China's Compound Fertilizer Development Faces Challenges with Soil Nutrient Accumulation
Compound fertilizers in China are mainly common type (15-15-15) with 54% market share, while special types have 46%. High-analysis fertilizers have over 40% nutrients. This leads to excess nutrients in soil and high fertilizer prices. To meet crop needs accurately, special compound fertilizers tailored to specific growth stages based on soil tests are needed.
