Abstract

The aim of this study is to evaluate land uses, using physical and chemical
attributes in the irrigated perimeter Ico-Mandantes, between Petrolândia
and Floresta, in the semiarid region of Pernambuco, Brazil. The identified
uses of the land are as follows: short cycle crops (C), fruit (F), pasture (P),
abandoned areas (D), and native vegetation (V). This study evaluated the
uses C, F, D, P and V. In both places, samples were collected from deformed
soil at 0–10, 10–30, and 30–60 cm, as well as non-deformed soil from the
first two layers to the physical determinations and chemical properties. The
data of physical and chemical analyses were subjected to descriptive linear
analysis and multivariate analysis, the technique of principal component
analysis, and clustering by the Tocher method. The use of the native
vegetation differed from all other uses among the analyzed layers, thereby
indicating that the productive uses which were evaluated, promote in fact
changes in the physical and chemical layers studied. The analysis of the
physical and chemical attributes do not differentiate any of the productive
uses systematically analyzed in all layers.
