Resumen:
Several equipments were used in preparing the soil or part of
it. Usualy it is used the same equipament several times or different
equipaments only one time in the same location. Often this is done in an
inadequate manner, leading the producer to spend more time and money and
exposing the soil to erosion losses. The present paper aimed to determine the
desaggregation level in preparing the soil with several horizontal angles of
the disc, proportionated by variations on the transversal bar of a fixed-disc
plow in a non-grated and trated surface before and after plowing a Cambic
Yellow-Red Podzol, Phase Terrace with these data, the user will be able to
decide about the method wich will provide shirift of sesources and time , as
well as soil and water conservation, a good quality of the sowing bed ond
other aspects enherent to soil preparing.
