Edible Gardening 0 views
The Soil and Fertilizer Institute of Hunan Province has developed a degradable-film controlled-release fertilizer for rice that can be widely applied in rice-growing regions of China with no side effects. Using natural and semi-natural polymer materials as the main coating components and adopting a self-developed new fluidized dual-spray-bed coating process, the Soil and Fertilizer Institute of Hunan Province developed a degradable-film controlled-release fertilizer whose nutrient release can be artificially controlled within 30 to 330 days. This controlled-release fertilizer is non-toxic, completely degrades within 2 years after being applied to the soil with no residue, and can reduce fertilizer pollution of the atmosphere, soil, water bodies and other environments.
