Soils structure describes the arrangement of the solid parts of the soils and the pore spaces located between them (Marshall and Holmes 1979) soil structure is determined by how individual soil aggregates clumps or bind together to form aggregate, and there fore the arrangement of soil pores between them (young and young 2001)
Soils structure can be defined as the arrangement of soil particles in various aggregates differing in size, shape, stability, and degree of adhesion to one another, and therefore the pore arrangement between them .
Soil structure has a major influence on soil behavior and water and air movement in the soil, and also on biological activities such as root growth and seedling emergence, soil structure plays a vast role in determining soil types, bonding and aggregation as well as the strength or stability of the soil.
A well structured soil has plenty of living spaces, storage spaces, door ways, and passages for utilization by water, gasses, nutrients roots and a vast array of organism. A poorly structured soil is much less endowed and less productive.
Before the creation of the earth, soil existed, it was form the soil that other creation (vegetation, animals ) including human being were created, soil is the home for all living organism, soil provides support for human structure (house and roads) protects archeological treasure (such as gold lead tin sliver zinc etc )and minerals deposits (crude oil and petroleum) as well as provide land filling of human garbage.
It is impossible to talk about other branches of science without talking about soils, imagine the world, if there was no soil, than there will be no living things. The existence of other sciences, such as geology, mining and exploration originated from soil sciences, thus it is accurate to say that soil is the mother of all sciences, and the sole of existence to all living things
Soil, can be defined as the part of the outer mantle of the earth, that is formed from mixture of minerals and decaying organic matter, which extends from the surface , down to the limit of biological forces, soil is formed from the weathering of rocks, (parent materials ) factors that influences soil formation included: climate, living organism, relief or topography parent materials and time.
SUMMARY, RECOMMENDATION AND REFERENCE
Soil structure describes the arrangement of solid parts of soil in ped and the pore spaces between them solid particles constitutes only 50% of the soil while the other 50% are living pore spaces, soil structure is affected by the kind of aggregate that is formed there are 6 categories or types of structures. Some are large some are small others are fine while the rest are coarse, they include, single grain, granular, blocky, platy, columnar and massive
Soil aggregates are the basic unit of soil structure, it formation and stabilization results as the interaction between, soil texture and organic matter which are held together by gravity or electrostatic forces and various chemical glues
Aggregate stability refers to the ability of soil aggregates to resist disintegration when forces of tillage and erosion are applied, poor aggregate and their impact on soils are numerous, bad agricultural practices affects the stability of soils, soils with poor aggregate stability will wither slake or disperse in the presence of water conservation practices should be employed to improve aggregate stabilization.
RECOMMENDATIONS
The effort to keep agricultural soils and land productive and stable to withstand disintegration when managed is a never ending one, agricultural land will be productive and stable to withstand forces, if conversati
on practises are employed in enhancing the development of our soils. It is against this background that the researches wish to make this recommendations.
