GREEN LANDS line
Our Green Lands seed mixes are the result of considerable expertise gained through research and studies within the turfgrass industry.
They are products formulated by highly qualified personnel in close collaboration with world-leading research centers.
Top quality seeds have been a permanent feature in the production of Green Lands.
DEVELOPING NEW TURFGRASS
Developing new turfgrass, in addition to deciding the ideal seeding period (depending on which species is being seeded), starts with preparing the site the turfgrass will be used in order to remedy existing issues and prevent potential ones. Preparation includes clearing the area of obstacles and existing vegetation, tilling the soil, overhauling the terrain, leveling, arranging drainage and irrigation, fertilizing.
Tilling the soil
Tilling allows roots to penetrate the soil and improves soil structure, water retention and gas exchange. If the soil is believed to be compacted, for instance, by heavy machinery, ripping is carried out with the aim of breaking up the slab that is isolating the surface from soil deeper down. Depending on the context, additional techniques, such as plowing, harrowing and disking, can be used and these should be carefully assessed on a case-by-case basis. It is worth bearing in mind, however, that excessive tillage can damage the soil rather than improve it. Generally, for ornamental and recreational turfgrass, measures aimed to adjust any slopes and allow drainage so that water does not build up is sufficient soil preparation.
Fertilizing the site
During the tillage phase, nutrients and soil improvers (compost, manure) can be incorporated into the soil both to improve its structure and to gradually release nutrients. Quantities should be determined based on soil analyses.
On the surface, immediately before the final leveling and seeding is carried out, starters containing nitrogen and phosphorous are distributed, which are vital nutrients during early plant development. Starter fertilizer is light and the quantity of nitrogen is typically between 1 and 2 g/m2.
Leveling
The area must be flat to allow water to drain. In general, slopes should always move water away from buildings. A 1-2% slope is enough.
Next, refining is carried out which prepared the seed bed, often the same day as seeding. On smaller surfaces, it is done by hand using a rake. Alternatively, for larger areas it can be done using wire mesh attached to a tractor.
Seeding
Once the ideal seeding period has been identified, based on the variety being used, seeds can be spread by hand on small surfaces, or using a drop seeder or rotary seeder for even results on larger areas. It is best to do this when there is little wind.
For seeding on playing fields or for re-seeding, a tractor-driven row seeder is used with less than 2.5 cm between the rows. The tractor-trailer calibration should always be trialled on a test surface.
Another method is hydroseeding, which may be preferable on slopes or irregular shaped terrains. In this method, the seeds are mixed with water, plant fibers and adhesive. The seed mix is continuously stirred in a tank and sprayed at a high pressure onto the terrain.
