Identification of regional soil quality factors and indicators: a case study on an alluvial plain (central Turkey)

摘要: Abstract. Sustainable agriculture largely depends on soil quality. The evaluation of agricultural quality is essential for economic success and environmental stability in rapidly developing regions. In this context, a wide variety methods using vastly different indicators are currently used to evaluate This study was conducted one the most important irrigated areas Konya central Anatolia, Turkey, analyze Cumra County combination with an indicator selection method, minimum data set total 38 soil parameters. We therefore determined principle component analysis assess area evaluated basis scoring function. From broad range properties analyzed, following parameters were chosen: field capacity, bulk density, aggregate stability, permanent wilting point (from physical properties); electrical conductivity, Mn, nitrogen, available phosphorus, pH, NO3-N chemical urease enzyme activity, root health value, organic carbon, respiration, potentially mineralized nitrogen biological properties). According results, chosen found as sensitive they can be evaluating monitoring at regional scale.
