	abstract = {<p>One of the most cost-effective approaches in precision farming is the managing of relatively contiguous homogeneous zones in the field. Soil samples were collected in a 3 ha field of the CRA-Cereal Research Centre{\textquoteright}s experimental farm located in Foggia (southern Italy). Soil carbon mineralization indices and physical-chemical properties were interpolated by using the geostatistical techniques of kriging and co-kriging. The application of a clustering algorithm, based on a non-parametric density estimate, to the (co)kriged surface variables produced the subdivision of the field into four distinct classes. This information can be useful for the site-specific supply of nutrient inputs, in order to match crop requirements with intrinsic patterns of soil fertility.</p>
