| Phosphorus (P), a dynamic property of soil is one of the absolutely required nutrients for healthy plant growth. Parent materials as well as management practices in a region significantly affect plant available phosphorus (PAP) concentration of soils. The purpose of this study was to determine the PAP concentrations of soils under five different management practices and to analyze and map the spatial distribution of PAP using geostatistical techniques. Soil samples were collected from approximately the corners of 5km* 5km size grid cells within 252.000 ha land in South Eastern Region of Turkey. Total of 110 disturbed samples were taken from 0-20 cm depths, and analyzed for PAP, particle size distribution (sand, silt and clay), soil reactions (pH), electrical conductivity (EC), organic matter (OM) and calcium carbonate content. The P2O5 concentration ranged from 11.6-787.9 kg ha-1 with a mean value of 70.9 kg ha-1. The highest P2O5 concentration was recorded in forest soils (mean 98.9 kg ha-1) and the lowest P2O5 (mean 39.4 kg ha-1) was obtained from soils located in pastures. The highest variation (CV= 155.25%) of P concentration was recorded in wheat-barley fields (rainfed) and the lowest CV (CV 61.53%) was obtained in lentil fields (rainfed). Changes in parent material, climate and management practices in the study area probably contributed to the high variation of P concentration. The semivariogram of PAP best fitted to exponential model. The range of the influence calculated for the PAP was 7020 m. The value for nugget/sill of PAP was 2.77% that indicated a strong spatial autocorrelation. High range value and low nugget/sill ratio … |
