Maryland Department of Agriculture issued the following announcement on Feb. 14.
The Maryland Department of Agriculture today announced that farmers who planted small grains for harvest last fall may “top dress” these crops with commercial fertilizer beginning February 15, as long as ground conditions remain favorable and in accordance with their nutrient management plans. The determination follows Maryland’s nutrient management regulations and is based on research conducted by University of Maryland plant experts. As a reminder, manure may not be applied to fields until March 1.
Each year, University of Maryland researchers examine soil temperatures and crop growth over the winter to estimate when small grains will emerge from dormancy. According to data collected by University researchers, commercial fertilizer may be safely applied to small grains beginning February 15. At this time, these plants will have absorbed all available nutrients in the soil and will require additional nutrients to keep growing. The University cautions farmers, however, to check individual field conditions and avoid running heavy equipment across saturated soils.
The University recommends split applications of spring nitrogen with the first application occurring on or soon after February 15 and the second application when the crops begin to joint.
For additional information on Maryland’s nutrient application requirements, contact the department’s Nutrient Management Program at 410-841-5959. Farmers with fields that are not suitable for harvest should contact their crop insurance agent for guidance.
