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.
