The main objective of this study was to analyze, with geostatistical techniques, the soil variability for some soil parameters on a 12-ha field cropped with durum wheat in Foggia (Southern Italy). Soil samples were collected at 100 georeferenced locations in 2005 and 2007. The application of multivariate geostatistical technique, called factorial co-kriging, allowed the delineation of the field into 3 main clusters. Contingency tables, k statistics and Q-Q plots were applied to assess the temporal variation. The results showed a significant increase in soil organic matter and a decrease in P content up to 40 cm depth during the trial period.

Abstract
The main objective of this study was to analyze, with geostatistical techniques, the soil variability for some soil parameters on a 12-ha field cropped with durum wheat in Foggia (Southern Italy). Soil samples were collected at 100 georeferenced locations in 2005 and 2007. The application of multivariate geostatistical technique, called factorial co-kriging, allowed the delineation of the field into 3 main clusters. Contingency tables, k statistics and Q-Q plots were applied to assess the temporal variation. The results showed a significant increase in soil organic matter and a decrease in P content up to 40 cm depth during the trial period.| File | Dimensione del file | Formato | |
