Land degradation due to soil salinity and sodicity is a serious concern in arid ecosystems.
Despite the importance of conservation tillage in carbon sequestration and improving soil …

Soil sodicity is a major ecological problem in the western Songnen Plain of Northeast China
and rice cultivation is the main approach used to mitigate saline-sodic soils. However, rice …

Remediating saline–sodic soils with organic amendments is increasingly seen as a cheaper
and sustainable alternative to inorganic materials. The reclamation potential of biochar …

crop** is steadily declining due to various soil degradation processes, a major one of …

Reclamation of salt-affected soil has been identified by the FAO as being critical to meet the
needs to increase agricultural productivity. This paper reviews commonly used reclamation …

The mechanisms that assist in the reclamation of salt-affected soils in arid and semi-arid
regions when treated with organic amendments have not been well characterized. In this …

Soil salinity and sodicity are escalating problems worldwide, especially in arid and semi-arid
regions. A laboratory experiment was conducted in soil columns to investigate redistribution …

Soil salinity and sodicity are among the main problems for optimum crop production in areas
