STUDY ON PROTECTION(REPAIR) METHOD OF SALT DAMAGE BY CAPILLARY BARRIER USING CRUSHED SHELL PARTICLES (FISHERY BYPRODUCTS)

Abstract

 Agricultural productivity decreases due to the salt damage of that the salty ground water level gradually rises resulting in appearance of salt crystals on the ground surface associated with annual repeat of rainy and dry seasons. In this study, a experiment was conducted in order to investigatigate a practical applicability of the capillary barrier(CB) using crushed shell particles instead of gravel in the lower layer to the salt damage and the authors make clearly utilizing such materials to protect the salt damage.
