2984. Jacklin, A.W.. 1940. Annual Agronomy Report. North Idaho Area. USDA - SCS, Moscow, ID.
Sweetclover well suited as a soil building crop; best to plant with a grass to reduce erosion, reducing "burning" of first grain crop, improve quality of forage; have tried slender wheat grass, blue and Canada wild type; still looking for a good species; gypsum increased tonnage of tops, shortened tap root depth. T: yield, crop performance.

3481. Kaiser, V.G. and A.W. Jacklin. 1939. Annual progress report for field test "effect of cropping systems".. USDA-SCS.
Better sweetclover stands when seeded alone or with grass; peas better than cereals; hi (>10 lb/ac) seeding rate leads to better stands; best seeding date April 10-May 7; more weeds in second year when grown with companion crop; sweetclover/grass mix gave greater wheat yield increase than SC alone, also had less erosion; excellent thorough study. T: Yield, erosion X agronomic management.
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.
6978. USDA Soil Conservation Service. 1938. Study of erosion controlling forage plants.. USDA - SCS, Pullman, WA.
Promising new legumes - milk vetch species, big headed clover, flat pea, siberian alfalfa, black medic, trailing birdsfoot, sanfoin, lupin, Montana goldenpea, perennial vetch. Yellow sweetclover was superior to white under drought conditions; dwarf varieties recommended in drier areas; clipping sweetclover reduced vigor, hay yield and total N per acre; Ladak the best alfalfa variety for the region.
