Good % of pea N is from soil; best to plow under right after flowering; Melrose contributed 278 lb/ac of vine N; winter peas produced slightly more biomass than spring peas, but fall peas can be plowed 2 weeks earlier; spring peas accumulated 70 lb N/ac more than winter peas; variable cost of WW-SB-SF = $63/ac, uses 120 lb N/ac; for WW-SB-pea GM = $59/ac, with only 40 lb N/ac; must consider intangible benifits; recommended green manure crop every 3-5 years. T: organic matter yield, nitrogen content, costs.

835. Bezdicek, D.F.. 1990 Jan.. Crop rotation studies. presentation at STEEP Annual Review, Moscow, ID.
Several studies were described in which different legume green manures were grown before winter wheat and treated with different residue management. Wheat yields were consistently depressed following chemically-killed legumes in the first study, but not in the second. Under chemical kill, there was a 40 bu/ac wheat yield response to soil fumigation. Part of the fumigation response appeared to be higher available N. Also, it appeared that chemical kill may be increasing N mineralization. Results are being prepared for publication.

995. Bonnett, R.K. and H.W. Hulbert. 1922. Sweet clover. Id Agr. Expt. Sta. Circular #22.
More drought tolerant than red clover or alfalfa; biennial white is best for Idaho; value for hay and soil improvement; white yields 1T more hay than yellow; quality of hay better from yellow; well adapted to alkali soils; 15 lb/ac seeding; early seeding best, without nurse crop in drier areas; peas are best nurse crop; as a green manure, is expensive, decay is slow, depletes soil moisture; need to summerfallow after SC in the drier areas.

Sweetclover maintained OM levels, slight loss in W-P; N fertilizer reduced OM losses where straw was removed.

1765. Dunbar, B. and D. Nielsen. 1987. White lupins as a rotation alternative with winter wheat in conservation tillage systems.. IN: J.F. Power(ed.) The role of legumes in conservation tillage systems.
Tested white lupin adaptability to irrigated and non-irrigated conditions in Colorado. Screened the crop for a number of herbicides, none of which was entirely satisfactory. All damaged or killed the lupins at rates needed to control weeds. Non-irrigated yields were about 30 bu/ac, up to 50 bu/ac with full irrigation. Lupins did not appear to utilize stored soil water at lower depths.
