3298. Burt, O.R. and M.S. Stauber. 1989. Dryland cropping decision theory with application to saline seep control.. J. Production Agr. 2:47-57.
A model for decision making in a flex-crop system is presented, based on plant available soil water at seeding, previous land use, and economic return. The strategy can be used for winter or spring wheat.

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

2304. Grilley, W.. 1990. Wheat production costs outlined.. Growers Guide, January 1990, p. B7.
The average cost of producing a bushel of wheat in Eastern Oregon under a wheat-fallow system. An average yield of 42 bu/ac was used. The 1989 costs was $4.55/bu. The total estimated production cost for the 1989-90 crop is $190.01 per planted acre, using moldboard plow tillage. Total wheat acreage for the Columbia Plateau was estimated at 514,500 acres harvested.

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.

3752. Kraten, S.L.. 1979. A preliminary examination of the economic performance and energy intensiveness of organic and conventional small grain farms in the Northwest.. M.A. Thesis, Dept. of Agr. Econ., WSU, Pullman, WA. 158pp..
Economic and energy profiles from six organic farms were compared with similar conventional farms. The conventional farms produced 2% more crop value per acre than the organic farms. The organic farms had 22.4% higher net return due to lower variable costs. The conventional farms were 52.6% more energy intensive per dollar value of output than the organic farms. The organic farms yielded 39.9 bu/ac and conventional farms yielded 35.2 bu/ac. T: Average returns and energy use for organic and conventional farms. Cost, returns, and energy use by crop.

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.

Describes one model for organizing and mobilizing scientific resources to address the highly complex and costly problem of soil erosion in the PNW. With a USDA grant to the Agr. Expt. Sta.'s in WA, OR and ID, plus supplementary state and federal funds, STEEP awards intermediate-term grants (15yr) for research in 5 areas: tillage and plant management, plant design, erosion and run-off predictions, pest management, and socioeconomics of erosion control. Most projects require collaboration across disciplines, and, sometimes, a╚ross state boundaries. Results (after 6 yrs) indicate STEEP model might be applicable to other regions and problems.
