Evaluation of the land degradation severity by using the ordinary kriging in west Nubariya region, Egypt [electronic resource].

Includes references.

Sugar beet area (80,000 fed.) represents one of the newly reclaimed areas in West Nubariya since 1989. The agriculture development in the area is facing human-induced degradation of water logging and salinity problems mainly due to unsustainable agricultural practices. The present study aims to apply ordinary kriging technique to estimate the spatial variability of land degradation severity at sugar beet area during years from 1997 to 2003. The study involves: (1) Creating Digital Terrain Model (DTM) to obtain physiographic mapping units, (2) Defining the differentiating land qualities and creating soil thematic value maps, (3) Determining the degradation status of each soil mapping units and defing the extent of land degradation severity between years 1997 and 2003.
