Soil degradation refers to the decline in quantity and quality of soil. Degradation of soil is done by erosion (wind and water)‚ biological degradation‚ physical degradation (referring to the over loss of structure and changes in permeability) and chemical degradation‚ this refers to acidification‚ declining fertility‚ changes in pH levels‚ salinization and chemical toxicity. Soil degradation affects not only the environment but also the economy as well as people. The effect that soil degradation

Soil FRQ A) One chemical soil test we could do is a pH level test so we are able to tell what crops can grow in what areas. Other chemical tests include salinity‚ organic content (humus)‚ or the iron exchange capacity. One Physical Soil test we can do is pick up a handful of it and rub it together with our fingers to tell if it’s a soil heavy in clay‚ silt‚ or sand. Other physical tests include water-holding capacity porosity‚ moisture content‚ soil structure‚ or color. By completing these tests

SOILS IN INDIA Soil is the uppermost layer of Earth’s crust. Soil is the medium in which plants grow and thus it supports the lives on earth. How soils are formed? Soils are formed due to the weathering of rocks. WHAT IS SOIL? Soil is the thin layer of loose mixture of small rock particles and rotting organic matter that covers much of the world’s land surface. SOIL FORMATION Soil formation is a very long process. It begins with the weathering of rocks into small fragments

Meredith Hamilton Biology- Westover September 30‚ 2011 Abstract The question of this study pertained to the amount of vegetation that was occurring on each of the succession plot’s ground floor. There are three successional plots in Winthrop University’s wooded areas‚ the oldest was created in 1989 the second was created in 1994 and the youngest plot was created in 1999. For the hypothesis to be tested‚ there were soil PH meters to test the amount
