[AGE31-P08] Effects of amendments on improvement of aggregate stability and soil pH in salt affected and acid sulfate soils in the South of Viet Nam
Keywords:Calcite, Organic amendments, soil structure, soil incubation, soil reclamation, soil degradation
Application of calcite and a combination of calcite and compost raised soil pH of all the soils. By applying compost, a remarkable increase in pH was observed in SS and AS, but an insignificant increase was observed in AASS. Both compost and the combination of calcite and compost improved aggregate stability, while calcite addition enhanced aggregate dispersion. Thus, combination of calcite and compost is recommended for soil reclamation of not only pH rise but also enhancing aggregate stability.
