Latest Rice Fertilizer Requirement Patterns and Fertilization Techniques Tutorial
Rice Fertilizer Requirement Patterns Rice is one of the crops with relatively high fertilizer requirements. Generally, producing 100 kg of rice grain requires 1.6-2.5 kg of nitrogen (N), 0.8-1.2 kg of phosphorus (P2O5), and 2.1-3.0 kg of potassium (K2O). The fertilizer requirement ratio of nitrogen, phosphorus, and potassium is approximately 2:1:3. Rice's absorption of nitrogen
