Does ESN pay in spring wheat? Results from two on-farm sites in eastern Ontario showed no advantage in grain yield or protein content with the use of ESN in 2011 (see Table 1). There was also no significant difference in residue soil nitrogen levels. As expected there was also no impact in the percentage of […]
Coordinated by: Ian McDonald and Greg Stewart, OMAFRA Background Annually the OMAFRA field crops team surveys a range of corn fields to determine what impact the weather has on the level of residual soil nitrate. In 2012 weather conditions have been almost polar opposite to last year when April was cool and May was wet. […]
Nitrogen (N) dramatically increases the yield of grass stands, as well as forage protein levels. Optimum rates depend on the cost of N, anticipated value of the hay, thickness of stand, moisture conditions, and whether it is pasture or hay. Good grass stands with less than one-third legume, can generally benefit from at least 70 […]
