The purpose of this investigation was to determine the practicability of placing an organic wedge in a solodized-solonetz soil and to compare the effect of it to other mechanical and cultural practices currently used for improving grain yield, root growth, and moisture in filtration, such as subsoiling chisel or deep rooted legumes in a crop rotation.
