Urban Farm DB summary
Liquids derived from vermicomposting of pre-composted cow dung—vermiwash and vermicomposting leachate—were diluted to prevent leaf scorching and applied to sweet potato as a foliar treatment. Chemical analysis confirmed the presence of plant nutrients, and increases in chlorophyll content (chlorophyll a, b and total) and improved nutrient distribution in sweet potato leaves were observed. The results indicate vermiwash and vermicomposting leachate have potential as organic foliar fertilizers, and their application in field-scale urban farming fertigation is feasible, though enriching their nutrient content further would require adding other nutrient-rich substrates.
