Experimental data and observations indicate that crop rotations with grass and legumes is needed in the wheat-pea area. Also of importance are strip croping, contour operation, stubble mulching, early seeding of winter wheat. T: comparison of OM, water loss, soil loss from virgin land and crop land.

Alfalfa was not successful as a legume in rotation with cereals over 16 years. Oat yields following 2 years alfalfa were 14.7 bu/ac compared to 21.5 following corn. Alfalfa greatly depleted soil moisture.

Describes 3 basic rotations for the region: 1) grass/alfalfa - no more than 2 yr grain (Class IV land, precip. >17"); 2) grain - fallow - various rotations with alfalfa/grass or sweetclover depending on precip. (12-17"); 3) permanent grass/legume, with no more than 2 yr grain (precip 9-12", Class IV land); lists adapted grass and legume varieties; describes use of rotary hoe and skew treader for weed control. T: grass varieties.
