Overview

Excerpt from Alkali Studies, II The Experiment Stations are supported for the purpose of scientific research in the problems of agriculture and they are located in different states in order that each Station may study, at close range, the conditions of the region that sur rounds it. From its location the chief problem of the W'yo ming Station has been given to it by nature, the study of ari dity, and as fast as possible the work of the Station has been concentrated on this subject. The chief difficulties in the way of agriculture in the arid region are two, the insufficient supply of water and the accumulation of soluble salts, known as alkali. The second of the these is a consequence of the first. Where watering is done by rain, pure water is added to the soil and drained off underneath, carrying with it the soluble salts of the soil. In irrigation, water containing salts is added to the soil and pure water evaporated from the surface. It was shown in Bulletin No. 24 that half a ton of alkali was added to each acre of the Sheridan Farm every year by irrigation and the land became completely useless until it was drained.
