2For all types of peanuts, all recommend dolomitic
lime when Mg is low and lime is recommended.
3B=Banded over the row, BC = Broadcast; Gyp = Gypsum;
Ca = elemental Ca.
4If lime is recommended, growers are informed to apply
lime to the surface after turning to supply all Ca needs.
5Recommendation in lb Ca acre-1 instead
of gypsum to account for variability in moisture and Ca content
of gypsum products.
6North Carolina uses the Mehlich-3 soil extractant. |
