Changes on seed bank composition of Flooding Pampa rangeland by the use of glyphosate

摘要：

To increase winter forage production of native rangelands of Flooding Pampa, a technique based on spraying glyphosate herbicide in late summer has been widespread during the last decade in this region.Glyphosate eliminates green vegetation growing in late summer, improving germination and establishment of cool season (C3 ) annual grasses, that enhaces winter forage and meat production.We postulate that annually application of glyphosate would reduce the seed bank of species that vegetate during summer, like perennial grasses and legumes, decreasing floristic diversity and deteriorating the rangeland.
