Soil Test Guidelines:
• Enter available nutrient content in kg/ha (based on soil test results)
• For ppm values: multiply by 2.24 to convert to kg/ha
• Recommended soil testing: N (KMnO₄ method), P (Olsen method), K (NH₄OAc method)
• Test soil 0-20cm depth for accurate results
Fertilizer Selection Guide:
• Compound fertilizers provide balanced nutrition in single application
• Urea: High nitrogen content, ideal for vegetative growth
• DAP: High phosphorus, excellent for root development
• Muriate of Potash: Pure potassium source for fruit/grain filling
• Consider soil pH, crop stage, and weather conditions

Questions fréquemment posées

What do NPK ratios mean and how do I choose the right one?
NPK ratios represent the percentage of Nitrogen (N), Phosphorus (P), and Potassium (K) in fertilizer. Choose based on your crop needs: high N for leafy growth, high P for root development and flowering, high K for fruit development and disease resistance.
How do I determine the correct fertilizer application rate?
Application rates depend on crop type, growth stage, soil test results, and yield goals. Start with soil testing to determine existing nutrient levels, then calculate based on crop nutrient removal and target yield.
Why is soil testing important for fertilizer calculations?
Soil testing reveals existing nutrient levels, pH, and organic matter content. This prevents over-fertilization, reduces costs, minimizes environmental impact, and ensures nutrients are available to plants.
When is the best time to apply fertilizer?
Timing depends on crop type and nutrient mobility. Apply nitrogen when plants actively grow, phosphorus at planting or early growth, and potassium before planting or during early development. Split applications often improve efficiency.
