This study aims to determine the effect of lime and nitrogen fertilizer on soil acidities characters, growth uptake corn in total reclaimed potential acid sulphate soil. A pot experiment with a completely randomized design arranged factorial three replications was conducted Greenhouse Indonesian Swampland Agricultural Research Institute (ISARI) from August 2014 December 2015. The first factor rate as dolomite: (i) 25 t ha-1, (ii) 37.5 ha-1. second type fertilizer: (a) control (without N), (b) 115 kg (c) chicken manure 6 ha-1 (the N content is 1.98%) (d) 57.5 + 3 manure. Urea (N 39.76%) used for fertilization. observed variables were properties (pH, Electrical conductivity/EC, available-H, available-Al) before, after reclamation, at maximum vegetative stage corn, plant shoot nitrogen. results showed that process consecutively aeration-leaching soils able increase pH, declining EC value, well availabe bases, available-Al pyrite. application dolomite increased EC, while decreased, its more pronounced higher rate. Application respectively pH 3.29 4.36 4.87, 0.70 mS cm-1 1.51 cm-1, available-H 1.30 cmol(+) kg-1 2.68 1.44 decreased 14.04 4.71 2.66 kg-1. However, these rates not neutralize existing acidity due still being produced out remaining pyrite which active stages. It increasing followed by EC. interaction between significantly influenced height uptake. highest 112 cm 267.69 mg plant-1 respectively, obtained combined plus averages root dry weight 20.97 g 6.40
