Key points Long fallows and green manure crops are valuable management tools that increase soil moisture and nutrition for the following crop.Controlling weeds 100% of the time in fallows preserves maximum soil moisture. Spraying weeds late in this trial equated to lost income of $85.56/ha as a result of lower grain yield and quality.Vetch as...
Will low protein become the new norm? Take home messages Soil tests from throughout the region in 2012 indicate that soil mineral N contents were low in comparison to years prior to 2010, which may help explain why grain proteins were generally low in 2012.Mineral N contents were low primarily due to high rates of...
