Influence of Ageing on Quality of a Liquid Organic Formulation Used to Increase Soil Fertility

Dr. Mamatha A


Use of chemical fertilizers and pesticides has drastically affected the soil quality and also the products obtained leading to a number of diseases. In order to sustain the nutrient quality of the crops, thus protecting the mankind from falling prey to the disease causing chemicals retained in the crops, a system of natural farming using a liquid organic formulation providing replenishment to soil nutrients and natural regeneration was used.

Further, a study on influence of ageing on quality of a liquid organic formulation used to increase the nutrient content and fertility of the soil was carried out at Department of Pharmacognosy, KLE College of Pharmacy, Bengaluru, India. The main objective was to find out the shelf life of Liquid organic formulation by analyzing its physical and microbiological properties. Liquid organic formulation was stored for 1, 7, 14, 21, 28, 35, 41 and 49 days. Change in colour, odour, pH and microbiological activity of the soil fertility favoring organism was carefully observed during the storage period. The microbial load which were large in number and motile, gradually reduced during the 35 day study and later on was found non motile and dead in the 41 day study. The investigation revealed the possibility of storing Liquid organic formulation upto 35 days without quality and microbial deterioration. So a shelf life of 35 days can be fixed for usage of the liquid organic preparation.
