It’s Time for the Pegging Zone or Calcium Soil Test in Peanuts

As peanuts have emerged and are growing in the early season before bloom, testing the soil for the calcium level in the pegging zone (top 3 inches) is important.

This test is to check the calcium levels at a 3-inch depth, where the peanut pegs and pods will be developing.  On our runner varieties, if there is at least 500 lbs/A of soil test calcium AND if the calcium to potassium (Ca:K) ratio is 3:1 or better, no additional calcium is needed.  If EITHER of these requirements is not met, then UGA recommends to apply 1000 lbs/A of gypsum or land plaster at early bloom.  Also remember, any peanuts grown for seed should automatically receive this gypsum application regardless of soil test calcium levels.
