643. Baker, V.W. and I.P. Swanson. 1962. Economic effects of a grass-legume rotation in Palouse wheat-pea area.. WA Agr. Expt. Sta. Circular #183.
Farms using a grass-legume rotation show important economic advantages over other farms in comparison of 5 year data from 3 pairs of Palouse farms. T: Amount of cropland by type of crop. Average annual crop production. Cost inputs and income per cropland acre. Calculated erosion losses.

2200. Goldstein, W.A. and Young, D.L.. 1987. An agronomic and economic comparison of a conventional and a low-input cropping system in the Palouse.. Amer. J. Alternative Agriculture 2(2):51-56.
Describes the results of Goldstein's work with the pea-medic/medic/wheat rotation in comparison with a wheat/barley/wheat/pea rotation. Variable costs for PALS were 44% of those in the conventional system. The conventional system generated higher gross returns, and higher net returns under subsidized prices, while the PALS was economically attractive at market prices.

3570. Kent, R.L.. 1957. Conservation crop rotations in the PNW.. J. Soil Water Conservation, 12(6): 269.
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.

7786. Engel, R., L.E. Welty, R. Lockerman, J. Bergman, G. Kushnak, L. Prestbye, and J. Sims. 1987. Annual legumes and cereal grain rotations in Montana.. Montana AgResearch 4(3):1-4.
Montana researchers examined the performance of several grain legumes (dry pea, chickpea, lentil) and their effect on a subsequent barley crop. Dry pea production was the highest. A subsequent barley crop rsponded to added N fertilizer at three out of six sites. Barley yields following legumes were generally equal to or greater than yields following fallow. The annual legumes contributed to soil N and reduced the fertilizer N needed to reach maximum yield by 40-55 lb N/ac when compared to recrop barley. This translated into savings of $10-14/ac for fertilizer N.
