| I am familiar with the N calculator that gives the most economical return based on corn sales price and N source cost
Is there a similar calculator for P and K?
I have some rented ground that was mined by the previous renter before I rented these fields. They are low in both P and K. Historically I would put on removal rates for the expected yield for P and K plus a few extra lbs depending on my cash position and expected crop price
This year economics are tight. Just wondering is there a ROI curve for P and K on needs and yield?
If so, how does one calculate being at the maxi bang for the buck especially on cash rent ground where year to year is always a variable? | |
