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.
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.
