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

Fertilizer Characteristics: This fertilizer is rich in essential nutrients, with a total content of nitrogen, phosphorus, and potassium exceeding 45% (N15-P2O510-K2O20). It provides all the necessary nutrients for crops and soil fertility, and dissolves easily in water. It is suitable for a wide range of soils and crops, especially high-value economic crops. Crops that are sensitive to chlorine show particularly good results, with yield increases typically ranging from 20% to 30%. Fertilization Recommendations (kg per mu): - Tobacco: 30–35 kg as base fertilizer (compound fertilizer), 5 kg urea applied 30 days after planting. - Rice: 25–30 kg compound fertilizer as base, 15–20 kg urea during the early growth stage. - Corn: 25–30 kg compound fertilizer as base, 15–20 kg urea applied at the tasseling stage. - Cotton: 25–30 kg compound fertilizer as base, 15–20 kg urea at the jointing stage, split into two applications. - Potatoes: 28–32 kg compound fertilizer as base, 10–15 kg urea, applied twice. - Tea: 35–40 kg compound fertilizer as base, 20–25 kg urea, applied 2–3 times. - Vegetables: 80–100 kg compound fertilizer per acre as base fertilizer (40%), with the remaining 60% applied in 2–3 top-dressing sessions. - Fruit trees: Apply 0.7–1 kg per tree in autumn after harvest, during early flowering, and late growth stages. - Melons: 70–90 kg compound fertilizer per acre as base (50%), with the remaining 50% applied in two top-dressing sessions. Important Notes: Apply the fertilizer to the side of the seed or plant, not directly on it, to avoid burning. Adjust the dosage based on crop yield—higher yields require higher rates, while lower yields should use lower amounts. For crops like rapeseed and legumes, increase phosphate fertilizer application. In greenhouse vegetables, you may need to increase both the amount and frequency of fertilization. Adjust the timing of top-dressing according to local conditions and crop needs. This flexible approach ensures optimal nutrient uptake and maximum yield.
