What is the % of nutrient loss associated with fall floating fertilizer?
Has anyone done or know of a company that has done multiple soil samples to calculate the nutrient loss from fall float to seeding? I know that there's lots of variables to consider but surely someone has some data.
We have fall floated fertilizer for the last several years. The cost to have it custom applied is easily justified by the spring logistics and limits of our equipment. We are considering purchasing a pull type boom floater or spin spreader to recapture the cost of custom work. We know that there is some product loss over winter. Not much, but enough. We have tried to get soil testing done to put a number to it but haven't been able to get samples when needed for various reasons.
I want to know if there is a place to find a % loss for each product applied as it sits in the field over winter. Currently we don't use Nitrain or agritain to reduce gas-off and will be considering that aswell. Thanks in advance
We use to put nh3 down in the fall. And assume 15-20% loss. The price difference between spring and fall is so little now. I don't think it ...More

I am also interested in this information on N, P, and K.
It is all over the place. I am assuming you are referring to urea. Generally if you have moist soil but drying, warm-hot temperatures, and s...More
