Abstract: | A methodology was developed to estimate quantities of crop residues that can be removed while maintaining rain or wind erosion
at less than or equal to the tolerable soil-loss level. Six corn and wheat rotations in the 10 largest corn-producing states
were analyzed. Residue removal rates for each rotation were evaluated for conventional, mulch/reduced, and no-till field operations.
The analyses indicated that potential removable maximum quantities range from nearly 5.5 million dry metric t/yr for a continuous
corn rotation using conventional till in Kansas to more than 97 million dry metric t/yr for a corn-wheat rotation using no-till
in Illinois. |
