Eco L: Soil Diversity Introduction Soil is an ecological system consisting of inorganic minerals (sand‚ silt‚ clay‚ and nutrients)‚ pore spaces‚ water‚ gases‚ organic matter‚ living organisms‚ and plants (Thien‚ 2002). The soil is said to be stable structurally and chemically thus is considered an outstanding medium for soil organisms such as bacteria‚ fungi‚ protozoa‚ nematodes‚ arthropods‚ and earthworms. The potential habitats of these soil invertebrates are the spaces within the surface

These soil forming factors continue to affect soils even on "stable" landscapes. Materials are deposited on their surface‚ and materials are blown or washed away from the surface. Additions‚ removals‚ and alterations are slow or rapid‚ depending on climate‚ landscape position‚ and biological activity. Parent material. Few soils weather directly from the underlying rock . These "residual" soils have the same general chemistry as the original rocks. More commonly‚ soils form in materials that have

can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will

Soil Erosion And Conservation SOIL EROSION AND CONSERVATION Erosion Erosion is the removal of soil particles by the motion of wind or water. Soil erosion is one of the major concerns of modern agriculture throughout the world. The fallowing contributes to soil erosion: Misuse of land‚ Mismanagement of arable land‚ Indiscriminate felling of trees‚ Overgrazing‚ Poor soil and water management Erosion causes or Results in a: Decline in soil fertility‚ Water supply‚

Soil Conservation Matrix Review the three major types of soil degradation occurring in the environment. Briefly explain how each type of damage occurs. Causes Consequences Solutions Soil Erosion Water‚ wind‚ and people. (Miller‚2005 p.279) ●Soil erosion has two major harmful effects. One is loss of soil fertility through depletion of plant nutrients in topsoil. The other harmful effect occurs when eroded soil ends up as sediment in nearby surface waters‚ where it can pollute

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
