"Zhonghua" Brand Compound Fertilizer (45%) Fertilization Recommendation (K2SO4 Type)

Fertilizer Characteristics: This high-quality compound fertilizer is rich in essential nutrients, with a total N-P₂O₅-K₂O content of at least 45% (N15-P2O510-K2O20). It provides a balanced supply of nitrogen, phosphorus, and potassium, which are crucial for crop growth and soil fertility. The product is highly water-soluble, making it easy for plants to absorb and utilize. It is suitable for all types of soils and crops, especially cash crops. It has shown excellent results on chlorine-sensitive crops, typically increasing yields by 20% to 30%. Fertilization Recommendations (in kg per mu): - **Tobacco**: Apply 30–35 kg of compound fertilizer as base fertilizer, and 5 kg of urea as top-dressing 30 days after planting. - **Rice**: Use 25–30 kg of compound fertilizer as base fertilizer, and 15–20 kg of urea as top-dressing. - **Corn**: Apply 25–30 kg of compound fertilizer as base fertilizer, and 15–20 kg of urea as top-dressing. - **Cotton**: Apply 25–30 kg of compound fertilizer as base fertilizer, and 15–20 kg of urea during the jointing stage. - **Potatoes**: Use 28–32 kg of compound fertilizer as base fertilizer, and 10–15 kg of urea in two applications. - **Tea**: Apply 35–40 kg of compound fertilizer as base fertilizer, and 20–25 kg of urea in 2–3 top-dressings. - **Vegetables**: Use 80–100 kg of compound fertilizer per mu as base fertilizer (40%), and apply the remaining 60% in 2–3 top-dressings. - **Fruit Trees**: Apply 0.7–1 kg per tree in autumn after harvest, during early flowering, and late growth stages. - **Melons**: Use 70–90 kg of compound fertilizer per mu as base fertilizer (50%), and apply the remaining 50% in two top-dressings. Important Notes: Apply the fertilizer beside the seed or plant, not directly in the same spot, to avoid burning the seeds. Adjust the dosage according to yield expectations—higher yields require higher limits, while lower yields should use the lower end. For rape and leguminous crops, increase phosphate fertilizer application. In greenhouse vegetables, consider increasing both the amount and frequency of fertilization. The timing of top-dressing can be adjusted based on local conditions and crop development. Always follow best practices to ensure optimal nutrient uptake and long-term soil health.
