MESTAS, R. M. et al. Spatial variability of soil physical and hydrological characteristics in relation to the productivity of bean (Phaseolus vulgaris L) irrigated under no-tillage system. Rev. de Ciências Agrárias [online]. 2010, vol.33, n.1, pp.307-313. ISSN 0871-018X.
The spatial variability of a soil used for bean production under an irrigated no-tillage system was studied. This study aimed to evaluate the spatial dependence of soil physical and hydrological characteristics in relation to the spatial variability of the irrigated bean yield. For that reason, 60 sampling points were planted and demarcated in a 3 x 3 m grid. Disturbed samples were collected for determining soil density. In the field, soil resistance to penetration and saturated hydraulic conductivity were determined. The spatial dependence was analyzed by geostatistics using punctual kriging. According to the results, it is possible to observe that the obtained regressions among maps were significant; soil density and resistance to penetration were negatively related to the yield, while the saturated hydraulic conductivity was related positively.
