   Have had D&F the last few years with great results on old pushup greens. Cost is very high and if we have a cool spring healing takes some time. I'm looking at using Dryject Maximus in the off years that we do not D&F. Cost is much lower and disturbance seems less and quicker to heal. Any opinions would be appreciated.

   I am thinking the same thing...also can alternate fill materials for different purposes...

   We are doing a Drill&Fill this March on all greens except a little chipping green where we will demo the DryJect Maximus. I'm curious to see how both processes perform side-by-side.

   Dryject Maximus on the left in green. Standard on the right

   Did drill n fill at our course for 3 falls and during our regrassing, like the process. Got the sand down deep but still a mess left to cleanup. Did a demo of dryject maximus and was very impressed. The fracturing of the profile and still the ability for the sand to get deep into the profile similar to drill n fill. Cleanup was left to just dragging the excess sand around when dried. Haven't done maximus or drill n fill since regrassing our greens but if I was to do again I'd do maximus. Similar time need to complete but much less labor as you're not having to clean up the spoils pulled up from the drills. I've also wondered about the "glossing" of the holes during the drill n fill process. Rotation of the bits smoothing off and possibly sealing off the cavity that is created not allowing for quick water movement out of the cavity. Maximus fractures and you sometimes see the sand spider web out from the main hole to fill other areas, would assume better drainage. Just may thoughts.

   Edward,
   I have had both drill/fill and dryject. Last spring we did maximus on practice green. Although I loved the drill/fill, I dont think I can justify it after witnessing maximus results. The pics around the internet that you see of the maximus results dont lie. We have found that if we deep solid tine greens before maximus or dryject, we get even better penetration with maximus machine. This spring we will do all greens with maximus both spring and fall in conjunction with our usual double aerationw/ pro core. hope this helps.

   Thanks Ryan, we have used D&F for the last four years on all our greens except the practice greens. Prior to this we would aerate with 60x3/8s coring tines twice a year, Vertidrain in fall and solid tine during the summer. When members notice the much firmer conditions that result with the D&F it is very gratifying. We are going to skip this season (last four years have been double D&F 31/2x7" spacing) so instead I think I will get the Dryject Maximus tried on some greens after we vertidrain as you suggest.
   
   We found an impressive increase in water movement with D&F, was this apparent with the Maximus treatment?...thanks ed

   Hey Edward we did eventually see an increase in water movement. What we also noticed was an increase in hydrophobic conditions on the greens surface. I am in the middle of finding out why. At first the assumption was the large amounts of kiln dried sand injected into the root zone. Now im thinking it may have to do with either less organic matter or bicarbs. For now We remedy the situation with a half rate of penetrant/retaining agent.

   Just finished aeration a couple of weeks ago with 3/8" and on one of our putting greens had the DryJect Maximus demo. Used a couple of tons of sand for the 4500 sq.ft. green and procedure was quick with easy cleanup. Cup cutter shows blast of sand much larger than the 1/4"x1" slot entry point. Great weather and all healed in 10-14 days. Looking forward to trying on all greens this fall since budget isn't there for D&F. May do the same procedure with regular topdress, aerate with coring tines weather permitting. ed doda barrie cc

    Does anybody who has used dryject have any thoughts on what it does with the displaced material? Does it push soil downwards, or move it laterally? Is there any thought that it could force material downward into gravel or drainage pipe?

    You get a slight bit of heaving with the Maximus process. At least on sand based greens. Nothing to worry about since it easily rolls out.

    I've dryjected 5 times in 4.5 years here on a "modified push up" green with drainage at 50 yrs old. Each time I learn something different with the dryject. The last dry ject I wanted to get the sand in the top 3-4 inches so I had them adjust pressure settings etc. to focus sand at the top vs deep. It worked well, however the pressure and water brought to the surface "dirty water" which seemed to be full of fines. In hind sight I should have washed the green off with hoses to insure I was removing that potential fine material. The other thing i'd do differently is dryject a week in advance or at least do it before you core aerify. I've been coring/sanding - then dryjecting. It can push the sand and water back up through the aerification holes.
