Fertilizer demand and application amount of fertilizer in rice
Corn: For every 100 kg of corn grain produced, approximately 2 to 4 kg of nitrogen, 0.7 to 1.5 kg of phosphorus, and 1.5 to 4.0 kg of potassium are needed. If the goal is to achieve a yield of 400 kg per mu, it's recommended to apply around 40-60 kg of ammonium sulfate or an equivalent amount of other nitrogen fertilizers. Additionally, 40-60 kg of superphosphate (containing 10% to 16% available nutrients) should be used, or alternatives like heavy calcium phosphate (36% to 52% active ingredients) or calcium magnesium phosphate (12% to 16% active ingredients). For potassium, about 6 to 10 kg of potassium sulfate (48% to 52% active ingredients) or potassium chloride (50% to 52% active ingredients) is advised. As an alternative, plant ash can be applied at 40-60 kg per mu, using dry ash without impurities.
When deciding on the amount of fertilizer for corn, several factors must be considered, such as the type of corn, variety characteristics, expected yield, soil quality, and local climate. In the early seedling stage, corn plants are small and grow slowly, so their nutrient uptake is minimal. However, during the jointing and booting stages, growth accelerates, and both vegetative and reproductive development occur simultaneously, leading to a significant increase in nutrient absorption. After this phase, nutrient uptake declines sharply, and the plant’s growth becomes nearly stagnant.
Rice is one of the crops with high fertilizer requirements. On average, for every 500 kg of rice and straw produced, the crop absorbs 6.7 to 15.8 kg of nitrogen, 3.9 to 8.1 kg of phosphorus, and 9.6 to 26.7 kg of potassium. The typical N:P:K ratio is 1:0.5:1.5. However, actual fertilizer needs can vary depending on the region, variety, and cultivation practices. To meet a yield target of 400-600 kg per mu, it's generally advisable to apply around 40-60 kg of ammonium sulfate (10%-21% active nitrogen), or an equivalent amount of ammonium bicarbonate (16.8%-17.5% active nitrogen), ammonium chloride (22%-25% active nitrogen), or urea (45%-46% active nitrogen).
The peak nutrient uptake by rice occurs before heading, especially for nitrogen, phosphorus, and potassium. Nitrogen absorption peaks 20 days before heading, while phosphorus uptake remains relatively consistent throughout the growing season, with the highest rate occurring between tillering and young panicle differentiation. Potassium uptake is most significant from panicle differentiation to heading, followed by the tillering to panicle differentiation stage. Ensuring adequate potassium supply during these critical periods is essential for optimal yield and quality.
