Physical characterization of the soil under different forms of preparation in an organic production system

Abstract

Soil preparation and management systems determine the physical conditions for plant growth
and crop productivity. The objective of this work was to evaluate the physical properties in two
soils in organic cultivation with different types of soil preparation. The soil preparation is: micro
tractor (Mt) of 12 hp with use of rotary tractor and (T) 75 hp force with the use of grille and subsoiler.
The differences between the two soils and between the depth ranges were evaluated. A
significant difference was found between the averages for the soil density, porosity, penetration
resistance and soil moisture attributes. Soil preparation with the use of implements such as
grids, subsoiler and rotary improves the physical conditions of soils for cultivation if used consciously
and suitable conditions.
