Below A lies theB horizon. In mature soils this layer is characterized by an accumulation ofclay(small particles less than 0.002 mm [0.00008 inch] in diameter) that has either been deposited out of percolating waters or precipitated by chemical processes involving dissolved products of weathering....
They usually have a high cation exchange capacity, and can combine with various chemical substances (base exchange) such as calcium, sodium, potassium and ammonia; in this way plant nutrients can be held in the soil. Grouping or flocculation of the particles is very important in making clay s...

However, information on the effects of organic–mineral association on the composition of clay minerals is very limited. There is greater complexation capacity for soil organic matter with smectite and vermiculite that have smaller size and larger specific surface area than other minerals (Balabane ...
(3) The ageing process can impact the microplastics mobility, adsorption capacity, and the release of the associated contaminants derived from the microplastics. The release of endogenous organics phthalate esters from aged microplastics could reach 50.3-6660ng/g, and that of heavy metal Pb2+ reach...

Inoculation: This method is used for the survival of a microorganism and its remediation capacity. Inoculation method affects rhizosphere, soil, colonization, and plant (Afzal, 2010;Afzal et al., 2012, 2013). Basically four methods of inoculation are reported (Weyens et al., 2009a, b): ...
will reflect the drought tolerance of plants and soil microbes, rooting responses (depth) and water-holding capacity of soil. Collectively, these factors interrelate to produce a response space that may range from suppressed C uptake through N limitation (Heimann & Reichstein, 2008) and declined ...
