Resumo: |
This work aimed to evaluate the effect of agroinsudtry wastewater in the oxisoil as disposal of this effluent, mineral composition and production of Tangola grasses (Brachiaria mutica x Branchiaria arrecta) and Vaquero grasses (Cynodon dactylon), 12 cycles, from May 2013 to April 2014. The experiment was conducted in Patos de Minas-MG (Brazil) with three treatments represented by the levels of the effluent, with four replications, totaling 12 parcels cultivated with grass Vaquero and 12 parcels cultivated with grass Tangola, each plot with 3 m². The treatments differ as to the amount of wastewater applied, as follows: Treatment 1: application of water only (control); Treatment 2: 1000 m³ ha-1 yr-1; Treatment 3: 2000 m³ ha-1 yr-1. The application of wastewater increased the rate of accumulation and forage mass of Tangola and Vaquero grasses. The wastewater did not increase the pH, organic matter, P, Ca, Mg, K, S, Al, Na, Cu, Fe, Zn, Mn and B in the soil. Fertigation in forages is a good alternative for disposal of wastewater from agrindustry dispensing final treatment of the effluent. The extraction of soil nutrients by forage from wastewater, contributes to forage production and environmental preservation |
