Soil agrobiodiversity
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 8
Abstract
Soil is one of the most diverse habitats on earth and contains the most diverse assemblages of living organisms. Soil is the central organizing entity in terrestrial ecosystems and possess extremely diverse. It is physically and chemically complex, with micro- and macro-aggregates embedded within a solid, liquid and gaseous matrix. Recent advances in molecular techniques in systematic have provided opportunities for the study of soil biodiversity. Agriculture is undoubtedly one of the main driving forces which influence biodiversity in the world. Soil biodiversity refers to all organisms living in the soil, and therefore soil environment is one of the most complex biological communities on earth, home to an even larger share of biodiversity than tropical forests. Functional diversity of microbial populations in soil may be determined by either expression of different enzymes or diversity of nucleic acids within cells, the latter also reflecting the specific enzymatic processes operating in the cells. The absolute number of organisms under a footprint will probably range between 109 and 1014 individuals.
