While trying to solve the same problem I’ve inquired before — using shrub sprinkler heads in drip-irrigation system to water narrow side lawn — I am coming to realisation that even if pressure is enough to use them, 13 mm mainline drip tubing could simply not be able to provide enough flow to supply three or four of those at once. So I am looking at alternatives.
One such alternative I am considering is to use drip-system micro-sprinkler heads. They seem to be able to provide enough coverage (some of them can do up to 6 m (20 ft) radius), and with flow rates of 50 to a 120 litres per hour (14‒32 U.S. gph) should be able to deliver water at a rate of quarter to a half that of a shrub sprayer.
In theory it seems like a viable solution, if I simply set them to run, say, three-four times longer than conventional sprinklers to provide enough water. But I had been reading books, brochures and articles on micro-irrigation for a few days now, and hadn’t seen any specific recommendations for that application. I’ve seen some questions like that been asked on gardening forums, but either links were broken, or no useful information were present.
So, is it possible to use above-ground micro-sprinklers to irrigate small sections of turf lawn? Is there limitations on soil penetration by this method of water delivery? Are those sprinklers sturdy enough to withstand relatively heavy use over at least few seasons? Would more drought/resistant grass species be required? How does grass hight affect this type of irrigation?
