Soil is very important for the plants. It is not merely a support system, but a complex world from which the roots obtain water and other required elements. In addition, soil is inhabited by small animals, insects, microorganisms (e.g. fungi and bacteria) which all influence the plant life in one way or another. One can talk about a soil evolution, that is, change in its characteristics based upon climate, presence of animals and plants as well as man’s action. Therefore, a natural soil, in which evolution is slow, is very different from a cultivated one. Soil is composed of solids (minerals and organic matters), liquids (water and dissolved substances), gases (mostly oxygen and carbon dioxide) and contains living organisms. All these elements provide its physical and chemical properties. Managing the soil properly is necessary in order to preserve its fertility, obtain better yield and respect the environment. Testing the soil on the other hand is a must in order to manage it properly

The soil analysis is very useful, in order to plan fertilization and to know the residues of fertilizers in relation to the crop, tillage and climate. An analysis can highlight shortages and help the understanding of the causes of an abnormal growth. Testing the soil during the crop cycle and comparing the results with the plant growth can be an useful experiment for the next cultivation.

An analysis can highlight shortages and help the understanding of the causes of an abnormal growth. Testing the soil during the crop cycle and comparing the results with the plant growth can be an useful experiment for the next cultivation. The nutrient content , pH ,NPK etc., of the soil has to be tested for soil fertility.Depending on the fertility of the soil we can decide on what crop can be cultivated in that soil. We do help farmers in checking the soil fertility
