Activity 1 – Water Holding Capacity & Capillary Action of Soil 1. Grain size and the amount of air space between particles. 2. Water-holding capacity determines the amount of water a soil is capable of holding. Since water is a necessity of any agricultural endeavor it is important for a soil to have a good water holding capacity. 3. We’d add humus because it has the highest water-holding capacity. 4. It would benefit plants in a dry climate because it could easily take groundwater

conservation of natural resources conservation of natural resources‚ the wise use of the earth’s resources by humanity. The term conservation came into use in the late 19th cent. and referred to the management‚ mainly for economic reasons‚ of such valuable natural resources as timber‚ fish‚ game‚ topsoil‚ pastureland‚ and minerals‚ and also to the preservation of forests‚ wildlife‚ parkland‚ wilderness‚ and watershed areas. In recent years the science of ecology has clarified the workings of the biosphere;

Agricultural Land Conservation The issues of land distribution and land conservation in agriculture attract more and more attention‚ especially when the expansion of cropland is hitting a limit since much more land is conserved for environmental purposes. Soil erosion is devastating the topsoil of land as chemical fertilizers are used to increase output within a limited amount of land. At the same time‚ livestock production expands at an ever-growing speed‚ worsening the land use situation.

of the centrifuge increases. The G-force increases as the speed of the centrifuge increases. Which is likely the best speed to separate the components of this soil sample? Why? The best speed to seperate the components of this soil sample would be 5000 rpm because there are only two layers so the soil is more separate in that speed. Describe in which layers you are likely to find the organic matter‚ gravel‚ sand‚ silt‚ and clay at the following speeds:

The first is labelled as Valley A‚ and was obtained from a field which has been known to be uncultivated for 10 years in the valley. Valley B was obtained from a domestic garden‚ under a Magnolia tree in the same region. At times when a third sample was tested‚ the source will be indicated. Soil texture

Article Summary Effects of earthworms on soil Earthworm is the common name for the largest members of Oligochaeta in the phylum Annelida. They combine bilateral symmetry and corresponding external and internal segmentation. This phylum consists of more than 17‚000 modern species of worms including earthworms‚ ragworms‚ and leeches. They are found in marine environments from tidal zones to hydrothermal vents‚ in fresh water‚ and in most terrestrial environments. They generally do not occur
