Fig. 4.âDiagram showing the average moisture content of the soil on plat B5-8, which was cropped annually to oats, and on plats A4-5 and A4-6, which were cropped biennially to oats, at the San Antonio Experiment Farm, January, 1910, to October, 1913. On each sampling date all the plats were sampled to a uniform depth, in most cases 6 feet, but in some instances 3 feet. 1910 and 1912 the moisture content of the fallowed plat was somewhat higher than that of the continuously cropped plat, and in 1911 it was nearly the same. At harvest time in 1911 and also in 1912 the moisture content of the fallowed plat was somewhat lower than that of the continuously cropped plat, and in 1913 the moisture content of both plats was about the same. It appears from this that fallowing resulted in a higher moisture content in the fall at planting time for oats, and that when the land rema
