Intense utilization of humic substances in agriculture has generated a lot of interest among producers, consumers & regulators for an accurate, reliable & cost effective method to quantify humic acid in raw ores & products. Humic acids are dark coloured fully decomposed remains of plant and animal organic matter. They play a leading role in several chemical, geochemical and geological processes. Humic substances also promote plant growth and improve the organic matter status of soil and soil fertility. Here we present a thoroughly validated method for the extraction of humic acid from dry cow dung powder. The proposed methodology is found to be simple, cost effective, and eco-friendly. The process investigated herein provides a promising solution to many global environmental problems.
