The general objective of this work was to evaluate the feasibility of preparing an accelerated liquid fertilizer (ALA) from weeds. Weeds were collected from UNALM crop fields and 20 treatments were prepared in the laboratory with different proportions of weed-water, molasses and B-Lac mix. The mixtures were evaluated for five days by measuring pH, titratable acidity percentage, humidity percentage, absence of odors, fungi and yeasts for the choice of the best treatment. The T8 mixture (85 % weed-water mixture, 10 % molasses and 5 % B-Lac) showed the best characteristics. The treatment chosen was reproduced on a pilot scale, where in addition to the parameters evaluated in laboratory, a compositional and microbiological analysis was performed to characterize the biofertilizer obtained; and a germination and phytotoxicity test. In the field, the effect of the application of the biofertilizer on lettuce plants was evaluated using two application modes, two frequencies for each application mode and a control without application. The variables evaluated were yield, fresh plant weight, plant height, head diameter, percentage of dry matter and nitrogen, phosphorus and potassium content in dry matter. The results of the laboratory and pilot phase were analyzed in a completely randomized design (CRD) and the results of the field phase, in a randomized block design (RBD) with five treatments and four blocks. No significant differences were found between treatments, except in the percentage of dry matter and potassium content, where T2 (foliar application twice a week) showed the best result. Through the homolactic fermentation process it was possible to reuse the weeds for the development of an accelerated liquid organic fertilizer. Physicochemical characteristics such as pH, lactic acid, microbiological analysis and nutrient content indicate its potential as a biofertilizer. ALA applications indicate foliar application twice a week as the best treatment
