The Technologies setting at Agricultural production system have the main characteristics vertical productivity, reduced costs, soil physical, chemical and biological improvement to promote sustainable growth. Thus, study aimed determine variability linear special correlations between plant attributes in order select indicate good representation of physical quality for forage productivity. In growing season 2006, on Fazenda Bonança Pereira Barreto (SP), productivity autumn corn (FDM) an irrigated no-tillage properties were analyzed. purpose was spatial properties, indicator related yield. A geostatistical grid installed collect data, with 125 sampling points area 2,500 m². results show that studied did not vary randomly data low very high, well-defined patterns, ranging from 7.8 38.0 m. On other hand, correlation highly significant. pairs dry matter versus microporosity stem diameter bulk density best correlated 0-0.10 m layer, while - macro total porosity inversely same layer. However, point view, there a high inverse microporosity, so layer can be considered quality, view
