Soil Greenhouse Gas Emissions in Different Pastures Implemented as a Management Strategy for Climate Change

The increase in global average temperature has significant implications for food security and agriculture production. Grass species adapted to new climate scenarios are essential the success of livestock aim this study was evaluate different forage species, providing animal feed during critical dry periods as an adaptation strategy grazing systems, its greenhouse gas (GHG) emissions. field experiment conducted September 2015 2017, with four treatments (n = 5, completely randomized block design), including two perennial forages, Bromus valdivianus (Bromus), Lotus corniculatus (Lotus), alone a mixture pasture (Br/L). As control treatment, commonly seeded by farmer used (hybrid ryegrasses + Oat, Control). One-half plots nitrous oxide (N2O) methane (CH4) measurements, remaining half destructive soil sampling. Gas fluxes were measured using static chambers technique. Cumulative emissions N–N2O, C–CH4 CO2?eq not affected treatments, averaging 1.7 kg N–N2O ha?1, 3.2 ha?1 635.5 CO2 respectively (p > 0.05). However, emission intensity tended be lower Br/L compared other 0.06) second year, while yield greater < showed (first years) highest metabolizable energy lowest crude protein content. Our results suggest that mix management would promote farm adaptation, given it favors at year. This inclusion also reduces from grassland soils well favoring capture. determined regulated variables, mainly moisture temperature. Extension knowledge transfer should provided farmers account potential adoption barriers, such low short-term yield.
