Variabilidade espacial de atributos físicos em latossolo amarelo de área experimental

Abstract

Knowledge of the variability of soil properties constitutes an important tool that we can employ a more appropriate management. The objective of this study was to investigate the spatial variability of soil physical properties in the area of production under experimental Oxisol. The study was conducted at the Experimental Farm Cha-of- Garden, CCA / UFPB, in 2011. The trial was conducted in Oxisol and analyzed the following attributes: soil density (Ds), moisture content and penetration resistance (RMP). We performed geostatistical analysis and descriptive. Soil bulk density and moisture were the variables with greater and lesser extent, 213 and 6.5 m, respectively, expressing their knitting sample for future studies. The penetration resistance showed no spatial dependence in any of the layers analyzed, characterizing nugget effect and variability in the experimental area.
