Description
The use of subsurface tillage machines has steadily increased during the past few years. They consist primarily of a blade running several inches beneath the soil surface so that the soil is tilled or stirred without being turned over. Straw and other crop residues are thus left almost undisturbed on the surface of the soil to provide protection against erosion and run-off. The best results from this type of tillage have been obtained in areas whore combines are used to return all straw to the land. Under these conditions increased crop yields have resulted from the use of subsurface tillage. Weeds may not be so effectively controlled by subsurface tillage in the eastern part of the state but crop yields obtained from field trials have been about equal to those from other types of tillage. In addition to field trials conducted in several parts of the state detailed tillage and residue trials were conducted at two locations, one at Highmore and one northeast of Huron.
