Reclamation of dispersive soil from Yedwingaung village, near Yemyatkyi in, Sagaing Region
Moe Tin Khaing
Salt-affected soils have been attended to recognize not only in myanmar but also in all over the world. The aim of this research is to reclam the solt-affected soil from Yedwingaung village in the vicinity of Yemyatkyi In, Sagaing region by applying soil amendments. To get representative soil samples of this uncultivated area, 20 different sites were selected and collected equal amount of soil from each site. Gypsum as inorganic amendment and vermicompost as organic amendment were utilized and tested in practice by pot experiments. Physicochemical characteristic properties (eg. pH, Electrical Conductivity, Sodium Adsorption Ratio, Exchangeable Sodium Percentage) of these soils were investigated. Fourier Transform Infrared, Energy Dispersive X-Ray Spectroscopy and Scanning Electron Microscopy were also utilized for characterization. According to the values of pH, Exchangeable Sodium Percentage, Sodium Adsorption Ratio and base saturation percent, all soils were represented as dispersive. Then the effeteness of amendments by two strategies were determined by comparing the properties of soils. The improvement of soil microbial activities with the use of treatment were also pointed out by basal soil respiration indicator. Although the dispersive properties had not been completely disappeared after treatments, it was cleared that other qualities of soils were developing. Therefore the applied amendments in this soil reclamation can ameliorate the calcareous dispersive soil by some extant.
