Fertigation of sweet sorghum (Sorghum bicolor L. moench.) in laboratory and nursery assays with treated vinasses of hydrated ethanol of UASB reactor
Vinasse is used in crop fertigation indiscriminately, however, this wastewater generates serious environmental damage as the reduction in crop yield or even its death in the short-term and acidification, decreased oxygenation, increased organic load, accumulation of phenols in soil in the medium and long term. The aim of this study was the fertigation sweet sorghum (Sorghum bicolor L. Moench) in laboratory (bioassays germination) and growth in nursery treated with hydrated ethanol stillage from a UASB modified, in order to improve its chemical properties and use them to 50, 75% (diluted) and 100% of treated vinasse (TV50, TV75 and TV100 respectively). The raw vinasse (RV) had the lowest percentage of germination in seeds of sweet sorghum in laboratory tests (14% in 8 days) compared to the control treatment where 94% of germinated seeds. Growth of seedlings in the nursery with RV treatment was lower than in other treatments and after 13 days the plants completely stopped growth and died.
