Calcium is essential for high quality peanuts, and that makes calcium management one of the more critical aspects of peanut production. Soil moisture plays a critical role in absorption of calcium.
Calcium is “passively” absorbed by the developing peanut fruit. In other words, the amount absorbed depends on the concentration of water soluble calcium in the soil solution and the amount of water absorbed by the plant.
Very little calcium is absorbed by the peanut foliage and essentially none is translocated from the foliage to other parts of the plant, including the developing fruit.
Failure to supply adequate soluble calcium in the pegging zone during pegging and pod fill will result in “pops,” poor pod fill, low seed germination and higher incidence of aflatoxin.
For more information on the uptake of calcium on the developing peanut, please see this article: WEATHER, PEANUTS and CALCIUM
