 Chebanse, IL..... | Asking for clarification....
Are you guys using the same removal rates we do in IL for your corn/beans put into strips?
The updated (2020?) values from U of IL are: Corn 0.37 lb P2O5 per bu removed grain only = 0.80 lb Dap or triple super per bu 0.24 lb K20 per bu removed grain only = 0.40 lb 0-0-60 per bu
200 bu corn would need 160 # Dap & 80 # of K in strip 250 bu corn would need 200 # Dap & 100 # of K in strip 300 bu corn would need 240 # Dap & 120 # of K in strip Dowdy 500 bu corn would need 400 # Dap & 200 # K
Beans 0.75 lb P205 per bu = 1.60 lb Dap per bu 1.17 lb K20 per bu = 1.95 lb 0-0-60 per bu
50 bu beans would need 80 # Dap & 98 # Potash 75 bu beans would need 120 # Dap & 146 # Potash Dowdy 190 bu beans would need 300 # Dap & 370 # Potash
Is this how you do your strip removal rate fertilizing? But, most don't strip till beans, right? So I assume broadcast fertilizer following beans? |
