     We analyzed the physical and chemical properties of different
     soils, as full  characterization of soil and special analysis of
     micro-elements. These analyses  were conducted in the laboratory
     analysis of soils, plants, water and fertilizers  in the La Molina
     National Agrarian University (UNALM). To which the different soil 
     samples were dried to the environment, screened (mesh 0.5xo, 5 mm)
     and sterilized by  steam 4 to 5 hours with a Lindinger Steam
     aerator SA150 and SA700, with the possible  aim of eliminating
     bacteria saprophytic or antagonists to prevent the growth of
     bacteria  (R.solanacearum).
