What impacts would differences in soil bulk density have on growing a crop in a clayey soil? 2. how would the bulk density of the a horizon and b horizon in a texture contrast change compared to a gradational soil? . if animals are placed onto medium clay soils which have become waterlogged, what might happer to the soil bulk density 4. what are the main components of soil that are related to development of soil structure? 5. what are some of the benefits of conservation agriculture in terms of the impacts on soil structure and bulk density 6. how would you calculate the weight of soil in an area (c. g. i hectare) using information on soil bulk density?
