Abstract

The field experiment was carried out on maize crop during kharif 2020 at CSKHPKV, Palampur to study the effect of fertilizers and amendments on forms of soil acidity and soil chemical properties in an acidAlfisol. The application of lime with 100% NPK and integrated use of FYM, lime and 100% NPK decrease the exchangeable acidity, total potential acidity, extractable acidity, pH dependent acidity, nonexchangeable acidity and total soil acidity. There was significant increase in the soil pH, CEC, organic carbon and available nutrients (N, P, K, Ca, Mg and S) under treatment 100% NPK + 10 t FYM/ha + lime (full dose through broadcasting) which was at par with 100% NPK + 10 t FYM/ha + lime (1/10th dose through furrow application). All forms of soil acidity observed significant negative correlation with available nutrients and soil properties except soil organic carbon which showed significantly positive correlation.
