Re: Tap timer recommendations 8Aug 27, 2010 5:55 pm Thanks Fu - I'm not sure how permanent it's going to be - I'm most worried about my fruit trees getting sufficient water if we go on holidays. I actually like hand watering during the way (it lets me get some much needed Vitamin D!) I'll take those brands to my local irrigation shop and check them out. After 4 years - we're in! Re: Tap timer recommendations 9Aug 27, 2010 8:24 pm Hand watering is the most inefficient means there is to water plants. water is saved in a city because no one can be bothered to do it. Re: Tap timer recommendations 10Aug 28, 2010 8:01 am Really? Wow - I found that I get much more even watering of my lawn if I do it by hand - though it does take 2 hours! (compared to a sprinkler) After 4 years - we're in! Re: Tap timer recommendations 11Aug 28, 2010 12:31 pm Studies done in Qld last year or the year before found massive improvements in water savings with irrigation. At the same time a good mate of mine was doing one here in the west and found almost identical results. This is also something that nurserymen have long been aware of. I'm not talking trivial saving either. 1500% in a few cases. In most it is more like 300-500% less water used and with negligible surface run off. A further saving can be made by programming several short waterings as opposed to one or two long waterings. That figure is around 25%. now use junk irrigation and this is not the case but use the types I speak of and that will be very different indeed Re: Tap timer recommendations 12Aug 28, 2010 12:33 pm Fu Manchu What we are learning here in WA and educating the public on are very different form the many long held traditional concepts of gardening. What is happening as a result of that is having serious consequences on the environment. Water management in retail nurseries and garden centres : Nursery and Garden Industry Australia Scheduling irrigation to maximise efficiency : Nursery and Garden Industry Australia Water use in the nursery and garden industry - results of the 2006 Water Use Survey : Nursery and Garden Industry Australia and we can thank I am pretty sure Dr John Colwill for this If not then the Water Corporation Now granted the soil is different here but the concepts are the same and considering that WA leads Australia in domestic water management and public education strategies then it is pretty solid info. John Colwill's work has been copied around Australia by a few state governments. Not all plant roots absorb water. They also play a major role in structure. The magic layer of soil is mostly 30- 40 cm deep in regard to where the overall action is happening. ie, the living layer of soil. Re: Tap timer recommendations 14Aug 28, 2010 12:39 pm When we hand water, we are applying water at rates far higher than the soil can absorb. This leads to increased nutrient leaching and surface run off. Also nearly every person uses nozzles that are designed more for people than for applying water efficiently. Nearly all mist water into the air at enormous rates. Just watch someone in the early morning with the sun behind them as they water, You'll see just what I mean that will depend on the kitchen bench depth. you'll have to specify it so it allows for both the tap and the sink 1 7394 7 5139 Brass or 2) Stainless steel made - which Kitchen tap is good for drinking.Brass kitchen taps in Australia contain lead… 0 6736 |
