There are ever more applications for the use of injection bars in summer too. We have put this technique to successful development of an initial series of football pitches. Listed below are several tasks that may be performed in a single operation: • Aeration • Scarification • Fertilisation • Irrigation • Sand perfusion Games are not affected since all operations may be performed at night; a game can then be played the following day with virtually no limitation whatsoever. A further advantage is that water with diluted fertiliser under precise pressure may infuse the roots directly. Up to 50% of water requirements result from this method of injection. In addition, the flow being injected causes a soil exchange of natural nitrogen at the grass roots. Greenkeepers may determine the desired root length by varying the water pressure. Any type of liquid fertiliser at any dosage may be incorporated in the water by a special ceramic 3-piston pump. A substantial saving in fertiliser is achieved by applying it directly to the roots, with the attendant environmental benefits. |
