"Zhonghua" Brand Compound Fertilizer (45%) Fertilization Recommendation (K2SO4 Type)
First, fertilizer characteristics:
This compound fertilizer contains a minimum of 45% essential nutrients, with a balanced ratio of N15-P2O515-K2O15. It supports optimal nutrient uptake and soil fertility, is highly water-soluble, and delivers quick results. Importantly, it is chlorine-free, making it safe for sensitive crops. The application of this fertilizer can typically increase crop yields by 20% to 30%, depending on the crop type and growing conditions.
Second, fertilization recommendations (in kg per mu):
For base fertilizer (compound fertilizer) and top-dressing (urea), the amounts vary by crop. For example:
- Tobacco: 30–35 kg base fertilizer, with about 5 kg urea applied later.
- Cotton: 30–35 kg base fertilizer, around 10 kg urea applied 30 days after planting.
- Flowering potatoes: 28–32 kg base fertilizer, about 10 kg urea during flowering.
- Watermelon: 40–50 kg base fertilizer, around 10 kg urea before flowering.
- Tea: 60–70 kg base fertilizer, approximately 20 kg urea applied in two or three stages.
- Rice: 25–30 kg base fertilizer, around 13 kg urea during the young panicle differentiation stage.
- Rapeseed: 30–35 kg base fertilizer, about 13 kg urea during the early growth phase.
- Vegetables: A total of 70–90 kg compound fertilizer annually, with 40% used as base fertilizer and the remaining 60% applied in 2–3 split applications.
- Fruit trees: After the autumn harvest, apply 1–2 kg of compound fertilizer per tree during early flowering and late growth stages.
Third, important application notes:
When applying fertilizer, ensure it is placed 5–8 cm below the seed or plant to maximize root absorption. For high-yield fields, use the upper limit of the recommended amount, while low-yield areas should stick closer to the lower end. If using this fertilizer on legumes, consider increasing the phosphate content for better performance. Adjust the timing and rate based on local weather, soil conditions, and crop development stages for optimal results. Always follow best practices to avoid over-fertilization and maintain soil health.
