Liquid organic fertilizers are made with techniques that are not new and are practiced in various parts of the world, but its use as foliar fertilizers has spread to many countries without a scientific basis to describe their mode of action and demonstrate their effectiveness. In the case of the Andean region of Bolivia, anaerobic biological presents issues that are not finally settled and that have to do with the process of anaerobic digestion, processing time, quality and use, and inputs that contribute to the solution, they are related to obtaining a liquid organic fertilizer with the presence of oxygen. In this context an aerobic method with compost, humus and peat pre-humified substrates, as a result you have the liquid manure aerobic made with substrate compost (AOLA C1), presented a nitrogen content available assayed 30 mg N-NO3 / liter, exceeding the aerobic liquid organic fertilizer made from worm castings substrate (AOLA-HL1) presented 4.4 N-NO3 / liter. In phosphorus, AOLA filed C1 P-PO4 13 mg / liter, being slightly smaller than AOLA-HL1 that took 16 mg PO4-P / liter. AOLA potassium C1 showed the 439 mg K / liter, exceeding the AOLA-HL1 presented 54 mg K / liter AOLA; AOLA treating the peat substrate was discarded by turbidity and lack of biological activity. Based on laboratory data analysis and chromatographic evaluation established that the AOLA C1, is a liquid organic fertilizer aerobic quality and the AOLA-HL1 is a liquid organic fertilizer aerobic moderate quality. The evaluation of the effect of foliar fertilization of these two liquid fertilizers aerobics performed in a pot experiment, three doses tested 10%, 20% and 30%, on vegetable chard, spinach, parsley and lettuce. No statistical significance was found but if digital, the first three plants showed a better effect of AOLA C1 (compost substrate) in the ratio 20%, with a better engraftment per plant, increased plant height and higher leaf biomass; Lettuce best responded to a ratio of 10%, possibly because it is a short vegetative plant available nutrients and demanding period in a diluted medium
