An experiment was conducted to study the nutrient content of arecanut husk and its composting by employing efficient microbial consortia consisting of cellulolytic and lignolytic fungi and enrichment of compost with beneficial microorganisms viz., free living nitrogen fixer, Azotobacter and phosphate solubilizer at College of Horticulture, Sirsi for three years (2012-13 to 2014-15). The initial C: N ratio of the husk was 84.71 which had decreased to 15.53, 18.41 and 17.92 during 2012-13, 2013-14 and 1014-15 respectively on 90 days after composting with microbial consortia (T3). However, N (0.70 to 1.40%), P (0.23 to 0.77%), K (1.16 to 1.46%), Zn (90 to 135ppm), Mn (251 to 277ppm), Fe (30 to 60ppm) and Cu 230 to 287ppm) contents of the compost were found to increase during 90 days composting. The results of the experiment had clearly indicated that the nutrient content of the compost had increased with increase in the age of the compost up to 90 days in arecanut husk residue, inoculated with microbial consortia along with cow dung slurry and glyricidia (T3) as compared to arecanut husk inoculated with microbial consortia along with cow dung slurry and 3% urea solution (T2) and uninoculated control, cow dung slurry and glyricidia (T1).
