Importance of Gypsum for Virginia Market Types Peanut Notes No. 21 2019
There is no substitute for gypsum for Virginia market types. There are various liquid products available in the market place but they complement or supplement gypsum in some instances. However, gypsum is a fundamental element of production of all Virginia market types. Data are very limited on compatibility of pesticides (fungicides, insecticides, herbicides) with liquid calcium products. It would be wise to try these types of calcium products on a small portion of your acreage before deciding to shift away from gypsum. Your local county agent or the peanut team at NC State University can help with designing a simple trial to compare these and other products.
