Abstract
A pot experiment entitled “Effect of humic acid and its sources
in combination with and without zinc on yield and chemical
composition of maize” was carried out at the Dept. of Soil Science and
Agricultural Chemistry, BACA, AAU, Anand during 2011-12. The soil
used for the experiment was loamy sand in texture and deficient in
zinc and medium in nitrogen, available phosphorus and potassium. At
the very first, extraction of humic acid from FYM and vermicompost
was done by using 0.1 N NaOH extractant. This humic acid was used
for both pot experiment and incubation study. In addition to this
comparison of both the humic acids was done for their chemical
properties. Recovery of humic acid from vermicompost was more as
compared to that of FYM. Total acidity, C, H and N was relatively
