With the aim of evaluate the viability of the use of non-conventional materials as fertilizers, it was tested, under controlled and fields conditions, the effect of the hydrolyzed residue from the Fishery industry in solubilizing Phosphorus rock and Bone ash (30 and 22 % P2O5 respectively). This residue was incubated with different levels of Phosphorus (P) concentration (200, 400 and 600 mg kg-1 P2O5). As source of Nitrogen (N) was used the same Hooves and horn meal (HHM – 13.5 % N) under different levels of treatment 100, 200 and 300 mg kg-1 N. An additional control treatment was added, as well as, a treatment with inorganic or traditional fertilizers. For the field experiment, only conventional fertilization, Hooves and horn meal, Hydrolyzed residue as foliar fertilizer and a control treatment without fertilizer were used. The treatments were distributed following a completely randomized design, using river soil as substrate. Corn (Zea mays) was selected as the indicator plant for the experiment, and it was cultivated for 8 weeks in order to measure height of the plant, biomass production and nutrients extraction (N, P, K). It was used water with low content of salts. As results from the controlled conditions, there was not combined effect of the application of Bone ash and Phosphorus rock incubated with the HHM among the treatments established. When the analyzed is done separately, responses closely to the conventional fertilization were found. That is found especially in treatments with HHA both, in the height of the plant and the biomass production. Regarding to the nutrients extraction (N, P, K), the tendency found for the biomass production is followed as well for this variable, applied only in lowest level (100 mg kg-1 N y 200 mg kg-1 P2O5). As results from the field experiment, the efficiency of the HHM as sources of N was confirmed, as well as a small contribution by the hydrolyzed residue. As additional information, it was reported a Unitarian extraction for every ton of grain, nutrients ranging within 21.4 – 23.8 kg N, 12.1 – 12.3 kg P2O5 and 20.6 – 23.6 kg K2O. As main conclusions of these experiments, it is possible to have those non-conventional materials as potential alternatives for crop fertilization. However, more research is needed in order to confirm the results obtained in this experiment.
