Abstract
In Egypt require to improve agricultural production to save food demand with increase population. Soil salinity is a significant attractive problem for agriculture in irrigated areas. As a result, monitoring of soil salinity is required for salinization control. One of the greatest challenges faced by Egypt’s decision-makers is the acquisition of reliable integrated soil salinity information to introduce and recommendation of a simple approach to formulating a guideline for stakeholders. Saline affected areas are vast, making it extremely difficult to examine soil quality with field and laboratory data to provide reliable approach to forecast and monitor soil salinity. Objective of this paper is to research remote sensing and ArcGIS tools by Geo-Statistical Analyst techniques to map saline-sodic heavy clay soils of the Tina plain area in Egypt. Tina Plain characterizes a serious area for potential development of agricultural land in Egypt. Satellite images were downloaded by Landsat 8, Sentinel-2A, Sentinel-1, and Synthetic Aperture Radar C-band data were wont to map soil salinity within the area. By coefficient of correlation method were preformed, evaluated and compared of the Three models. The results revealed that the Sentinel-2A optical imaging satellite yielded the very best prediction performance. ArcGIS Geo-Statistical Analyst was also successfully wont to predict and map the saline-sodic heavy clay soils with a mistake percentage of about 4.28%, which is taken into account as a minor error. generally, the study confirms that the Remote Sensing and ArcGIS Geo-Statistical Analyst are often considered by researchers and decision-makers as a credible, cost-effective, and time-controlled techniques to work out and predict the extension of soil salinity.
Highlights
One of the reasons for problems is Soil salinity especially in the arid and semi-arid zones due to its negative outcomes on agricultural productivity and sustainable development
For every sample location the cell digital number (DN) values for every band of the pictures were extracted to the attribute table of sample locations. all data from the attribute table convert to an excel file
The mean for every one of the reflected vitality groups was utilized as autonomous factors inside the relapse models
Summary
One of the reasons for problems is Soil salinity especially in the arid and semi-arid zones due to its negative outcomes on agricultural productivity and sustainable development. Saline soil conditions have a reduction resulted in the value and productivity of considerable areas of land throughout the world (1) Salinity problem managing to attenuate. Many cultivated areas suffering from an increased groundwater table and salinity of soil in the Middle East. The explanations for this need irrigation practices, increase evaporation rates, and a rise in groundwater salinity (4). In Egypt, about a million ha (33%) of the entire irrigated cultivable lands along the Nile are salt-affected (5)
