Humic acid on soil microbial population

The present investigation was carried out at the Vegetable Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh (India) during Rabi of the year 2009 and 2010 on alluvial soil to assess the effect of Pseudomonas fluorescens and humic acid in combination with three different levels of mineral fertilizer fertilizers on microbial dynemics in alluvium soil. All inoculated treatments in both years of experiment gave significantly greater microbial population and enzymetic activities compared to control at harvest of cabbage crop.
