Traditional mapping of salt affected soils (SAS) is very costly and cannot precisely depict the space–time dynamics soil salts over landscapes. Therefore, we tested capacity Landsat 8 Operational Land Imager (OLI) data to retrieve salinity sodicity during wet dry seasons in an arid landscape. Seventy geo-referenced samples (0–30 cm) were collected March (wet period) September be analyzed for pH...

The rapid increase in soil salinization has impacted agricultural output and poses a threat to food security. There is an urgent need focus on improving fertility yield, both of which are severely influenced by abiotic variables such as salinity sodicity. Abiotic forces have rendered one-third the overall land unproductive. Microbes primary answer majority production’s above- below-ground probl...

This paper focuses on the adverse effects of soil sodicity and alkalinity growth barley (Hordeum vulgare L.) in a rainfed environment south-western Australia. These conditions cause accumulation salt (called ‘transient salinity’) root zone, which decreases solute potential solution, particularly at end growing season as dries. We hypothesized that two approaches could help overcome this stress:...

Soil salinity and sodicity are significant issues worldwide. In particular, they represent the most dominant types of degraded lands, especially in arid semi-arid regions with minimal rainfall. Furthermore, these areas, human activities mainly contribute to increasing degree soil salinity, dry areas. This study developed a model for mapping using remote sensing geographic information systems (G...

The dewatering of flocculated high density slurry presents a significant challenge to most mining industries. new technologies treat require consistent and robust flocculation method in order enter the market tailings management. slurry, however, due its complexity, is always be undertaken appropriately evaluate performance correctly. This paper probes complexity by using torque-controlled mixi...

Phytoremediation is an efficient technique for the reclamation of salt-affected soils by growing plants. The present study aims to evaluate intercropping halophyte Atriplex nummularia Lindl. with naturally occurring species (Mimosa caesalpiniifolia Benth, Leucaena leucocephala (Lam.) de Wit and Azadirachta indica A. Juss.) adapted semiarid regions as a management capable enhancing phytoremediat...

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...
