Nutrient stoichiometry and labile carbon content of organic amendments control microbial biomass and carbon-use efficiency in a poorly structured sodic-subsoil
Application of organic amendments (OAs) combined with inorganic fertilizers or gypsum in
poorly structured soils has recently received much attention as an agricultural management …

Ameliorating alkaline dispersive subsoils with organic amendments: Are productivity responses due to nutrition or improved soil structure?
Background and aims Alkaline dispersive subsoils are characterised by multiple
physicochemical constraints that limit plant water and nutrient acquisition. Subsoil …

Additive effects of organic and inorganic amendments can significantly improve structural stability of a sodic dispersive subsoil
Sodic dispersive subsoils pose significant constraints to agricultural productivity and
sustainability in arid and semiarid regions. Gypsum and organic amendments (OAs) have …
