Potash Gypsum Question

— Written By

Question or Comment:

On a farm where we’re planting about 25 acres of peanuts I’m not sure where to go with my fertility due to the fact that I’m trying to make management decisions off of cotton soil test results. The lowest K-I I have on the farm in one field ranges from 15-29. Would It be worth my time to broadcast 60-100 lbs K20? I realize peanuts like previous crops K as well as the fact excess amounts can cause pod rot and interfere with pegging. Not sure where to go from here.

Thanks for your help in advance.

Answer or Ramble:

You will be okay broadcasting that amount. The key will be to have a good gypsum program. Many growers apply some potash on a regular basis but they always have a good gypsum program. Hope this helps.

Question or Comment:

When you say “The key will be to have a good gypsum program”, does that mean up your rate to compensate for the late application of potash? We finished planting this past Sunday (The 10’th) so I imagine they are at least cracking if not already establishing a stand.

Answer or Ramble:

Just apply the recommended rate on time and you should be okay.
