are dry straw and field soil in a ratio of 7: 3 about the same moisture 30%, 0. 5% URE, 1% P, 0. 3% K and 0. 2% honeydew sugar.
The finished organic fertilizer process, after cooling, about 45 days after the first stirring, is ready for use. This is Le Hoang Vu.

The quality of the finished organic fertilizer is assessed through indicators on components C, N, P, K, C/N ratio, pH, humidity. From experimental results for many different types of materials, the product's C/N ratios are 1314. 5, pH: 6. 87. 2, 3540%, then spread evenly indoors to reduce moisture to 30% before mixing as a body frost or sunbathing to 14% moisture before going through the compression pellet process.
In the future, it is recommended that people increase their use of organic fertilizer from post-harvest straw in order to reduce environmental pollution, while utilizing and regenerating abundant organic resources, ensuring a trend towards clean agriculture development and demand for organic food.
What do you think?
