661. Barnes, O.K. and D.W. Bohmont. 1958. Effect of cropping practices on water intake rates in the northern Great Plains.. WY Agr. Expt. Sta. Bulletin 358.
The rate of water absorbed by the soil was evaluated on bare fallow, trashy fallow, and grassland. Total absorbed water in one hour was 1.55, 2.80, and 2.11 inches for the respective covers. The water intake rate at one hour was 0.3 in/hr for bare fallow and 2.26 in/hr for trashy fallow. Water intake rates associated with other tillage practices are also presented in this bulletin.
816. Bezdicek, D.. no date. (Influence of residual soil N on N2 fixation; N2 fixation of chickpeas). unpublished.
High levels of residual soil N decreased N2 fixation. There was a negative correlation between the fraction of plant N derived from N2 fixation and total mineralizable N and KCl extractable N. N2 fixation was reduced by about 2.8 kg/ha for each kg/ha of available soil N. Seed yield response from inoculation ranged from 5-70% and was negatively correlated with available soil N. Residual soil moisture in July was greatestfor large seeded legumes > forage legumes > winter wheat. T: N fixation in chickpeas.

Stubble increased snowcatch and wheat yields; fall chiseling increased water infiltration and wheat yields; burning straw decreased yields after 6 yrs; row seeding a response up to 50 lb/ac N; research done at Tetonia; early fall seeding gave highest potential yield, but more disease and weed problems; annual cropping is possible when stored soil moisture exceeds 3 1/3 feet. T: tillage X moisture, yields
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.
