Soil is a biological ecosystem, through which the vital activity of living organisms is possible.The most important characteristic is its fertility.Every farmer knows that it is the composition and characteristics of the soil depends on the quality and properties of the future harvest.
Soil fertility
on cultivated, well-groomed land crops grow up healthy and strong and give rich crops of high quality.Soil fertility - is its ability to provide the necessary plant nutrients, water and air.Cultivated land, situated in farming techniques at a high level, are suitable for growing various plants.
Soil fertility depends on many factors
natural structure of the soil, climatic conditions, availability and the level of groundwater, soil contamination - a natural factors forming soil fertility.
Dirt is the most fertile soil layer that is formed over hundreds of years.To destroy life-supporting layer of soil can be just a few years.If you violate the conditions of normal farming black soil undergoes leaching of humus, soil disturbance, destruction of many microorganisms, the deterioration of the inflow of water and air.The soil loses its ability to deliver the right amount of nutrients to the plant roots, the plant world weakened immune system - and productivity decreases.
How to improve soil fertility
There are areas with dense structure, clayey, poor in these little plants required nutrients.To restore soil fertility, agricultural practices used by many: loosening using peat, lime, sawdust, wood ash.Maintain correct farming helps the science of soils, their formation, composition, structure and properties.It is important to understand that soil formation has its own laws of geographical distribution.There is a definite relationship with the environment of the soil, which determines the formation and development of fertility.Scientists are studying the way of a rational approach to the use of soil in agriculture to changes in soil conditions agrokulturnogo.
inseparable concepts "soil and fertility"
result of the natural flow of the formation of the soil and the soil, the impact of human cultivation of soil fertility is blocked.The development of productive forces, the improvement of economic and social conditions have a positive effect on soil formation.
special role in soil formation phenomena are living organisms, first of all, green plants and microorganisms.In turn, thanks to the special soil properties is of great importance in the life of the organic world.It - a product and an element of the landscape, a special natural body, an important natural environment around the globe.The task of humanity - to preserve and improve the quality of the fertile soils on Earth.
