Evaluación de dos métodos de compostaje como alternativa de manejo de equinaza, sobre la producción de biomasa brachiaria humidicola en campo ecológico gramalote.

Abstract

The storage, transport and disposal of the horse manure has been identified as problematic in the tourism sector, specifically in the provision of the service of horseback riding and equestrian activities; the results obtained in the evaluation of the composting and vermicompost techniques hereby are present on a pilot scale, such as horse manure management alternative, on the yield of Brachiaria humidicola biomass at the “Campo Ecológico Gramalote” in Restrepo-Meta. Differents4 treatments there established, plus the control; T1 (4 kg horse manure + 1 kg vegetable organic material) and T2 (4 kg horse manure + 2,5 kg vegetable organic material); T3 (4 kg horse manure + 1 kg earthworm) and T4 (4 kg horse manure + 2 kg earthworm). The T1 and T2 belonging to the composting; T3 and T4 to the vermicompostaje. Using a T-Student test, were identified significant differences between treatments, taking into account variables as answer pH, temperature, contents of nitrogen, potassium and moisture; after that it was evaluated with a statistician Tukey Test the application effect of the fertilizers obtained on the production of Brachiaria humidicola grass, a fixed effects classification pathway with a dosage of 300 g/m2 in nine experimental units; as a result, despite the fact that that all treatments presented superior characteristics to the witness in physical and chemical variables analyzed, the T4 register optimum quality indices for pH (6,8), temperature (28°C), moisture (55%), N (0,91%) and K (0,84%). Therefore, is highlighted as the best treatment for biomass production with an average height of 21,83 cm compared to control (without fertilization) which obtained averages of 13,92 cm.
