GALVIS, Jesús H; AMEZQUITA, Edgar e MADERO M, Edgar. Evaluation of harrowing intensity on surface crusting on an oxisol of the eastern plains of Colombia . II. Physical characterization in soil surface. Acta Agron. [online]. 2007, vol.56, n.4, pp. 191-194. ISSN 0120-2812.
The outlined methodology in this article allowed correlating soil sealing and soil physical properties as structural stability, infiltration velocity, soil loss erosion, run-off, normal and torsion resistance and aggregate distribution. The output showed that improved pastures after eight years of sowing produced a relatively positive response to soil erosion and mechanical strengths. But periodic farming and fertilization that are required for corn production although resulted in good seed bed preparation and created a good environment to store moisture, it allowed an increase of soil erosion and decrease of soil structure stability.
