ZUCOLOTO, Moises et al. PHYSICAL ATTRIBUTES OF A RED-YELLOW LATOSOL UNDER DIFFERENT VEGETABLE COVERINGS. Rev.Fac.Nal.Agr.Medellín [online]. 2008, vol.61, n.2, pp. 4600-4604. ISSN 0304-2847.
The objective of this study was to evaluate the modifications of the physical attributes of a Red-Yellow Latossol (Oxisol) in three different vegetable coverings and two depths. The experiment was carried out in the Experimental Farm of Escola Agrotécnica Federal de Alegre (EAFA), Alegre City - ES, Brazil . The treatments were constituted by three vegetable coverings, soil discovered, Mangifera indica L. and Coffea canephora Pierre with two differents depths (0-0.20 and 0.20- 0.40 m). For each vegetable covering, five samples had been collected deformed distributed at random in the area. The extreme use to the long one of the 10 years in the soil discovered before busy with horticulture, made with that it presented values of fine bigger sand and clay in relation to the other soils coverings. The depth of 0 - 0.20 m presented greaters thick sand texts, fine sand in relation to the depth of 0.20 -0.40 m. The clay presented higher concentration in the depth of 0.20- 0.40 m and the dispersed clay in water presented concentration difference in evaluated environments.
