Applying Spatial Geostatistical Analysis Models for Evaluating Variability of Soil Properties in Eastern Shiraz, Iran
ABSTRACT- The information on the spatial properties of soil is vital to improve soil management and to increase the crop productivity. Geostatistical analysis technique is one of the most important methods for determining the spatial properties of soil. The aim of this study was to investigate spatial variability of soil chemical and physical attributes for field management in eastern Shiraz, I...
متن کاملMapping Spatial Variability of Soil Salinity Using Remote Sensing Data and Geostatistical Analysis: A Case of Shadegan, Khuzestan
Extended abstract 1- Introduction Soil salinity is one of the most important desertification parameters in many parts of the world. Thus, preparing soil salinity maps in macro scales is necessary. Water and soil salinity as one of the contributing parameters in desertification, cause soil and vegetation degradation. Soil salinization represents many negative effects on the earth systems such ...
متن کاملMapping spatial variability of soil salinity in a coastal area located in an arid environment using geostatistical and correlation methods based on the satellite data
Saline lakes can increase the soil and water salinity of the coastal areas. The main aim of this study is to distinguish the characteristics of the spectral reflectance of saline soil, analyze the statistical relationship between soil EC and characteristics of the spectral reflectance of saline soil, and to map soil salinity east of the Maharloo Lake. The correlation between field measurements ...
متن کاملCatchment-scale spatial variability analysis of soil hydro-physical properties in a semi-arid region of Iran
Soil hydrau-physical data are important for many hydrological modelings. They are the main variables controllingthe key processes such as water and chemicals movement and transport in the soil profiles. This study was conductedin order to analyze the spatial distribution of selected soil hydrau-physcial characteristics including infiltration rate(IR), saturated hydraulic conductivity (Ks), bulk...
متن کاملAnalysis of spatial variability of soil properties using geostatistics and remote sensing

For this purpose, a region with an area of 600 hectares in Qom that considered Salt Lake watershed. Specified methods used include inverse distance methods, radial functions, and prediction local general estimate. Krig...
متن کاملSeasonal variability in water chemistry and sediment characteristics of intertidal zone at Karnafully estuary, Bangladesh
The Karnafully is one of the most important rivers due to its profound influence on water chemistry and sediment characteristics. The present study intended to assess the quality of water and sediment from intertidal zone of this river in respect to the pollution index. Seasonal water and sediment samples were collected during four seasons (Monsoon, post-monsoon, winter, and pre-monsoon) of 201...
