Yay! Soil Association Calls for a Ban of Glyphosate Weedkiller There were about 1.4 billion hectares of actively farmed, arable cropland worldwide in 2014. Across this landmass, there were an estimated 747 million kg of agricultural applications of glyphosate. If this volume of glyphosate had been applied evenly, about 0.53 kg of glyphosate could have been sprayed on every hectare of cropland on the planet (0.47 lbs/acre). https://www.permaculture.co.uk/news/0202166961/soil-association-calls-ban-glyphosate-weedkiller
