Abstract
A comprehensive field experiment was conducted to study the â Effective Influence of various sources of Liming materials on Chemical properties of the soil for Maize crop Grown in Acid soil â in the villages Haladia, Jatni and Bajpur in Khorda district of Odisha during Kharif, 2014. The soil was ameliorated with three different sources of 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. Application of liming materials irrespective of the sources neutralized soil acidity increased from a level of 4.94 to a level ranging from 5.11 to 5.55 and maintained for 14-35 days when lone sources are used. Combined use of liming materials with FYM increased the pH to a level ranging from 5.65-6.08, which was maintained for a period of 28-49 days after application. The acid neutralizing efficiency of liming materials followed the order: ST@0.2LR>CS@0.2LR>PMS@0.1LR>ST@0.1LR. Appliaction of lone sources of liming materials alone increased the CEC from 6.39 to 7.37 cmol(p+)kg-1but the combine application of liming materials with FYM increased the CEC from 7.38 to 8.03 cmol(p+)kg-1.
