We not only depend on water, we also pay for it. So, why not put that rainwater to use?
A few posts ago I spoke of our receiving just a little rain, a blessing considering we are in drought mode. It got me thinking about my comment that plants tend to thrive so much better on rainwater...........why?
My research shows a few considerations. Rain may contain a variety of nutrients: phosphorus, sulfur, ammonium, nitrate, even metals like iron and manganese.
Fresh normal rainwater is naturally mildly acidic, because it absorbs carbon dioxide from the atmosphere and makes a weak carbonic acid solution.
My understanding is that the acidity of rain varies quite a bit, depending on the season as well as geography, but it is always at least mildly acidic.
Electric charges from thunderstorms also dissolve a small amount of nitrogen into the rainwater in the form of nitrates
Most plants are better able to take up nutrients when the pH is between 6.0-7.2, so it does seem logical that when you've got fresh rain saturated soils, the plants are able to take up more nitrogen and other nutrients than they are when watered with tap water.
The other factor that makes rainwater different from tap water is the hardness, which is a measurement of minerals in the water.
Rain is "soft" water, in that there are no minerals deposited in it, while the ground water from rivers, lakes and reservoirs that becomes our tap water absorbs some of the calcium and magnesium in our soils, and is "hard" water.
These calcium deposits raise the pH (making our soil more alkaline), which makes it harder for the plants to take up certain nutrients.
In addition, rainwater doesn't contain chlorine, fluoride and other salts that have been added to tap water.
These added chemicals affect the soil flora which have an effect on soil fertility.
Nearly any homeowner can collect rainwater, since the roof and gutters do most of the work.
Furthermore, they can harvest huge volumes. An inch of rain, falling on a 2,000-square-foot roof, produces 1,200 gallons of runoff, which is enough to supply a family of four for about two weeks.
Plants prefer it, especially if tap water has been treated with softening salts, which dampen plant growth.
The lack of minerals in rainwater make it more effective for washing hair or doing the dishes.
Furthermore, reducing or eliminating mineral deposits in pipes and water heaters can extend their life, requiring less maintenance and associated costs.
Using rainwater has obvious budgetary benefits, but there are reasons to do it besides putting a dent in the water bill.
With countries around the world anticipating water shortages within the next five years, this may become an attractive option for many
In some places, collecting rainwater is a crime.
Colorado and other western states in America have water rights dating back to the 1800s that give priority to decades-old properties for water access.
Under these restrictions, any captured rainwater is considered stolen from those who own the waterways into which that water would have flowed had it not been collected. Who would believe they would still allow such a moronic law to exist in an age where the lack of water for ever burgeoning populations is a constant threat
Resolution? Get as many water collectors (rain water tanks) around your home as you can, use them with soaker hoses, solar pumps etc. Build swales where you can hold the water for longer periods, allowing it to spread deeper across your land.
Don't waste a drop.....

Here's something to bring tears to your eyes, if I have my facts right
At the moment the Fitzroy River in Rockhampton is emptying out the equivalent of the Sydney Harbour every day. At least I hope it's every day and not every hour. There's no way it could be every hour.
a) what an incredible waste
b) it's going to do a huge amount of damage to the fisheries and coral reefs.
I won't even get into the run off from the coal mines.
I can't believe it's illegal to capture rainwater. That goes beyond moronic. But then again I'm waiting for the day we get a similar kind of law here or a tax on rainwater collection.
They certainly are doing it hard over there Nev, with some devestating results.
I hear youo on the tax, its a very probable position as the financial crisis spreads across the world, taxes from everything...
Years ago I heard the argument that rainwater tanks were bad for the environment because they stop the water going into it's natural waterways... what??? These days there is so much man-made crap everywhere, nothing is going anywhere naturally, and if it is, it is taking a heap of who-knows-what with it!
Anyways, I am listening to lovely sounds of rain falling at the moment, filling up our tank and wicking worm garden beds, and giving all those lovely nutrients to my garden. The rain is causing havoc in QLD, but it is still much needed down here.
I'm with you Dixie, a crazy statement! Wish we were getting some rain here, it is sooooooooooo dry!
I have heard the terms 'hard' & 'soft' water but though it was just some detergent product marketing mumbo jumbo. So thanks for the info.
Most welcome Jason, it was something a little new to me too!
I would love to talk to you about an issue that I feel is a hot topic in environmental news. I have written an article that I think your readers would be interested in seeing on your blog.
Did you know that in the last 100 years, our agricultural habits have left us with about a quarter of the crop diversity we once had?
Encouraging grocery shoppers to branch out from their usual selections and to join the local food movement, will help us conserve the forgotten species, and create a more sustainable agricultural system.
Kindly,

Hi Kori, you are welcome to send me your article. if it fits with the theme of the blog I am happy to utilise it, giving you full credit of course.
And yes, I am very aware of the loss of diversity in crops and in fact have a few posts dedicated to that, type in monsanto and seeds etc into my search bar and you will see the posts.
I agree with you, encouraging heritage, non-gm seed planting, talking to family & friends and local businesses is important:)
Water is precious, despite the amount that has fallen here in the last few weeks.
Tanks were discouraged here after mosquitos became a serious problem in the 70s. They only became 'popular' and encouraged again once our dams began to drop to less than 10%, along with the almost non-exsistant rainfall.
Nothing is sweeter than free, clean rain water from the sky!
Hi LFIC, I agree, without our water we are not a viable species. Mossies here are not a problem if the tank is sealed with the correct netting. In addition I know many who use a bottle of olive oil on the surface of the water, the mossies cannot breed then, and of course the oil floats so never mixes with what comes out the bottom of the tank:)
