Narrow profit margins for traditional agricultural crops, as well as proximity to many urban markets, has made sod production an increasingly attractive land-use in Delaware.  Sod producers commonly adopt cultural practices that were developed for other turf applications such as golf courses, or in other geographic regions.  Such recommendations may not provide optimal efficiency of nutrient use.  To evaluate these recommendations, we applied rates of 0 lb/A, 100 lb/A, 150 lb/A, 200 lb/A, 250 lb/A and 300 lb/A nitrogen in split applications based on producer’s current practices.  Soil and plant samples were collected from all treatments.  Soils were analyzed for standard fertility (nitrogen, phosphorus, potassium).  Plants were analyzed for standard and trace nutrients.  We collected root mass data to address producer concerns regarding sod strength.  To address customer concerns regarding the “greenness” of the grass, we utilized remote sensing. Preliminary results indicate that there is correlation in the measure of greenness and root mass with ground based remote sensing.  The total root mass was maximized with an application of 150 lbs/A N.
