Systematic use of Saline Water with Leaching Fraction for Improving Soil Health under Arid Conditions

evaluation of management strategies for improving water use efficiency of wheat under saline conditions

on-farm management practices with the aim of improving water use efficiency (wue) are among the practical ways of overcoming the water scarcity problem. this study aims to investigate ways of implementing agricultural water management in abarkouh region, yazd province, which mainly deals with problems such as water scarcity and salinity of soil and water resources. to this end, the resulting sc...

Evaluation of the SALTMED model for sorghum under saline conditions in an arid region

SALTMED model has been developed to predict yield, soil salinity and watercontent under saline conditions. A two year field experiment was carried out during2012-13 to calibrate and validate the model for sorghum. Plants were irrigated withsalinity levels of 2, 6, 10 and 14 dS m-1. Results showed that there were significantdifferences between the observed and simulated sorghum dry matter (SDM) ...

Improving soil surface properties: a driving force for conservation tillage under semi-arid conditions

The effect of long term conservation tillage (CT) application on soil organic carbon (SOC) concentration, and on stratification ratios (SR) of SOC, soluble organic carbon (SOCs), microbial biomass carbon (MBC) and protease activity (PA) has been studied. The SR was established dividing values of these variables at 0-5 cm depth by values at 10-25 cm depth. The results were compared with those ob...
