Enhancing Sugarcane Growth and Improving Soil Quality by Using a Network-Structured Fertilizer Synergist

High usage and low efficiency of fertilizers not only restrict sugarcane production but also destroy the soil environment in China. To solve this problem, a network-structured nanocomposite as fertilizer synergist (FS) was prepared based on attapulgite (ATP) polyglutamic acid (PGA). Field demonstrations were conducted from 2020 to 2021. Leaching tests characterization used evaluate ability network structure control nutrient loss. The effects FS growth field quality investigated. results showed could effectively reduce nitrogen loss by 20.30% decrease at least 20%. Compared with same nutrition, enhance yield brix 20.79% 0.58 percentage points, respectively. Additionally, improved physicochemical properties, including reducing bulk density increasing contents nitrogen, phosphorus, potassium, organic matter. altered diversity bacteria bacterial richness. Our study shows has good loss, advance agronomic traits, improve quality. This work offers an option for sustainable development through novel FS.
