Each row in the vineyard has its own irrigation line and each line has a cap and valve at the end. Working at either end of the rows, Vinomaker and I flushed water through each of the lines to clear out anything that may have accumulated in the lines since the vines were last watered in October of last year. (Also, every emitter along the irrigation lines are checked for blockages and replaced if necessary.) And because we are on a well in Vinoland, the accumulation-culprit is always ferrous iron. Well, the water in the lines was ferrous (completely dissolved) when it went in, but, as you can see in the photograph, it comes out as ferric (no longer dissolved). Hello, oxidation.
Making up about 5% of the earth’s crust, iron is one of the earth’s most common elements. Although present even in city/tap water, iron is seldom found at concentrations greater than 10 mg/l. As little as 0.3 mg/l can cause water to turn a rusty colour. But it's a great colour.
The Pinot grigio vines didn't care about the colour of the water, they just enjoyed their long, cool drink.

Gosh! I didn't realise growing vines was so complicated!
I was going to ask whether using stainless steel piping would help,
but then read that the minerals were actually in the water from
the well.
You do seem to work very hard in 'Vinoland', do you ever get the
chance to take a vacation? I do hope so!
Just put some more stuff about our beloved city on my blog,
best wishes,

Tango!
I'm guessing you're too busy for a movie, but you are beginning to remind me of Glenn Close in Skylark
That little 'skylark is showing-up everywhere! ;)
Oh, the irony of it all...
Trubes: It's not that bad. And besides, it's fun.
Great coverage of all the Cunard festivities on your blog. Looking forward to being home.
Thud: I liked Tango. Does look like it a bit.
NHW: Have not even heard of that film.
Tomasso: Titter, titter.
