区分土壤肥力的空间变异性对立地特定养分施用具有重要意义。为了了解情况,从印度卡纳塔克邦雅德吉尔区Vandurga村收集了25个土壤样本。分析样品的电导率(EC)、氢(pH)、有机碳(OC)、氮(N)、磷(p< sub>2O5)和钾(K2O)。此外,SPSS(版本。19)利用常规统计分析和ArcGIS技术获取土壤速效养分分布和空间变异性信息。分析结果表明,土壤EC变化范围为0.13 ~ 0.25 dS/m,平均值为0.18 dS/m。PH的变化范围为6.62 ~ 8.82,平均值为7.89。有效OC范围为0.14% ~ 1.90%,平均值为0.78%。N、P2O5和K2O的平均值分别为215.3 kg/ha、31.5 kg/ha和513.4 kg/ha。EC的SD和CV分别为0.031和16.69%,pH、OC、N、p< sub>2O5和K2O的SD和CV分别为0.56和7.04、0.39和51.16、100.9和46.86、19.12和60.61、160.88和31.33。 Spatial variability maps for various nutrients prepared shows the huge variation in the soil nutrients availability. This variability appeared due to lack of balanced application of fertilizers. It was suggested that an appropriate applications of nutrients necessary for selected land based on soil nutrients.
