26. Lerch, R.N., K.A. Barbarick, D.G. Westfall, R.H. Follett, T.M. McBride, and W.F. Owen. 1990. Sustainable rates of sewage sludge for dryland winter wheat production. 2. Production and income.. J. Production Agric. 3:66-71.
A sewage sludge application rate of 3 T/ac on hard red winter wheat increased gross income by an average of $45/ac/year compared to wheat grown with the typical 50-60 lb fertilizer N/ac. This was primarily due to premiums paid for higher grain protein. Grain levels of P an Zn were increased by sludge application, while levels of Cd, Ni, and Pb have remained low.

3633. Klemgard, J.G. and G.F. Cadisch. 1931. Cost of wheat production by power methods of farming, 1919-1929.. WA Agr. Expt. Sta. Bull. #255.
Costs for an 11 yr period are analyzed: rent 39%; labor 11.7%; depreciation 10.5%; gas and oil 8.9%; grain bags 7.3%; repairs 6.5%; interest 6.0%; seed 4.2%; food 2.7%; taxes 1.5%; insurance 1.2%. Some suggestions for lower production costs are: retain farm machinery longer; handle bulk grain rather than sacked; seek custom work; buy supplies wholesale; reduce or avoid permanent improvements or capital outlays; keep machinery in good repair; till with proper soil moisture; purchase supplies with cash. T: Total expenditures and their distribution in producing wheat under power methods, 1919-1929. Cost elements in wheat production and their distribution. Distribution of costs per bushel of producing wheat under power.

4827. Nelson, E.. 1908. Dry farming in Idaho. ID Agr. Expt. Sta. Bull. #62.
Caldwell, ID - better sites yield 30-40 bu/ac wheat, even 60; alfalfa - several cuttings; drier sites yield 20-30 bu/ac; in Utah, 1" of rain stored in soil produces 2.5 bu wheat; summerfallow necessary; eastern WA - late spring plowing with early disking and harrowing is effective weed control; "slicker" - homemade tool in Columbia Basin to kill weeds; Subsurface packer - after plowing, increased yields in Columbia Basin 25%. Idaho soils - short on N and humus; alternate crop possibilities: milo, sorghum, field peas, alfalfa, grass; also spring emer (speltz), hulled wheat (adapted to arid conditions); WW vs. SW has 4-5 bu/ac yield advantage.
