Piesková injektáž GRADEN špeciálne ošetruje vrchnú vrstvu trávnikov do hĺbky cca. 3 - 4 cm a stáva sa ďalším veľmi efektívnym nástrojom pri ošetrovaní trávnikov. Ako časť programu údržby trávnika sa stáva doplnkom už existujúcich operácií ako vertikutácia, hĺbková aerifikácia, hollow coring (špuntovanie), top dressing...
Zavedenie novej pieskovej injektáže Graden posúva údržbu trávnikov na úplne novú úroveň, pretože piesok sa po prerezaní okamžite ukladá do profilu mačiny, a tým rýchlo spevňuje povrch, skracuje čas regenerácie trávnika, čím vytvára pre semená ideálne prostredie. Tým, že presne vypĺňa drážky, zabezpečí, že top dressing sa umiestni presne tam, kde treba. To ocenia hlavne hráči golfu, ktorí chcú nerušene hrať počas celého roka.
Aplikovať sa musí absolútne suchý piesok, ale pracovať sa dá aj na vlhkom podloží.
Po ošetrení trávnika strojom GRADEN odporúčame urobiť dosev. Semená sa dostanú do žliabkov, kde majú ideálne podmienky na rýchle a aktívne klíčenie. Na záver je vhodné jemné zapieskovanie.
Možnosti výmeny rôznych čepelí - s hrúbkou 1, 2, 3 mm a rozstupmi medzi jednotlivými nožmi 9, 13, 25, 30 mm.
Čepele a riadkovače rozličnej šírky sa môžu nasadiť na štandardný hriadeľ v ľubovoľnej konfigurácii podľa individuálnych potrieb. Pri ľahkom, ale častom zásahu na odstránenie plsti sa 1 mm čepele môžu umiestniť tesne vedľa seba.
Štandardná konfigurácia je 1,2 alebo 3 mm čepele s riadkovaním 25 mm, ale veľkosť čepelí a riadkovanie možno nastaviť podľa potrieb trávnika.
Technická špecifikácia stroja na pieskovú injektáž GRADEN:
Záujemca o pieskovú injektáž si musí zabezpečiť absolútne suchý piesok (musí sa sypať ako soľ) a vlastnú pracovnú silu na dosýpanie piesku a čistenie trávneho koberca po aplikácii (2 - 3 osoby).
Čas potrebný na ošetrenie greenu je odlišný v závislosti od hĺbky záberu a veľkosti greenu, ale malo by to byť medzi 45 a 60 minútami.

Špuntovanie:
Graden:
Hra s číslami
Agronómovia USGA v článku, ktorý napísali, tvrdia, že každý rok by sa malo ošetriť asi 15- 25% trávnika. Závisí to od mnohých faktorov a kontrolovaní nahromadenia organickej hmoty. Ak je táto vrstva hrubšia, horeuvedené percentá by mali byť vyššie. Nasledovná tabuľka uvádza porovnanie medzi postupmi špuntovania a Graden pri ošetrovaní povrchu a odstraňovaní plsti.
