What are the key points of fertilization techniques for spring peanuts?
Calcium can promote pod formation, reduce empty pods and increase the number of filled pods; applying calcareous fertilizer such as lime to acidic soil can also reduce soil acidity and benefit nitrogen fixation by root nodules. Therefore, calcareous fertilizer can improve peanut yield and quality. When peanuts are deficient in calcium, plant growth is slow, roots are thin and seedlings are weak, and the edges and surface of old leaves will show...
