Research ArticleOpen accessIn the keywordsComparison of Selected Chemical Properties of Peat Swamp Soil Before and After Timber HarvestingMuhamad Ismawi Salimin, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Peat swamp is an important component of the world’s wetlands. Once they are disturbed the tendency for the soil degradation is very high. This study compared selected chemical properties of a peat swamp soil before and after timber harvesting. Approach: Peat soil samples were taken at 0-15 cm depth in 6 plots with 0.1 ha each plot at … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 8,792 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThermodynamic Model of Calcium Carbonate System of Soil SolutionAbdulmalik A. Batukaev, Anatoliy P. Endovitsky, Andrey G. Andreev et al.Carbonate system determines the basic processes of soil formation and evolution. The aim of research was to show the importance of chemical Carbonate Calcium Equilibrium (CCE) in soil solutions. CCE causes a degree of soil solution’s saturation with CaCO3 as a factor of carbonate geochemical cycle. CCE depends on chemical composition, pH, Eh, buffering properties of liquid phase, dissolution, migration, … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 18 May 2016 · 7,981 accessesView PDF Cite
