After applying gypsum to the saline-alkali peanuts, the pH of the soil can also be adjusted to reduce the damage of the excess sodium salt in the soil to the root system. According to local comparison tests, peanuts with calcium fertilizer generally increase yield by 5% to 20%, and those with higher rates can reach more than 30%.
Peanut application of calcium fertilizer can produce high yield
Peanut is a calcium-loving crop (according to the measurement, it needs to absorb 2.7 kg of calcium per 100 kg of peanut pods). When the seeds are germinated, calcium nutrition is needed. Calcium can strengthen the metabolism of nitrogen in the plants and promote roots and nodules. development. When the peanut is deficient in calcium, the root system is weak, the young stems and leaves are yellow, the back of the leaves is spotted, the germ of the seed becomes black, the pod development is reduced, and the empty fruit and single fruit are increased.
