Excerpt from the 41st Experiment Station Annual Report:

Two series of fertilizer experiments with cotton, corn, and small grains were started this year. The largest of these is the potash investigation which was made possible by a grant from the Agricultural and Scientific Bureau of the N.V. Potash Export My. This series of experiments includes about 20 acres divided into tenth-acre plots and planned so as to give information as to the influence of time, rate, method of applying, residual effect, and sources of potash when applied to cotton and corn and several other crops. This soil is very well suited to experimental work of this kind, as indicated by some of the results this first year. On plots where no potash was used the yield of seed cotton was only 240 pounds compared with from 530 to 800 on different plots receiving potash. In another series where no fertilizer was used, only 140 pounds of seed cotton were secured per acre as compared to 893 pounds where application of 800 pounds of high grade fertilizer was used.

Today, Clemson Extension agents continue to provide a wide variety of research-based information to the people of South Carolina. Agents are located in all 46 counties and at the University's five Research and Education Centers.
