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

Microbial analysis of soil‚ of top layer from selected sites of Area near Dahisar River Saika N. Esani University of Mumbai (Email – saikae@ymail.com) Abstract: soil samples were collected fortnightly from area near Dahisar River‚ A river in suburb of Mumbai. laboratory analysis started from July 2010 to September 2010. Total bacterial and fungal count were estimated by standard spread plate isolation. Isolated bacteria were subject to colony characterization and were estimated by their

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

University’s Successional Plot’s Soil P.H. 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

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

Next to water and air‚ soil is most essential to our very existence on the earth. Soils are the basis of support for most life‚ and a source of nutrients for marine life and fresh water. As a natural resource‚ soil is of immense value to man. In the agricultural orient the distribution and density of population have conformed to the persisting patterns of soil fertility and productivity. Soil is basically broken-down rock materials and consists of decomposed rock debris and decayed organic
