Following its use at the 2014 World Cup, DLF has been chosen to help Brazilian groundsmen prepare their stadiums for the football element of the Olympics, covering the venues hosting the women and men's football and rugby sevens tournament.
August is Brazil's cool season, so turf preparations must overcome the grasses' natural dormancy. Building on technology used in 2014, the turf was overseeded with a special mixture developed through DLF's plant breeding research. The mixture, which has proven to be optimal for the Brazilian climate and geography, provides a uniform playing surface for all matches of the tournament. It includes the top-performing perennial ryegrass varieties and DLF's trademarked 4turf technology.
Søren Halbye, chief commercial officer at DLF Group, said: "We are proud to offer our grass seed technology for this major sports event. Based on the excellent pitch performance at the 2014 World Cup in Brazil, we are confident that the pitch quality will fulfill the high expectations."
DLF is working closely with the Brazilian grass specialists and professional contractors. Alexandre Vieira dos Santos, part-owner of Greenleaf Gramados which is installing most of the Olympic pitches, said: "Our main challenge is to get all pitches looking good and into perfect shape during our winter season. Brazil is a huge continent and the logistic challenges of getting products from the North to the South are immense.
"Back in 2013 at the Confederation Cup, prior to the Word Cup in Brazil 2014, we identified the high-performing ryegrass mixture from DLF to have the best overseeding performance. The key features we consider are the best adaptability to different climate zones and a good shadow tolerance, which is critical given the architecture of the stadiums."
Some of the pitches will host 10 games over 10-14 days, dos Santos said.
"We have been working with the sports perennial grass seed mixture from DLF for several years now, and we know we can rely on its performance and high wear-tolerance during the competition."
