THE GROUND.

Soil is a very complex system that serves as a support for plants, in addition to serving pantry of water and other elements necessary for the development of vegetables. The soil is known as a living entity in which many live creatures as small animals, insects, microorganisms (fungi and bacteria) that affect life and development of plants in one form or otra.El soil is a open, dynamic, consisting of three phases. The solid phase is made up of inorganic and organic components, leaving a hollow space (pores, chambers, galleries, cracks, crevices and other) that are liquid and gas phases (mainly oxygen and carbon dioxide) . The void volume is mainly occupied by water that can lead ions and substances in solution or suspension, air and roots and living organisms in the soil. All these elements give químicas.Se physical properties and can talk about the evolution of the soil, ie change its characteristics based on climate, presence of animals and plants and human action. Therefore a natural soil, in which the evolution is slow is very different from one grown. Therefore, proper management of soil is needed to preserve their fertility, better results and respect the environment. In addition, a soil analysis is necessary if we manage it properly.

could be collecting soil samples during the trail, then analyze in the laboratory of the Centre.

If soil acidity is plentiful, a pH below 5.6 - the phosphorus is combined with aluminum and iron compounds, making others who are not assimilated by plants.
In contrast the other extreme, an alkaline reaction with pH 8.0 or more, implies that absorption also decreases due to form tricalcium phosphate compounds that are difficult to digest plants. The level of assimilation is at best neutral pH, ie around 7.0 (between 6.5 and 7.5).
