Abstract:
The physico-chemical and nutritional study of cow urine, vermiwash, moringa leaf extract (MLE), glyricidia leaf extract (GLE) and pongamia leaf extract (PLE) was undertaken to estimate changes in the essential nutrient elements viz., N, P and K content as well as physico-chemical characters i.e. pH and electrical conductivity of the extracts at an interval of 1^st, 2^nd, 3^rd, 4^th, 8^th and 12^th weeks after storage in comparison to initial content. From the study it was observed that the cow urine and the vermiwash were alkaline in nature while, the plant leaf extracts were acidic in reaction and their acidity and alkalinity were found to be increased from initial to 2^nd and 3^rd weeks after storage, respectively and further it was shifted towards neutrality. The electrical conductivity of cow urine, Vermiwash and plant leaf extracts were declined during the successive storage period. The primary nutrients viz., nitrogen, phosphorus and potassium content of cow urine, Vermiwash, Moringa leaf extract, Glyricidia leaf extract and pongamia leaf extract was found to be decreased throughout the storage period. Therefore, it was clearly noted that, it is better to use fresh form of animal originated sources as well as plant leaf extracts to obtain maximum nutrient benefits of these sources.
