†For corn the 2000 rate would have been applied to soybean and vice versa.
††BP = Biennial P; BK = Biennial K; AP = Annual P; AK = Annual K. Parentheses indicate which crop the rate favors. Note: For DS chisel tillage multiply P rates by 1.5 and K rates by 2.0. Starting in 2004, both chisel and no-till plots at DS received 1.5× P rates and 2× K rates.
