Nitrogen Optimization System ® SiteOne Landscape Supply introduces LESCO NOS (Nitrogen Optimization System). It is the industry's first fully incorporated DCD-stabilized nitrogen fertilizer that prevents nitrogen loss. The exclusive LESCO NOS technology slows the rate at which nitrogen is lost to environmental leaching and volatilization. Keeping nitrogen in an ammonium form longer helps plants efficiently use nitrogen when needed. Professional turf managers will optimize both nutrients and dollars by slowing the rate at which nitrogen becomes available to the turf, improving greening longevity between applications to optimize application labor and prevent call-backs. SITEONE LANDSCAPE SUPPLY, 800.748.3663, WWW.SITEONE.COM Snow Pusher SnowEx® has introduced its POWER PUSHER TE snow pushers for skid-steers, wheel loaders, backhoes and tractors. Available in 8- and 10-foot-wide models with large carrying capacities, the new snow pushers feature steel trip-edges to deliver cleaner scrapes and help operators get down to the pavement. The steel trip-edges on these models use four extension springs, along with two outer double ribs at the trip springs to handle heavy-duty loads and stresses. Side-support posts help prevent bending from hitting curbs or other accidental impact. SNOWEX, 800.725.8377, WWW.SNOWEXPRODUCTS.COM W W W. PA R K S A N D R E C R E AT I O N .
