Calcium Levels in Soil Peanut Notes No. 147 2021

Question:

What do calcium levels look like on peanuts? Already had 1500 pounds but a lot of rain.  Samples taken at 2 inch depth.  What’s my parameters?

Jordan Answer:

For Virginia market types there is no clear relationship between soil calcium and yield.  It’s just too variable in terms of predicting a response and that is why we recommend gypsum on all Virginia types and at least half of the Virginia rate in jumbo runners.  When did the 1500 pounds go out?  I recommend re-applying half of the rate if applied when peanuts are small (early June) and there is a big rainfall event shortly after application.  5 inches in a few days.  Outside of this, I think you have done all you can to get calcium in place.
