Effects of different tillage treatments on crop yields and soil physical properties
Authors: Kemp, J. G. And S. J. Bourget
Description: The moldboard plow is the leading tillage implement in eastern Canada for the initial preparation of seedbed from sod or torn stubble. Attempts have been made to modify, replace, or supplement moldboard plowing to in crease yields in many areas of similar climatic conditions. The moldboard plow has not yet been replaced as a primary tillage implement. The results of several workers (10, 12, 13) indicate that operations such as deep plowing were beneficial under very limited conditions. Comparisons were made between the moldboard plow and chiselling (12, 15), discing (4), and sub-surface tillage (3, 9, 14), and the results were favorable to plowing. Increased weed population in non-plowed plots (15) was found to contribute to reduced yields. The interest in subsoiling has been re generated by the introduction of sub soil fertilizing and liming (1, 2, 5, 7, 11). Bertrand and Kohnke (1) reported that, when subsoil fertilizing and liming to a depth of twelve to eighteen inches were carried out, yield increases of 29, 9, 7 and 0 percentages were obtained for corn, soybeans, hay and wheat, respectively. As indicated also by the other reports, increases in crop yields due to subsoil fertilizing and liming usually occurred on packed acid subsoils low in fertility.
