Peanut nitrogen deficiency, leaves from the old leaves began to fade to yellow, leaves become smaller and thinner, plant growth will be shorter than the yield-increasing plants. After summer stubble peanuts enter into autumn, peanuts enter the critical period of fruit expansion, if Rain Water is too much, it will cause the loss of trace elements in the soil, such as iron, zinc and nitrogen, especially in sandy land.

Solution: after the occurrence of yellow leaves in peanuts, the sprayer uses 0.1% urea of about 10 grams, after spraying once, the phenomenon of yellow leaves of peanuts can be effectively controlled.
