The experiments reported in this paper were planned to compare muriate of potash, sulfate of potash, and kainit as sources of potash for cotton in fertilizers mixed with superphosphate and nitrogen materials. These experiments are a part of general fertilizer invest~gatiofis pertaining to cotton problems in the southeastern states. The suitability of-potash materials containing chlorine, especially when used in large amounts and on sandy soils of the southeastern Coastal Plains, is of considerable interest and many inquiries coneernlng their effect on yield and quality of the agricultural products. grown there have been recMved. The effect of chlorides, applied td the soil, on crop yields has been the subject of experimentation for many years and investigations have been made with pots and water cultures. The results generally agree that if chlorine is necessary for normM plant growth, the quantity required must be small. It is generally shown that plants differ in their response to this element and vary in tolerance to increasing quantities. The literature on the effect of chlorine on plant growth has been reviewed by Tottingham (5) 3 and Loman~tz (~) and more recently by Garner, et al. (2), and its further development is riot deemed essential in connection with this paper.
