2908. Idaho Agr. Expt. Sta.. 1944. Annual Report. ID Agr. Expt. Sta. Bull. #255.
Legumes and grasses are a good choice for eroded soils; had decent yields and economic returns when compared to grain production on these sites.

2784. Hulbert, H.W.. 1927. Sweetclover.. ID Agr. Expt. Sta. Bull. #147.
Biennial white is best forage, biennial yellow is too short; can handle alkaline soils; earlier seeding is best; 15 lb/ac seed, or 10 lb/ac in drier areas; nurse crop is risky, peas may be best; 3/4 T/ac hay first season, 2-3 T/ac second year; best used for pasture and soil improvement; can be grazed early spring through fall; improves soil quality, breaks up subsoil; sweetclover as green manure too expensive for dry areas; one system used is WW/SC planted in fall (unscarified seed) at 5 lb/ac; after wheat harvest, pastured SC into late fall; field is spring plowed and SF; then WW again, this raised WW yields 3-8 bu/ac; might try with Hubam (annual) SC.

4377. McKay, H.C. and W.A. Moss. 1949. High protein wheat with conservation farming.. U. of Idaho Extension Bull. #181.
Emphasize need for legume - grass rotation to maintain soil productivity. Suggest a 7 yr sweet clover rotation or a 9 yr alfalfa rotation. Yellow sweet clover plus mountain bromegrass or slender wheatgrass; Ladak alfalfa plus smooth brome and big bluegrass (high rainfall) or crested wheatgrass (low rainfall); early spring seeding recommended without nurse crop; methods of establishment, plow sweetclover at 12-22" height; use sweetclover as a surface mulch to prevent erosion. T: soil moisture and sweetclover growth; wheat after sweetclover; yield and protein.

6629. Stark, R.H., J.L. Toers and A.L. Hafenrichter. 1946. Grasses and cultural methods for reseeding abandoned farm lands in the wheat/fallow zone of the intermountain West.. ID Agr. Expt. Sta. Bull. #267.
Wheat/fallow zone of intermountain west; cheatgrass takes over abandoned land, perennials can't re-establish; tried summerfallow, duckfoot cultivator, burning, and no preparation; summerfallow gave best results; fall seeding best; recommend planting of several grasses in different blocks to extend grazing. T: methods, yields, species, accessions, bibliography.
