How to Choose Fertilizer

Choosing Fertilizers: Select the right ratio for your crops, check labels to spot fakes, and maximize value. More expensive doesn't mean better—the best fertilizer is the one suited to your crops. Different crops and growth stages have vastly different nitrogen, phosphorus, and potassium needs. Choose the right ratio to double fertilizer efficiency while using less.
1. Core Formulations by Crop: - Grain crops (wheat, rice): Prioritize N-P-K 15-15-15 balanced fertilizer + supplemental nitrogen later; - Fruit/vegetable crops: High-potassium compound fertilizer (e.g., 10-8-22) during fruiting stage for fruit enlargement and sweetness; Leafy vegetables require high nitrogen for vigorous stem and leaf growth.
2. Verify legitimate labeling: Packaging must display the fertilizer registration number, compliance standards, and nutrient content—all are essential. Products without registration certificates are counterfeit goods; avoid them regardless of price. Reject fertilizers with vague nutrient claims, such as “N-P-K ≥45%” without specific values.
3. Tips for small-scale growers: Avoid bulk premium fertilizers. For limited cultivation areas, choose specialized fertilizers from reputable brands in standard packaging. Purchase only what you need to prevent nutrient degradation from prolonged storage.
