The quality of soil maps depends on their ability to exhibit the soil variability. This study aims to investigate the soil spatial variability in S2 unit of a semi-detailed qualitative suitability map (1:50000 scale) for irrigated barley. Forty nine soil samples were collected in land unit 2.1 at 0-20 cm depth using regular network sampling method to determine the content of salinity (EC) , alkalinity (ESP), CaCO3, pH, Organic Carbon (OC), CaSO4, Sand, Silt and Clay parameters. The greatest variability observed in the OC (Coefficient of variation = 300) and Caso4 (Coefficient of variation=0.40) respectively. The obtained result showed that the incorporating of FAO method and GIS techniques in land suitability evaluation for barley gave lower estimate of land index and yield than FAO methods alone (Storie and Square Root methods). The better accordance between estimated yield potential and observed yield potential by Square Root- Kriging method revealed that it was more accurate than the conventional FAO methods alone.Keywords

The objective of this study is to assess a GIS-based model for barley production potential in Damghan plain of Iran. The assessment of Land Production Potential for barley, Using Geographic Information System method was used on the crop requirements, climatic and soil properties which will allow the prediction of crop yield. Integrating a crop growth model with GIS allowed studying the variability of barley production potential in different conditions at a regional scale. Regarding to FAO model, the estimated LPP values for the studied area varied between 353 to 5278 kg.ha-1 respectively. This study shows that the average farmers' yield was higher than the calculated LPP values by GIS method. The computed values of net biomass production and yield showed that the barley production potential was almost suitable in Damghan plain. One notable limitation for this method is that it requires an accurate assessment of effective parameters on crop yield.Keywords
