compresses under its own weight due to the loss the force of buoyancy. During primary subsidence, the volume of the organic component decreases, but the mass of the organics remains the same. Secondary subsidence is caused by a combination of oxidation and shrinkage. The mass and volume of the organics decreases during secondary subsidence (Ewing and Vepraskas, 2006, p. 121-122). Being able to differentiate between the two different kinds of subsidence in marshes allows for more precise methods of measurement by scientists. Primary subsidence happens before secondary subsidence, and secondary subsidence typically only occurs in the upper portion of the soil stratum, the part exposed to air. Primary subsidence reduces the volume of the soil, while the mass of the sample stays the same. Meanwhile secondary subsidence reduces the volume of the soil and reduces the mass of the soil.

Erosion is destruction on the rangeland from wind, water, cattle, and other natural agents. The process where the Earth gets worn down and removes material from the top of the soil. Erosion has been dated back to Plato and Aristotle (Montgomery et al 2007). There are many types of erosion, water erosion, sheet erosion, gravitational erosion, and wind erosion (Zonghu et al 1991). Water erosion is mainly in fields, where rilling would take place (Evan and Morgan 1974). Water erosion usually happens due to the lack of cover on the rangelands, and heavy rainfall will destroy plants, and even move the soil. Wind erosion is the most common type of erosion. One of the greatest problems in the United State is the wind shifting the soil surface (Pierson et al 1961). Livestock such as cattle (Bos taurus) also pose a threat to the landscape. Hart (1949) did a study on dairy farms, and found excessive gully erosion. Land with erosion losses the ability to hold water for the soil (Gifford and Whitehead 1982; Boardman and Mortlock 1993) while also losing key nutrients such as

The proposed development is located near to a public drainage reserve where cannot be develop on this site. It is a commercial building with four storieys. The total tenant area is about 5485m2. It will operate with multiple uses including a café, pharmacy, medical Centre and a lot of commercial units

Some of the water left underground may leak to the surface (through cracks and fractures) contaminating natural resources and water bodies.

Round 4 = The missing species in this ecosystem is lichens. Without lichens soil would not be created and the plants would suffer because the proper nutrients aren’t getting to them to grow.

Drainage issues can be very complex and sometimes require a topographic survey to resolve. Topographic surveys include information on the features of the property that affect the flow of water including trees, slopes, mounds, structures and ditches. They also measure the height and depth of these features and the contour of the land. The information in a topographic survey is critical to landscape design elements that will alter the grade of your property.

One of the main causes for Desertification is something named Erosion. The definition for Erosion is when the

Site Work: Rains turn a construction site into a gigantic mud hole in most cases as dust is predominantly present on any construction site. Mud hinders access to the site by all building trades and prevents or slows down general earthwork (grading, trenching, and backfilling activities), paving, and foundation work. Both foot and vehicle traffic may be restricted, and compacted gravel or rock is often used in roadways to establish a firm base. The site should be properly graded to ensure positive drainage away from the structure and to prevent water collection points. If not considered during the planning phase,

The pavement of soil in farmlands results in a loss of nutrients in the soil. This means that the soil is now unable to be used.

The concept of the conservation of soil takes into account, the strategies for preventing the soil from getting eroded and preventing it from losing its fertility due to an adverse alteration in its chemical composition. Here are some ways to

Practice of soil science includes, but is not limited to investigating and evaluating the interactions between water, soil minerals, plants and other living organisms that are used to prepare soil scientists’ reports for; subsurface ground absorption systems, including infiltration galleries; land application of residuals such as sludge, septage, and other wastes; spray irrigation of wastewater; soil remediation at conventional rates; land application of agricultural products; processing residues, bioremediation, and volatilization; soil erodibility and sedimentation; and identification of hydric soil and redoximorphic features.
