- Abstract
Spatial properties of field soils vary in a complex manner. Especially in arid and semiarid areas, this variability affects plant quality and crop production. An experimental field plot was extensively sampled regarding soil water (378 gravimetrical samples), soil chemical content (314 samples), and crop yield and chemical content (26 samples) at the Cherfech agricultural field research station in Tunisia. Geostatistical analyses were made to gain a better understanding of the in situ variability of soil water, soil chemical and crop properties. Ranges of correlation were found to vary over distances between 5 and over 40 m. Nugget and sill values for semivariograms were almost an order of magnitude larger for crop samples compared to...

Geostatistical analyses were made to gain a better understanding of the in situ variability of soil water, soil chemical and crop properties. Ranges of correlation were found to vary over distances between 5 and over 40 m. Nugget and sill values for semivariograms were almost an order of magnitude larger for crop samples compared to soil samples. The crop yield components appeared to have larger variability as compared to crop chemical components.
