After reading this article you will learn about:- 1. Impact of Soil Pollutants on Soil Biota/Microbes 2. Impacts of Soil Pollutants on Vegetation 3. Problem in Tropics. Impact of Soil Pollutants on Soil Biota/Microbes: Soil pollutants like metals, pesticides, organic substances showed detrimental impacts on soil fauna, flora and other microbes. This is common event in contaminated soil. Soil microbes [...]
Physicochemical properties of soil include soil texture, water, air, inorganic chemicals, and organic matter. The biological factors of soil are soil flora and fauna. Mechanical composition (texture) of soil is determined on the basis of size of soil particles i.e. sand, silt and clay particles (Table 30.1). However, the ratio of soil particles governs the porosity (pore size of soil), [...]
In this article we will discuss about the factors that govern the rate of decomposition of organic matter. Also learn about the microorganisms that are associated with organic matter decomposition. (i) Litter Quality: Structural and chemical properties of litter make up its quality. However, it is less specific term reflecting decomposition rate. Dubey and Pandey (1996) have recorded the higher [...]
