Precision Application of Gypsum Peanut Notes No. 107 2019

Question:

Have you seen any difficulties with prescription applications of landplaster?

Jordan answer:

Depends on what you are basing the rates on. Using soil test information to decide if gypsum is needed and what rate is needed has been unpredictable for Virginia market peanut varieties. The relationship between soil calcium and yield response is poor. That is our reason for making a general recommendation across all Virginia market types and fields at a common rate.
