Development and Application of Bio-organic Fertilizer Based on Diammonium Phosphorite

Thread Content

Development and Application of Diammonium Phosphorus Fertilizer as a Biochemical Organic Fertilizer. This product is a special biochemical organic phosphorus fertilizer with complete nutrient profiles and multiple functions, resulting from comprehensive reactions in inorganic chemistry, organic chemistry, electrochemistry, biochemistry, and microbiology, followed by biological engineering transformations. Project Name, Index Requirements: Total nutrient content (calculated as N+P2O5+K2O) % ≥25; Organic matter content % ≥20; Humic acid content % ≥5; Moisture content % ≤7. The innovation of this product lies in its microbial engineering transformation, which falls under \"active genetic engineering\" and gene induction engineering. Advantages: 1. With each application, the fertilizer’s effectiveness lasts for 1–3 growing seasons, requiring virtually no additional fertilization ； 2. No inherent or acquired pollution or toxicity is generated in farmland soil and farmland areas ； 3. Possesses stress resistance capabilities (including resistance to natural disasters and pests and diseases) ； 4. Intelligent feature: it can achieve a nutrient balance that meets the physiological needs of crops at different growth stages for various crops. Its technical maturity is 100%, compared to 80–90% for tutoring; after the fourth round of improvements, it can reach international advanced levels. Although this fertilizer has only just entered the commercial phase, its social and economic benefits are already becoming apparent. By the end of 2000, over 5,400 tons of the fertilizer had been sold, in 37 different varieties; it was used on 300,000 mu of land, resulting in an overall increase in yield of about 24.5 million kilograms, with total revenue reaching around 29.4 million yuan. The production scale still needs to be expanded, and there is insufficient promotion of green crops. Our promotion plan for this year is to reach an area of 3–5 million mu under promotion within one year.
