Arable lands are needed for sustainable agricultural systems to support an ever-growing human population.
Soil quality needs to be defined to assure that new land brought into crop production is sustainable.
To evaluate soil quality, a number of soil attributes will need to be measured, evaluated, and integrated into a soil-quality index using the multivariable indicator kriging (MVIK) procedure.
This study was conducted to determine the spatial variability and correlation of indicator parameters on a field scale with respect to soil quality and suitability for use with MVIK.
The variability of the biological parameters decreased in the order of respiration > enzyme assays and qCO2 > microbial biomass C.
The distribution frequency of all parameters except respiration were normal although the spatial distribution across the landscape was highly variable.
The biological parameters showed little correlation with each other when all data points were considered; however, when grouped in smaller sections, the correlations were more consistent with observed patterns across the field.
To accurately assess soil quality, and arable land use, consideration of spatial and temporal variability, soil conditions, and other controlling factors must be taken into account.
