Summary Not Available – First paragraph follows:
One application of plastic coated nitrate and ammoniacal nitrogen produced acceptable turfgrass for a nine-month period in these tests. This was comparable with turf produced by six low application rates of ammonium sulfate over the same period. One application of all other nitrogen sources produced acceptable turf for three to four months. Further work is needed with different grass genera and soil types.
