An investigation was carried out at College of Agriculture, Vellayani, Kerala, to evaluate the keeping quality shelf life and nutrient content of organic liquid manures. The results of the study revealed that the shelf life of promising organic liquid manure could be improved by bringing the pH to slightly acidic condition (6-6.5) by the addition of lime. Autoclaving helped to remove the foul smell of liquid manures without causing any reduction in nutrient content.
