Soil salinization and sodification are common processes that particularly characterize drylands. These can be attributed either to natural conditions or anthropogenic activities. While causes include factors such as climate, lithology, topography, pedology, human mostly related agricultural land-use, specifically, irrigated agriculture. The objective of this study was thoroughly review topic, w...
Excessive salt rate can adversely influence the physical, chemical, and biological properties of soils, mainly in arid and semi-arid world regions. Therefore, salt-affected soils must be reclaimed to maintain satisfactory fertility levels for increasing food production. Different approaches have been suggested to solve these issues. This short review focuses on selected studies that have identi...
Regaining the agricultural potential of sodic soils in the Indo-Gangetic plains necessitates the development of suitable salt tolerant rice varieties to provide an entry for other affordable agronomic and soil manipulation measures. Thus selection of high yielding rice varieties across a range of sodic soils is central. Evaluation of breeding lines through on-station and on-farm farmers' partic...
Soil salinity is a key abiotic stressor that negatively impacts plant growth and restricts land use by causing degradation (Gamalero, et al. [1]). Saline sodic soils are characterized their high soluble salt content pH, respectively, which result in imbalances nutrient cycling reduced organic content, carbon stocks, microbial activity the soil [3].
An area of saline sodic soil was intensively drained and treatments of gypsum (31 t/ha) or sulphur (6 t/ha) were applied, while control plots received no ameliorants. Physical and chemical soil analyses showed gypsum to have an ameliorative effect slightly superior to that of sulphur. Both treatments were more beneficial than the control but differences were not always as great as expected. For...
