Peanut kernels are rich in protein and fat. To form these substances, a lot of nutrients are needed. According to research, for every 100kg of peanut pods, pure nitrogen (N) 6.8kg, phosphorus (P2O5) 1.3kg, and potassium (K2O) 3.8kg are required. The most nitrogen is needed, followed by potassium and phosphorus. In addition, peanuts need more calcium.
Peanuts, like soybeans, have root nodules, which can fix nitrogen in the air. Only 1/3 of the total amount of nitrogen is absorbed from the soil during the whole growth period, which can meet the demand of peanuts. Other nutrients should be absorbed from the soil. . Due to the characteristics of peanuts on the ground and the characteristics of underground pods, peanuts not only absorb the fertilizer, but also the fruit cones and young fruits can absorb fertilizer.
The fat absorption characteristics of peanuts are generally more in the middle and less in both ends. Due to slow growth and low nutrient intake during seedling stage, the absorption of nitrogen, phosphorus and potassium only accounts for about 5% of the total growth period of the whole growth period. The flowering period is the period of rapid growth of peanut plants. In this period, a large number of flowering cones and nutrients are needed. The amount of nitrogen, phosphorus and potassium in the early maturing varieties reached the maximum, accounting for more than half of the total amount of absorption. The absorption of potassium in the late maturing varieties was nearly half in the flowering stage, and the uptake period of nitrogen and phosphorus reached the highest, accounting for the highest. More than half of the roots have weakened absorption capacity at maturity and reduced nutrient absorption.
