    Fruit pulp processing industries generate a significant volume of organic solid waste annually, which is mostly disposed of in landfills, causing environmental impacts. Composting is the main alternative being adopted for disposal, generating leachate, a liquid with a chemical composition that can favor the development of agricultural species, therefore having potential use in agriculture, with economic, social and environmental impacts. Therefore, this research aimed to determine the chemical composition and concentration of leachate (liquid biofertilizer), from soursop processing waste, that promotes the productive and physiological performance of lettuce cv. Veneranda. The experiment was set up in a randomized block design, with five treatments (0% - control, 10, 20, 30 and 40% biofertilizer diluted in water) and four blocks. The chemical composition of the slurry indicated high values for macro (N, P, K, Ca, Mg) and micronutrients (Mn, Cu, Fe, Zn), total organic matter (44,154 mg/L), total organic carbon (4,191.7 mg/L), and humic (10.77 mg/L) and fulvic (1,054.4 mg/L) acids. The application promoted a linear effect (p < 0.05) on plant height, number of leaves, leaf area, total chlorophyll, and shoot mass. A quadratic effect was observed for the index of ‘chlorophyll a’ (Xmax. = 15.58%; Ŷmax. = 22.31), ‘chlorophyll b’ (Xmax. = 25.10%; Ŷmax. = 5.66), shoot dry mass (Xmax. = 24.98%; Ŷmax. = 5.77g/plant) and root dry mass (Xmax. = 22.67%; Ŷmax. = 0.80g/plant), indicating that 22% of slurry has plant growth-promoting properties. The chemical composition of the slurry obtained from the composting process of soursop residue and sawdust presents high concentrations of macro and micronutrients, organic matter, organic carbon, and humic substances, exerting a positive influence on the biometric and physiological components of lettuce. Therefore, it can be used as a liquid biofertilizer, representing a sustainable and economically viable alternative for both organic and family farming.
