    Abstract

    The behavior of Na-salt in the depth of salin soil determine water and nutrient plants uptake. The high solubility of salt in the soil can be copied through the replacement of Na by another cation then continued with the washing. Research conducted to evaluate the changes in exchangable- Naon depth of 0-20 cm through the rise of fields and the ammendment application. Results of research indicate that the soil column capable of exch-Na reduce the depth of 0-20 cm until 60 days after incubation (DAI), each of 3263, 2776, and 2239 me/100g on the soil column thickness of 80, 100, and 120 cm. The provision of dolomite, gypsum, and mangrove leaves suppressed the exch-Na each of 2753, 2829, 2733 me/100g. Decreasing ofexch-Na not offset on pH, but the soil EC down a little and vary depending on the type of soil ammendment and the high ground in the fields. The changes of the soil column thickness makes the soil EC 1938, 2025, and 2308 mS/cm respectively for 80, 100, and 120 cm. Giving dolomite, Gypsum and mangrove makes soil EC each of 2128, 2194, and 2139 mS/cm. Keywords :The behavior of Na-salt, soil column thickness, soil ammendment
