Average base yields for the Yuma Valley area are
contained In Table 3-75. Crop damage functions were
estimated by comparing effective values of soU
ssturation extract conductivities for the three soU
types (Tabte 3-39) to the declination percentages. in
Table 3-1.

llCrops under these columns are those assumed to lead
in the double cropping rotation.

Leaching, land leveling, special bedding, and
irrigation frequencies were selected by the model as
