GALVIS, Jesús H; AMEZQUITA, Edgar  e  MADERO, Edgar. Evaluation of harrowing intensity on surface crusting on an oxisol of the eastern plains of Colombia : III. Micromorphological characterization in soil surface.. Acta Agron. [online]. 2008, vol.57, n.1, pp.19-29. ISSN 0120-2812.

To understand changes that happened on soil surface under different pasture and corn systems, it was necessary to observe its microstructure using methodologies such as thin soil sections and sweeping electronic microscopy. Important changes in soil fabric were observed under introduced systems compared to native savanna and forest systems.

Palavras-chave : Orinoquia; soil crusting micromorphology.
