Description:
Tillage experiments were conducted on Burford loam and Lockport clay loam. Different implements and combinations of implements were used to accomplish nine methods of tillage. The mouldboard plough was used as a standard treatment and compared with other treatments using a plough equipped with sub-bases, a disk plough, a one-way disk, a field cultivator, and rotary tillage. Crop yields, power requirements, and the effect on soil physical properties were studied.On Burford loam, with a 5-year rotation of corn, oats, and hay for three years, the yield of oats was significantly better when the fall tillage included mouldboard ploughing. No tillage treatment resulted in significant differences in the yields of corn as silage, and of hay. On Lockport clay loam the crop yields from a rotation of corn, oats, hay, hay, fall wheat, and red clover, were not significantly affected by tillage treatment.Tillage treatments did not produce significant differences in soil aggregation, bulk density or aeration porosity in any year of the experiment. Significant differences were from year to year when the mean values of all treatments were compared.The power required to accomplish the tillage treatments was measured.
