background:   purpose:   method:   results:   conclusion:

field saturated hydraulic conductivity (kfs) is one of the most important soil properties that considerably contribute to soil quality. however, specifically in the structured soils, the measurement of kfs is difficult and time-consuming. therefore, verifying the simple and fast methods for kfs measurement is needed for effective soil monitoring. this study was conducted to investigate the effe...

boron toxicity is becoming more extensively widespread in arid and semi arid regions, due to the application of either saline waters or irrigation waters containing a relatively high b content. results of research indicate that addition of certain plant nutrients such as n may reduce the harmful effect of high b levels. therefore, the present experiment was undertaken to evaluate the interactiv...
