Issue 13/2015 - Ningxia has successfully developed a new environmentally friendly slow-release fertilizer

The project "Application Research of New Environmental Protection Slow-release Fertilizer in Agricultural Emission Reduction" hosted by the Academy of Agriculture and Forestry Sciences of Ningxia Hui Autonomous Region has recently successfully passed the review and acceptance
of the expert group organized by the science and technology department of the autonomous region.

It is understood that the project focuses on the research and development of slow-release fertilizer technology around local rice, spring wheat, winter wheat and corn crops, determines the optimal proportion of nutrients such as nitrogen, phosphorus and potassium and slow-release agents in slow-release fertilizer, and develops slow-release fertilizer varieties
suitable for local agricultural production.
Through the nutrient absorption characteristics, slow-release fertilizer nutrient release characteristics, and slow-release agent formula and proportion of different crop varieties, the yield increase effect and application methods
of four new environmentally friendly slow-release fertilizers suitable for use in yellowing irrigation areas were determined.

At the same time, scientific and technological personnel cooperated with enterprises to produce a total of 54 tons of slow-release fertilizer products, and 500 mu of promotion and demonstration were carried out in the yellowing irrigation area, and the average yield of rice slow-release fertilizer demonstration increased by 10.
85%, saving costs and increasing efficiency by 1533.
1 yuan/hm2; The average yield of maize slow-release fertilizer demonstration increased by 18.
08%, and the cost saving and efficiency increase were 1865.
7 yuan/hm2.
The average yield of winter wheat slow-release fertilizer demonstration increased by 1.
2%.

While reducing the amount of fertilizer applied, it has achieved the purpose of
reducing agricultural emissions and increasing efficiency.
