Abstract The use of nano-gypsum in low doses can be an innovative method to mitigate salinity-sodicity effects and enhance spinach growth saline-sodic soil. We evaluated four 960, 480, 240, 120 kg ha ?1 , addition the control recommended conventional gypsum dose (~ 30 t ), a randomized complete pot experiment. pots soil were incubated laboratory for 2 months leached 5 times another months. Then...

prosopis cineraria (l.) druce (kahour in persian) is a native and indicative species of saharo-sindian region. prosopis forest in iran extends from the beach of persian gulf and oman sea in boushehr, hormozgan and sistan-baluchistan provinces to south of kerman province. in this research ecological conditions of prosopis such as floristic diversity, climate, soil and the biomass were studied. i...

Enchytraeus albidus is a freeze-tolerant enchytraeid found in diverse habitats, ranging from supralittoral to terrestrial and spanning temperate to arctic regions. Its freeze tolerance is well known but the effect of salinity in this strategy is still poorly understood. We therefore studied the combined effect of salinity (0, 15, 35, 50‰ NaCl) and sub-zero temperatures (-5, -14, -20°C) on the f...

Abstract. Declining soil-saturated hydraulic conductivity (Ks) as a result of saline and sodic irrigation water is major cause soil degradation. While it understood that the mechanisms lead to degradation can irreversible changes in Ks, existing models do not account for hysteresis between rehabilitation processes. We develop first model effect on Ks explicitly includes hysteresis. As such, ide...
