This rice fertilizer calculator will help you calculate the amount of fertilizer raw materials needed for rice planting.
Enter the land area where you are planting rice. The amount of fertilizer applied to rice mainly depends on its planting area.
As organic fertilizer contains multiple nutrients, it can improve the soil aeration, fertilizer absorption and water retention characteristics, promote the stable growth of rice plants, and obtain high yield and quality. Organic fertilizer is mainly used as base fertilizer.
Phosphorus and potassium fertilizer can enhance plant vitality, promote nutrient synthesis and transportation, strengthen photosynthesis, prolong the functional period of leaves, enrich grains and increase yield. The best base fertilizer is phosphate, and the best topdressing is potassium. For fields with sufficient organic fertilizer, 20-40 kg of phosphate fertilizer can be applied per mu, and 3.5-5 kg of potassium chloride can be applied per mu before tillering. Spraying phosphorus and potassium fertilizer at later stage of rice can promote grain filling and fruit bearing
