935. Bolton, F.E.. 1990. Starter fertilizer trials - no-til.. Sherman Station Field Days, OSU, Moro, OR.
The use of starter fertilizer, including N, P, and S in various combinations, was examined for no-till winter wheat and winter barley. Variable results occurred, but yield increased were measured in most years. About 3 out of 5 times, the increase was economically feasible. Overall yields under no-till averaged equal to or slightly lower than conventional tillage.

Liquid starter fertilizer on winter wheat and barley in no-till plantings.

Studied the interaction of organic manuring (cattle slurry, catch-crop for green manuring, and combination) and a five- to eight-year monoculture of winter wheat sown in uncultivated soil. Results indicate that for almost all microbial indices, particularly those concerning the conversion of carbonaceous substances, ammonification and phosphate activity, higher values can be observed in the soil left without ploughing than in the cultivated soil. Nitrification decreased. The combination of the catch crop and sowing in uncultivated soil encourages the general biological activity more intensively than in the case of ploughed soil.

Fertilizer experiments with no-till annual cropped small grains were conducted in 1983-84 near Pilot Rock and Kent, Oregon. Summary and recommendations: 1) No-till annual cropping is feasible on shallow (<36 in deep) soils that usually fill with water the first winter after grain harvest.; 2) Uniform distribution of chaff and straw when harvesting is important; 3) Proper herbicides are needed; 4) Use a drill capable of seeding through standing crop residue, banding fertilizer 2-3 inches below the seed; 5) The optimum fertilizer rate is usually 150% of the optimum rate for grain after fallow; 6) Banding fertilizer 2 or 3 inches below the seed is best.

9617. Grant, C.A., E.H. Stobbe and G.J. Racz. 1984. The effect of N and P fertilization on winter survival of winter wheat under zero-tilled and conventionally tilled management.. Can. J. Soil Science 64:293-296..
A preliminary field study was conducted to investigate the influence of fall applications of nitrogen and phosphorus on winter survival of winter wheat on zero-tilled and conventionally tilled land. Nitrogen fertilization tended to decrease winter survival while phosphorus fertilization tended to increase survival. A N-P interaction was observed, with the derease in survival in response to added N being more evident in the absense of applied P. Balanced N-P fertilization may therefore result in highest winter survival in both conventionally tilled and zero-tilled winter wheat.
