AI Technical Summary
Existing stable fertilizers rely on chemical inhibitors, which have problems such as being environmentally unfriendly, having unstable effects, and being costly. They are difficult to apply to all soils, and the combined use of urease inhibitors and nitrification inhibitors can lead to resistance, resulting in unstable fertilizer yield-increasing effects.
Filamentous Pristiella is used as a strain with urease inhibition and nitrification inhibition functions. Combined with encapsulating agents such as trehalose, polyglutamic acid, molasses, palm oil and epoxidized soybean oil, a bio-stable fertilizer is prepared by disc granulation or drum mixing to ensure the activity and colonization of the microbial agent in high temperature, high salt and soil environments.
It has achieved efficient suppression of ammonia volatilization and nitrate leaching loss of stable fertilizers in different soil environments, improved crop nitrogen utilization, reduced environmental pollution risks, and reduced production costs.
