Eastern VA. No such thing as too many Magnums. | We use quite a bit of gyp for all the reasons mentioned so far. We are on a tidal river system to pull irrigation water from. We run into a salinity issue about 3 of every 10 years. Gypsum will offset some salinity issues. It is also a very good readily available source of calcium for cucurbits and pepper and tomato. Calcium deficiency will present itself as blossom end rot in the mentioned vegetables. There is also quite a bit used on peanut land throughout the southeast. When we pull soil tests, we check the sulfur content to know how much gyp to apply. We usually end up using somewhere between 1 and 2 tons per acre on the vegetable land. It definitely has a positive effect on percolation and soil structure. We do many wet harvests and have a lot of traffic on the vegetable fields. It helps a great deal. It does not affect ph. |
Drywall gyp on cropland?
