Predictable protein levels getting the nitrogen right

Plain text source: 
Predictable protein levels getting the nitrogen right.. In 2012 low soil nitrogen and subsequent grain protein were compounded by: wet summer fallows leading to waterlogging and denitrification; depletion of subsoil mineral nitrogen reserves by crops in 2009, 2010 and 2011; a decline of organic matter in the soil due to continuous cropping; and lack of legumes in rotations to supplement the decline in nitrogen from organic matter... If we want a return to high protein grains, we need to work out how to get that nitrogen back in the system," Dr Dowling says...
