Being on city water, even when barrels run out it still gives me a place to gass off water (getting the chlorinie out takes about twenty four hours of sitting)...

Still some of all that rain left in there, but I am getting stingy. Everyone gets a good water tomorrow morning B4 work, corn got a good shot today, rows yesterday. Parts of the garden are looking a bit worn. Even the perfoliate compass plant looks a little wilty (and it must have a six foot tap root by now).

We need rain... global warming sucks...

anyone have any idea how long Nitrogen stays in rain water befor it evaporates??? I asked this question in the compost forum and didn't get an answer???? I have a 55 gal drum I keep full all the time, so was wonderin if it sits for awhile does it loose the Nitrogen out of it?

OK, chemistry is NOT my forte, so I might be missing something, but there's no N in H2O, so I don't see where the nitrogen comes in... how does that work? I HAVE heard that snow brings down atmospheric nitrogen trapped between the crystals.... :?:

Applestar Thanks for the reply! I thought rain water had nitrogen in it??? :? So what exactly is in rain water vs. well water? I always thought rain water had more N than regular well water, and I know for fact that rain water is better for plants than well water. What's the diff?? Pardon the ignorance! lol

I don't know why that would be true, unless the well had some sort of "contamination" (sulfur, chemicals, sewage, etc...).

I think the reason most people like to use rain water in the garden is because it's free [excluding the costs in materials to collect it], and it does not contain the chlorine that will be in most "city" water.

There's nothing wrong with well water as long as it's not treated or the underground water table isn't contaminated. With that being said well water is typically used for house hold things including drinking. The idea behind a rain barrel is 1. Not having to use water from a treatment plant that has chemicals in it. 2. it's FREE and 3. it's not depleting our clean drinkable water.

So if you have well water that you use for drinking then there the reason for using a rain barrel would be more related to #3 and possibly #2.

As far as the exact difference it's really hard to know. Rain water is fairly consistent but well water will have different minerals (like lime) and things in it from the ground (good and possibly bad). Same goes for water from a dehumidifier.

I have no idea, really. But here's a guess: Could it be that rainwater would have more dissolved OXYGEN in it? Raindrops could also bring down with them atmospheric particles that CONTAIN nitrogen.... :?:

... but couldn't the same thing be said of wellwater: i.e. via leached substances?
