This is a experiment that i did last spring in soybean stubble. This field has been no-till since 1993.
What i did was the following. Looking at the legend the "csr" 1 was a 6ft x 6ft area that the residue was scraped off, no tillage was done.
The "tbs" in the legend was a 6ft x 6ft area that was tilled with a garden hoe about 2 inches deep.
The "sbr" was under soybean residue.
The "csr 2" was a 14 inch wide strip that was cleared of soybean residue
