Title: Innovations of Yun Geng in Controlled Release Fertilizers
Introduction
Yun Geng is a notable inventor based in Shandong, China, recognized for his contributions to the field of controlled release fertilizers. He holds three patents that focus on enhancing agricultural practices, particularly for peanut cultivation in saline-alkali soil.
Latest Patents
One of his latest patents is a special film-coated controlled release fertilizer for peanuts in saline-alkali soil. This invention integrates various ingredients aimed at improving salt resistance, preventing etiolated seedlings, controlling diseases and pests, promoting growth, and enhancing pod plumpness. It effectively controls the release period of nutrients, improving fertilization efficiency without the need for top application throughout the growth period, thus saving labor costs. Another significant patent is a special film-coated release calcium fertilizer for peanuts, which features a three-layer structure. The inner layer consists of calcium nitrate, humic acid, seaweed extract, and adhesive, while the intermediate layer includes calcium nitrate, urea formaldehyde powder, and chitosan oligosaccharide. The outer layer is made up of urea formaldehyde powder and fermented livestock and poultry manure. This controlled release calcium fertilizer begins releasing calcium approximately 50 days after application into the soil, starting from the pod-bearing stage.
