Conteúdo: | The effect of different rnethods of soil preparation on soil moisture loss, weed growth and soil resistance to penetration has been quantified for the Latosols of Bebedouro experiment station of CPATSA/EMBRAPA, Petrolina, PE, Brazil. The methods studied are manual preparation, preparatiort by animal drawn wheeled tool carrier and tractorized implements. The drying characteristics of three fields with different soil physical properties were studied prior to conducting the experiment. The different methodg of soil preparation caused the soil moisture loss differently. The plot prepared by animal drawn tool carrier retained more moisture for Jonger time evert at deeper layers. The soil resistance to penetration ort the surface increased with time with little variation at deeper layers.
