Show PART III IRRIGATION POTENTIAL The alluvial soils in the river or stream valleys are high in or- ganic matter and are inherently fertile. There is a notable variation in their source, textural composition, profile development, permeability, and drainability. With the exception of small localized areas, they are free from harmful accumulations of salt and alkali. Most have good natu- ral drainage provided by coarse-textured soil over gravelly subsoil and a moderate slope. The depth and texture of the soil, water table levels, size and shape of tracts, and the amount of rock on the surface usually determine the suitability of alluvial lands for irrigated agriculture. Broader expanses of potentially irrigable land occur in more remote positions on intervening ridges and benchlands separating the upper stream valleys. Many of these lands lie above limiting elevations for delivery of water from adjacent streams by gravity and therefore require higher costs for irrigation development. Moderately shallow residual or aeolian soils on sedimentary rock and moderately to steeply rolling ter- rain are characteristic of these lands. Shallow lands overlying a bar- rier substratum will have a high drainage requirement when developed for irrigation. Typical reddish-brown aeolian soils on undulating topography being dry farmed in the San Juan-Colorado Subregion. Planned Federal irrigation project will provide dependable water supply for these lands for increased production of diversified crops. |
