Kao-Kniffin Lab featured in Landscape and Irrigation

Kao-Kniffin in Landscape and IrrigationVia Michelle Sutton (MS Horticullture ’00), Editor, Taking Root, the blog of the New York State Urban Forestry Council:

Jenny Kao-Kniffin’s lab is featured in the September 2014 issue of the trade journal Landscape and Irrigation. (See page 22.)
In the article, Kao-Kniffin offers advice for how grounds people can manage turf in light of New York’s 2010 Child Safe Playing Fields Law, which restricts the use of conventional pesticides on K-12 school grounds, playing fields and daycare centers.

“Some contractors go overboard with adding fertilizers. This can result in extensive phosophorus application, whereas nitrogen should really be the focus when it comes to turf density in most sites,” she says.

The article also details research by horticulture PhD candidate Grant Thompson, who is comparing polycultures of turfgrass species with monocultures. “In the polycultures, we found some moderate increases in biomass and some moderate retention of nitrogen,” he says. He also found more diverse bacterial and fungal communities in the root zones of the polycultures.

On a related note, research at the Horticulture Section’s Urban Horticulture Institute was recently featured on the Taking Root blog, which has replaced the New York State Urban Forestry Council’s print newsletter.
