Presented by Dr. James Murphy, Rutgers University 

Speaker Bio - Dr. Murphy joined the Extension team at Rutgers University in 1991. He has a Ph. D. in Crop and Soil Sciences from Michigan State University. The goal of his research is to develop best management practices (BMPs) that enhance the stress tolerance, persistence, and environmental benefits of turf. Current research projects include (1) developing cultural practices to reduce anthracnose disease, (2) identifying turfgrass varieties that are more tolerant of traffic; (3) identifying grass seed mixtures that perform better under low input management; and (4) assessing turf persistence and performance under organic management. This research compliments his Extension and teaching activities as well.  In 2010 Dr. Murphy started work on the Professional Fertilizer Applications Certification and Training (ProFACT) program, and this is now the main resource for contractors to learn about best management practices in soil nutrient management and its effects on the environment. Contractors who apply fertilizer professionally are required to be certified. Information can be found at www.profact.rutgers.edu. 

Course Description - This talk will discuss the processes that make N available to plants and thus how the form of N impacts the proper timing of fertilization. This talk will conclude with an update on the NJ certification program for professional fertilizer applicators.

1.  N forms for turf fertilization. 

2. Timing of fertilization as effected by N forms. 

3.  Professional certification update.
