Leesburg, Ohio | Yes, Puff, I agree that everything must be looked at in context. Certainly, adding manure to the equation from purchased hay or other purchased feed should be considered. That would fall in to the category of replacing nutrients removed by the crop, would it not?
My definition of long term really does not matter. Set it to be whatever you want. The fact will still remain that over whatever you period you want to use, a cropping program is going to remove a certain amount of nutrients. Putting back less than that amount (whether it be from commercial fertilizer, manure, or whatever source) will reduce the soil test levels of those nutrients, even if it is only one year. Part of my point was accepting the unstated fact that a good crop might still be grown for a couple seasons regardless of the fertility program. But one year or ten, that kind of program will sooner or later catch up to the reality that there will no longer be adequate nutrients available for optimum production. | |
