In arid irrigated regions, the proportion of crop production under deficit irrigation with poorer quality water is increasing as demand for fresh water soars and efforts to prevent saline water table development occur. Remote sensing technology to quantify salinity and water stress effects on forage yield can be an important tool to address yield loss potential when deficit irrigating with poor...

Saline soils and saline irrigation waters present poten­tial hazards to canola production. Therefore, in this study in order to find indicators for salt tolerance, the changes of proline content and the activities of antioxidant enzymes were investigated in two canola genotypes (H308, H420) under various salt concentrations (0, 50, 100, 150 and 200 mM). Results showed that compared to the contr...

Saline to freshwater invasions have become increasingly common in recent years. A key hypothesis is that rates of freshwater invasions have been amplified in recent years by increased food concentration, yet this hypothesis has remained unexplored. We examined whether elevated food concentration could enhance freshwater tolerance, and whether this effect evolves following saline to freshwater i...

Industrial activities on the coast of Kali Mireng affect level water pollution. Pollution potential indicators describe quality. This study aims to determine quality coastal waters. The research was carried out in April-May 2021. We used chemical and physical parameters such as turbidity, pH salinity. temperature five stations with a minimum average value 270 C an maximum 30.70 C. salinity drin...

Wetland degradation in the Upper South East of South Australia is an urgent management concern. Scant recent environmental data is available for the region and long term monitoring data is lacking. Usually a palaeoecological analysis is able to reveal environmental change in the medium to long term past. However, the region is not conducive to palaeoecological investigation due to a fluctuating...

Alterations of plant growth, nitrogenase activity and nutrient concentration as a consequence of salt treatments were studied in five chickpea Cicer arietinumL.) cultivars from Spain and Syria. Plants, in symbiosis withMesorhizobium ciceri ch-191 strain, were grown under controlled onditions for 32 days and subjected to salinity stress. Parameters of growth and nitrogen fixation were affected u...

desertification relates to the both the process and end state of drylands degradation. salinization and alkalinization are two indicators of soil degradation in arid and semi-arid regions. the main objectives of this research is monitoring of soil salinity using high spectral and spatial resolution of remote sensing to assess desertification in the marvast plain, yazd province. two images of te...

The objective of this study was to identify the effect of different land uses in peri-urban agriculture on the soil properties. Soil health indicators were evaluated in the top 10 cm at five tilled agricultural sites involving different cropping systems and use of agrochemicals within the peri-urban agricultural areas of Yaounde, Cameroon, and compared with a native forest land. The experimenta...
