Abstract: A field experiment was conducted to study the “Scientific Influence of different sources of Liming materials with and without FYM on Concentration, Uptake & Recovery of the nutrients for Maize crop grown in Acid Soil ” in the village Bajpur in khorda district of Odisha during Kharif, 2013. The soil was ameliorated with three different source sof liming materials (paper mill sludge @ 0.1LR, Stromatolyte@ 0.1 & 0.2 LR and Calcium Silicate @ 0.2 LR) added with soil test based dose with or without FYM. The maximum concentration of the major nutrients follows the order as N>K>P>Mg>Ca>S. The maximum uptake of the ‘N’ (74.8 kg/ha) was observed in Paper mill sludge source applied @ 0.2 LR with STD & FYM but the maximum uptake of the ‘K’ (32.2 kg/ha) & ‘S’ (7.1 kg/ha) was observed in Calcium Silicate source applied @ 0.2 LR integrated with STD & FYM and the maximum uptake of the ‘P’ (13.4 kg/ha), ‘Ca’ (15.5 kg/ha) & ‘Mg’ (6.7 kg/ha) was observed in Stromatolyte source applied @ 0.2 LR with STD & FYM. Among the major nutrients, the recovery of ‘P’ was maximum ranging from 26-66 %, followed by ‘K’ from 22 to 55 per cent, ‘N’ from 17 to 36 per cent and S from 6.2 to 28.7 per cent.The maximum recoveries of major nutrients were recorded with Stromatolyte source applied @ 0.2 LR integrated with STD and FYM.
