Influence of Landform on the Spatial Variability of Soil Fertility in Central State Farm, Jetsar, Sri Gangananar, District of Rajasthan

Abstract

Understanding the spatial variability in soil parameters is important for efficient management of soil resources. The present study evaluated the influence of landform on the spatial variability of chemical and physical attributes of soils of Central State Farm, Jetsar, Sri Ganganagar district Rajasthan. The highest available macro and micro-nutrients content were observed in soils of aeo-fluvial plain followed by stabilized sand dune and active sand dune. The soil samples across the landforms were low in organic carbon content barring 3 percent soil samples of aeo-fluvial plain. The mean available N was 153, 139 and 112kg ha-1 in aeo-fluvial plain, stabilized sand dune and active sand dune, respectively. The available P in stabilized sand dune and aeo-fluvial plain was found in high category, whereas medium in active sand dune area. About 41, 22 and17 percent soil samples of aeo-fluvial plain, stabilized and active sand dunes were classified in high category, for K respectively.
