Northeast Nebraska | Some people in our area have been adding in potassium thiosulfate 0-0-25-17S into their fertigation mix. It is a very expensive form of K at around $4.50 per gallon and 12.2#/gallon density. So $4.50 per 3# K and 2# S. How would it work to make a stock solution of dissolved potash? I have read that 290# potash can be dissolved in 100 gallons of water at 0 degrees C. This would allow 2900# of potash in a 1000 gallon nurse tank with water. This would get the cost per # of K down to around $0.30. Will potash really go into solution this well? Obviously they wouldn't be able to mix it with 32% or it would salt out. Has anyone used dry fertilizer to make liquid like this before? The article said that this method would work for urea and map as well. | |
