Afforestation, settled before 60–90 years and adjacent solonetzic grasslands, representing the natural vegetation cover were compared in this study based on their basic soil characteristics (pH, CaCO3 content, organic carbon (SOC), exchangeable sodium percentage (ESP)) up to 2 m depth. The assumption was that plantings of arbour can change sodic soils not only superficial layers but even larger...

Sodicity affects a larger area than salinity, but research on the sodicity tolerance mechanism is limited. The study was carried out to screen 120 finger millet genotypes under sodic soil conditions and identify sodicity-tolerant genotypes. experimental field were sandy clay loam with pH 8.9, electrical conductivity (EC) 0.94 dSm-1 exchangeable sodium percentage (ESP) 21.5, which naturally sodi...

The main limiting factors in saline-sodic soils are high amounts of salts, low soil organic matter (SOM) and lowavailability of macro and micro-nutrients. The effect of different amounts of nano iron oxide powder and urban solidwaste compost coated sulfur (USWCS) on the chemical properties of a saline-sodic soil was investigated. The experimentwas conducted using a randomized complete block des...

Many avocado growers are debating the question of whether or not to apply calcium to their groves. Some advocates say calcium is a necessary soil additive, creating almost magical improvements in soil chemical balance and tree growth. Others maintain that, since calcium is common in California soils, it serves only to improve soil structure in sodic soils or soils with permeability problems due...

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].

" A, a saturated solution of sulphanilic acid in dilute (1 in 20) hydrochloric acid; B, a ?5 per cent, solution of sodic nitrite in distilled water. (Both of these solutions must be fresh?especially the latter, which cannot be depended on for more than a week at the longest. When they are mixed, of course, a solution of sulphanilic acid containing free nitrous acid is produced, which is the act...

High contents of soluble salts accumulated in a soil can significantly decrease the value and productivity of agricultural lands. Present recommendations for reclamation are usually based only on relatively simple and often empirical relations. In this paper we give a brief overview of many unique physical and chemical factors important to reclamation contained in the one-dimensional multicompo...
