Key innovations
This innovative technology uses environmentally friendly compound loss control agents, which are easy to combine with existing chemical fertilizer processes. It effectively reduces nutrient loss through a molecular trapping net mechanism, significantly improves fertilizer utilization, and significantly reduces environmental pollution.
Potential economic benefits
This technology can reduce the amount of chemical fertilizers by 10% without reducing production and increasing the production by 8%~35%, improving chemical fertilizer utilization rate 4~16 percentage points, significantly reducing agricultural investment and increasing farmers 'income.
Potential climate benefits
This technology directly reduces carbon emissions from chemical fertilizer production by reducing the amount of chemical fertilizer used. Loss control functions reduce nitrogen loss and indirectly reduce greenhouse gas emissions from farmland. At the same time, increase the content of soil organic matter, realize soil carbon sequestration, and contribute to carbon reduction benefits in many aspects.

Solution details

1. scope of application

Agriculture, chemical raw materials and chemical product manufacturing

2. Brief description of technology

Fertilizer nutrient loss control technology is to add a compound of environmentally friendly and low-cost inorganic materials (such as attapulgite and bentonite) and environmentally friendly organic materials to the fertilizer production process by adding blending and feeding devices. The addition process can be closely integrated with common fertilizer granulation processes (extrusion, rollers, towers, etc.), with minor changes to existing equipment and processes. After mixing and granulating, the loss control agent meets water to form a molecular trap net to "net" the nutrient elements of the chemical fertilizer, reduce nutrient loss and improve fertilizer utilization efficiency.

3. technical information

Under the same process conditions, the loss-control fertilizer particles are similar in size to ordinary fertilizer particles, with improved hardness and enhanced moisture absorption.

4. comprehensive benefits

A large number of field test data prove that by applying new control-loss fertilizers, production reduction can not be achieved without reducing fertilizer application by 10%; applying new control-loss fertilizers can improve chemical fertilizer utilization efficiency 4~16 percentage points, increasing grain output by 8%~35%; By applying new control-loss fertilizer combined with efficient straw return conversion technology, the soil organic matter content can be increased by 7% on average; applying new control-loss fertilizer can reduce ammonia volatilization by 28%~40%, reduce leaching by 19%~35%, calculated based on an average reduction of 25%. According to incomplete statistics, in 2016~In 2020, the sales volume of new control-loss fertilizers will be approximately 900,000 tons. The use of new control-loss fertilizers will reduce environmental nitrogen emissions by 27000 tons compared with ordinary fertilizers (calculation method: 900,000 tons × average nitrogen content of the product 20%× nitrogen fertilizer loss rate 60%× new product reduction rate 25%).
