2232. Grabe, D., F. Bolton, C. Garbacik, and J. DeNoma. 1989. Response of winter wheat to yield-enhancing agents.. Columbia Basin Agr. Research Spec. Report 840.
Tested a number of non-traditional products, including YEA!, Amplify-D, Car-Dak, Bio-Mag seed treat, seed moisturing. YEA! had a small but significant effect on seedling growth, while the other products did not. No yield responses were observed. Seed moisturizing with various pressure treatments did not appear to have any field benefits.
3356. Jain, J.M., G. Narayanasamy, M.C. Sarkar and M.N. Datta. 1980. An evaluation of nitrification retardation property of Citrullus colosynthis.. J. Indian Soc. Soil Sci., 28(4):480-484.
An evaluation of nitrification retardation property of Citrullus colosynthis cake and its influence on yield and N uptake by wheat. Citrullus colosynthis oilcake was tested as nitrification retarder under laboratory and greenhouse conditions. The same showed NH4-N conservation when applied at the rate of 5 and 10% by weight of urea. Higher rate (20%) of the cake resulted in NO2-N accumulation leading to lower N recovery by wheat.
3770. Krchnavy, Z. and M. Ambrozova. 1979. The function of the biological component of soil in the no-tillage monoculture wheat-growing system.. Rostlina Vyroba, 25(9):893-900.
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.
9240. Alessi, J. and J.F. Power. 1980. Effects of banded and residual fertilizer phosphorus on dryland spring wheat yield in the Northern Plains.. Soil Sci. Soc. Amer. J. 44:792-796..
Although phosphate fertilizers are commonly applied either by surface broadcasting or banding with the seed to dryland spring wheat, data are limited on the residual effects of previous fertilization on plant growth and drought periods during the growing season. Therefore, the residual effects of P fertilization on spring wheat grown on Parshall fine sandy loam were determined in a field study at Mandan, North Dakota.
10652. Chaney, D.. 1991. Marine by-products as fertilizers.. Components, UC Sustainable Agr. Program, Davis, CA (Winter 1991), p. 12-13.
Research and field experience indicate that marine by-products can improve soil structure, enhance soil microbial activity, and promote plant growth. Current processing and distribution costs presently limit their use. Fish waste, fish emulsion, shellfish waste, and seaweed are the major classes of materials. Research has established that seaweed supplies some plant nutrients (especially micronutrients), enhances plant growth, and improves soil tilth.
