The Texas Agricultural Experiment Station for several years has conducted experiments on the broad aspects of green manuring. In 1940, 1941, and 1942 studies were made to determine the effect of plowing under hairy vetch in these experiments on the reaction of Lufkin fine sandy loam at College Station, Texas. It was found that plowing under hairy vetch produced a significant increase in the acidity of the soil, at least during the growing season of cotton which followed the vetch. The increase in acidity was more pronounced on the fallowed portion of the plots than on the plots planted to cotton. There were some differences in the pH values of soil samples taken at different dates, but the highest pH values were obtained from the sample taken in July.
