The big show, anchored by the Golf Course Superintendents Association of America (GCSAA), was held Feb. 23-Feb. 26 in San Antonio, with most activities occurring at the Henry B. Gonzalez Convention Center. Here are some of the things we saw and heard at the show:

Anthony Boone, vice president of communications and marketing for Ostara Nutrient Recovery Technologies, said he has been hearing more and more from superintendents about the sustainable aspects of nutrients. Ostara markets, Crystal Green, a slow-release fertilizer made from recovered phosphorus and nitrogen from municipal and industrial wastewater streams. Incidentally, wastewater recovery in the wastewater treatment sector is growing as Ostara’s business attests. In the next 18 months, the company will open six more plants to go with the seven it already has.
