Farmers could increase maize yields by as much as 15% dry matter by applying sulphur alongside nitrogen.
Speaking at Syngenta's maize conference in Shifnal, Shropshire, independent consultant George Fisher said sulphur deposited from the atmosphere was now so low due to cleaner industries that even maize crops are responding to applications of the nutrient.
Modern grass varieties and high quality mixtures have the potential to deliver superior yields and excellent feed values, but often grassland management and basic nutrition is overlooked, and new leys fail to deliver their full value.
