GRICULTURE in eastern Washington and particularly in A the Palouse region has developed around a wheat-pea or a wheat-summerfallow rotation system. Since neither wheat nor peas are effective in controlling erosion, it is desirable to introduce a sod crop into the farming program bo aid in reducing the erosion hazard and to restore or maintain the soil fertility. A continuing 5-year project was established having the following objectives: 1. Development of a practical method of establishing definite quantities of grass with sweetclover for maximum erosion control; 2. A study of the relative contributions of sweetclover and grass tops and roots to total production in mixtures; 3 . The determination of the correct ratio of sweetclover to grass for maximum soil building; and 4. The maintenance of a satisfactory level of grain production in the rotation. This paper is a report of the :yield data for the first 2 years of the study. .
