Abstract

One of the most important questions connected with the alkali problem in arid soils is the determination of the limits of toxicity of the various alkali salts. The author has already presented considerable data on this subject; but most of these results were obtained under laboratory conditions and with the use of pure salts. The combinations of salts used were not necessarily the combinations found in actual field conditions. It seemed desirable, therefore, to extend these studies to the field in order to determine the exact concentration of the various alkalis that prohibits growth in crops. A study of this kind also gives considerable data on the ratio of different salts found in alkali soils of the State.
