Abstract
The study area was chosen in the district of the western Jadwal in Karbala governorate - Iraq, which is located between E44o05'10'' to E44o13'03'' and N32o38'30'' to N32o27'40'', as 100 locations were identified for the depth of 0-30 cm by auger hole sampling method samples were obtained from each site, and kept laboratory measurements. The results of the study showed that the dominant soil texture is medium clay and silt are the predominant separates in the soil. As for the salinity of the soil represented by electrical conductivity, it was low of the dissolution the salts and the land use for cultivation besides the presence of a drainage network a percentage of the organic matter is good. As for assessing the suitability of the land for cultivation, Results showed the use of the standard addition method of land evaluation for the wheat crop by Sys,1993 is better and more accurate than the standard multiplication method for the wheat crop that was also suggested by Sys, 1980, where the very suitable class S1 and the suitable S2 were the predominant cultivars of the addition method, while the non- suitable class N and the least suitable S5 were classes when the methods of multiplication were used.
Highlights
The land assessment is an assessment of its performance, efficiency, or assessment of its potential for various uses and productive uses such as its suitability for agriculture, animal production, forests and other uses related to tourism, wildlife (6)
Van Gool (21) described that the standard common method for producing maps of the Earth's natural resources surveys to assist in making strategic decisions related to management, development and the protection of natural resources is a standard method similar to the assessment of land by FAO (7) as he explained that the main use of maps Earth's digital resource is the spatial analysis of geographic data using the GIS program that can be performed with high accuracy and speed
MATERIALS AND METHODS The study area was chosen in the western Jadwal district in Karbala governorate - Iraq, which lies between E 44o05'0" to E44o13'03" and N32o38'30" to N32o27'40", as 100 locations for depth 0-30 cm hole sampling method and the kriging within the spatial analysis procedures as a nonstationary variance model that was by .Lark (12), the coordinates of the sites and samples the collection shown in Figure (1), as for the area of the study area which is 13001.94 hectares ArcGIS desktop V.10.7 to ensure a complete and accurate mapping of the area
Summary
The land assessment is an assessment of its performance, efficiency, or assessment of its potential for various uses and productive uses such as its suitability for agriculture, animal production, forests and other uses related to tourism, wildlife (6).
