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

The role of bacteria in the soil Bacteria in the soil play key role in recycling matter in to useful nutrients which can be used by growing plants. This process of recycling matter in the soil by living organisms is called biogeochemical cycle. Bacteria are improving plants growth in other ways too‚ for example bacteria‚ such as Rhizobium‚ are in symbiotic relationship with the root system of some terrestrial plants. The most important elements‚ which allow terrestrial plants grow well‚ are

The section chosen for this investigation was the Urangan beach‚ adjacent to Churchill Street. Its main issue it faces is beach erosion. Erosion is caused by the slow or gradual wearing away of sand‚ and is especially common during storms‚ high tide and rough weather. 2.0 Methodology Primary data was gathered in the form of images taken at the beach and guest speakers (Acworth

Soil Porosity & Density Objective: To determine if the porosity of soil is related to the density. Hypothesis: I think that that the porosity of soil is related to the density because the higher the density of the sand the lower the porosity of the sand‚ which are both componets for the water to rise. Materials: • Sand and Loam samples • 2 large containers • Plastic cups • Water • Scale Procedure: Loam 1) The loam without the water was fresh ‚ it had different shades of black‚ and

‘landslide’ includes all varieties of mass movements of hill slopes and can be defined as the downward and outward movement of slope forming materials composed of rocks‚ soils‚ artificial fills or combination of all these materials along surfaces of separation by falling‚ sliding and flowing‚ either slowly or quickly from one place to another. Although the landslides are primarily associated with mountainous terrains‚ these can also occur in areas where an activity such as surface excavations for highways

Factors that Affect Soil Nutrients Nutrient availability can be influenced by several factors and these include: 1. Soil Ph: The relative concentration of the hydrogen irons and or hydroxyl irons may either increase or decrease nutrient availability. 2. The Presence of Other Nutrients: The essence of the various mineral salts will either increase or decrease the other mineral salts in the soil. 3. Leaching: This encourages the draining of mineral salts from the topsoil to subsoil thereby depriving
