Agriculture: Soil Microbiology


Soil Microbiology Until fairly recently, the living soil has been considered as a functional black box that is intrinsically too difficult to be unravelled into its core components. However, this concept has changed with the advent of the modern methodologies. The intricacies of microbial life in soil has been impacted by the advanced, mainly molecular-based, approaches that have been unleashed on the soil habitat in recent years.
Soil MicrobiologyThe application of molecular and other advanced methods (cultivation-independent analyses) has provided exciting new insights into microbial life in soil. Soil is an extremely diverse and complex habitat containing many microsites and gradients that form a range of different biogeochemical interfaces. Depending on the proportion of sand, silt and clay, the surface area in soil can vary from 11 cm2 up to 8 million cm2 per gram of soil read more.
The aggregates formed by minerals, soil organic matter, fungal hyphae, roots and plant debris offer a range of potential niches for microorganisms with different lifestyles. The architecture of the soil pore network essentially defines the habitat colonized by the microorganisms and the pore space strongly influences the nature and extent of the interactions between the organisms inhabiting the soil.

The heterogeneous physical structure of soil affects the spatial distribution of water, oxygen and nutrients, which in turn influences the composition and activity of the microbial communities themselves. As an example, the spatial distribution of bacteria in topsoil and subsoil was found to be different, but lateral variations in spatial distributions are also likely to occur. Soil is the surface layer of earth on which the human civilization depends for its existence. Actually soil represents the loose upper crust of the earth surface distinctly different from the underlying bed rock.
Its depth, colour, composition vary from place to place, but all soils are common in consisting of inorganic (mineral) and organic matter, water, and gaseous phases. Every soil is made up of a succession of layers, collectively known as soil-profile, reaching down to the parent material. The soil-profile consists of two or more horizontal layers, called horizons. The soil horizon may vary in thickness, mineral composition, and structure; they are indicated by the letter A1, A2, A3, B1, B2, B3, C1, etc. A1 horizon is the uppermost or surface layer of the soil and its fertility level is very important from viewpoint of an agriculturist.
Soil fertility depends not only on the presence of inorganic and organic substances, but also on the

Begin soil preparation by removing old plant supports, plastic mulches, excessive vegetative residues and other debris from the garden area several weeks before planting to allow the soil to dry out. The amount of plant residue that may be turned under...

- Nutrients Availability At Different Ph Value
The pH value measures the ratio of H+ ions to OH-base ions in the soil. If the soil solution has more H+, the soil is acidic. If the OH-dominates, the soil is alkaline. The equal balance between them is neutral and its value 7.0. The soil pH value interacts...
