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.

1819. Elliott, L.F. (ed.). 1987. STEEP - Conservation concepts and accomplishments.. Washington State Univ. Publ., 662pp..
A compilation of 48 papers covering: tillage and plant maagement; erosion and runoff predictions; plant design; pest management; socio-economic; integrated systems; technology transfer for cropping systems; 22 technical notes. T: many

1219. Caplan, A.J.. 1986. Cost return and relative soil loss comparisons of alternative tillage systems.. MS Thesis.
Minimum tillage is less expensive than conventional. No-till is most expensive due to high chemical inputs. In the low precipitation zone, minimum till was 1.19 times less expenxive than conventional. Annual peas/wheat in high precip. zone was 1.5 times less expensive with min-till than conventional.

2052. Fox, C.P.. 1897. Idaho agriculture. ID Agr. Expt. Sta. Bull. #10.
Latah County, an important grain producer; also had apples, pears, prunes, berries. Potlatch district grew pears, nectarines, grapes. P shortages recognized on sandy river plain soils - recommended bonemeal or manure; distance to markets encouraged specialized farming.

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.

4465. Michalson, E.L. and I.A. Noteboom. 1966. Resource requirements, costs and expected returns for alternative crop and livestock enterprises, Palouse wheat-pea area.. WA Agr. Expt. Sta. Bull. #671.
A series of spread sheets. Shows wheat following green manure to be most profitable crop operation, and sow & 2 litter to be most profitable livestock operation. Dry pea seed with alfalfa is next most profitable crop. T: eg. Cost and returns for: wheat following grains, peas, green manure; pea seed with alfalfa; peas following alfalfa; lentils following grain; steer feeding; cow & clf; sow & 2 litter; ewe & lamb.

4474. Michalson, E.L.. 1964. Machinery costs and performance data for wheat-pea farms in the P. WA Agr. Expt. Sta. Circ. #437.
T: Estimated costs for trucks and tractors. Performance and cost data for tillage, harvesting implements.

4484. Michalson, E.L.. 1987. Tillage and cropping systems alternatives: Economics and productivity. p. 437-446.. IN: L.F. Elliott (ed.). STEEP - Conservation Concepts and Accomplishments. WSU Publications..
In most cases farmers would face cost increases by adopting conservation practices. This provides a rational for state/federal intervention to offset costs. The economic emphasis of soil conservation has shifted from the value of tons of soil to the farmer to the cost of tons of sediment to the public. T: Economic comparison of winter wheat/spring pea rotation with winter wheat/spring barley/spring pea rotation. Economic comparison of conventional vs. no-till on a 3000 acre summer fallow wheat farm in southwest Idaho. Estimated income above the variable costs, per yield levels.

4546. Moore, W.B. and S.F. Miller. 1987. Off-site economic impacts of soil erosion. p. 633-641.. IN: L.F. Elliott (ed.). STEEP - Conservation Concepts and Accomplishments. WSU Publications..
Per ton off-site costs for erosion are estimated at $2.81 - $5.43. On-site costs are estimated at $1.27 - $3.04 per ton. This results in an estimated total erosion cost range of $4.08 - $8.47 per ton of soil or $48.96 - $101.64 per acre with a 12 T/ac erosion rate. Off-site impacts are to: reservoir capacity/navigation; road systems; municipal/industrial water; hydroelectric power; fishery habitat; flood damage/flood control. Estimated costs would be higher if impacts to recreation, irrigation and effects of fertilizer/pesticide residues were included. T: Potential off-site erosion impacts. Economic estimates of off-site erosion impacts study.
