consistency of plasticine.” The original greens were not good enough and the contractor was forced to return to construct them properly, he adds. They deposited a pea gravel layer at about eighteen inches depth, then sand, then put on very fine sand on top. Under a rolling programme of


improvements, three years ago Colin and the team began inch-wide drills, adding topdressing (kiln dried sand) down to twelve inches to gradually build up a higher quality


profile. “Slowly, but surely, we’ve developed it to 4/4.5 inches depth, but we really need twelve inches for a decent rootzone and this will take years to achieve. We have a continuing struggle to keep the greens dry and firm. In fact, most of the fairways drain better than the putting surfaces.” “A green tells you if it’s suffering. You must get out there and look, but also use the data as a call to action. We’re tickling them all the time to improve performance.” “The original work of drill and fill may


have cost us up to £15,000, but definitely improved conditions. Pumping plenty of air into the greens has certainly firmed them up.” Their Sisis Aeraid tine releases compressed air at about four inches and the team use it throughout the traditional playing season and in winter. “Compaction was the main problem when


I first came here,” he continues. “Lots of areas have improved because of introducing air into the ground. So many good things come from aeration. More air means less


PROFESSIONAL OVERSEEDING RESULTS AT AN AFFORDABLE PRICE


All turf suffers from the consequences of ageing and as the years go by, grass plants die and species disappear, reducing the density of the growth. As a result, more and more unwanted guests such as weeds and thatch get the chance to become established in the turf. Scarification and certain herbicides can briefly interrupt this decline but the only way to solve the problem completely is to renovate the turf and the Eliet DZC600 Overseeder makes high tech overseeding possible at an affordable price.


OVATIVE OVERSEEDING TECHNOLOGY


1. CUTTING OPEN THE SOIL The cutting blades at the front of the machine cut open 8mm (0.3”) to 15mm (0.6”) deep grooves in the soil of the turf in preparation for the grass seed.


2. REMOVAL OF EXCESS SOIL The blades rotate over the top and cast the soil in an arch to the rear of the machi- ne so that it does not fall into the newly cut grooves.


3. PRECISION SOWING A clever and compact seed distribution system, Helix Seed DuctTM


der the projected excess soil into small funnels leading to discharge channels precisely located above the clean grooves.


, carries the seed un-


4. INJECTION A small air pressure generator blows air through the seed funnels so the seed is blown while it is being distributed. This helps the seed to settle faster and with more precision in the grooves.


5. ROLLERS The powered rubber roller immediately follows the seed distribution process and ensures that there is good contact between the soil and the seeds by pressing the earth down.


6. COVERING THE SEED The flow of projected excess earth falls just behind the roller on the sown area. The earth covers the seedbed and provides a protective layer for the seed, increasing the


chances of germination and growth.
