Book Description

Excerpt from Irrigated Crop Rotations in Western South Dakota The native vegetation consisted mainly of a buffalo grass on the better soil types and a rather scattered growth of western wheat gr'ass on the poorer lands. The soil on the Belle Fourche Field Station of the Bureau of Plant Industry, United States Department of Agriculture, consists largely of a heavy gunibo, which is considered less desirable than that generally under cultivation on the project. This is particularly true of field A, where the irrigated rotation experiments herein reported are located. When climatic conditions are favorable and' the land is properly cultivated, good yields are usually harvested; but owing to the refractory nature of the soil special care must be taken when it is cultivated if satisfactory results are to be expected. The addition of humus has been found to improve materially the structure of such soils. Cultural operations can be performed only when the moisture content of the soil is well below the field capacity. It is impracticable to plow, cultivate, or plant when the soil is too wet. Consequently, farmers often find it impracticable to perform these operations at the most suitable or convenient season, and serious delays may occur during periods when frequent showers are experienced.
