How much mm of water would a heavy dew leave on grass?
A decent crop will catch and hold more waterI've been pondering this myself with cropping over the last 6 dry weeks.
I would guess the longer the grass / crop / leaf area, then the more dew will condense on it and run down the stem ?
Ergo, dew mm depends on size of crop. 10" well tillered wheat gets a fair bit, bare soil / recently sown spring crops get sweet FA.
But it will also have a greater surface area to transpire water back to the atmosphere....A decent crop will catch and hold more water
Possibly but a short open crop wouldn’t catch and hold it in the first place to loose itBut it will also have a greater surface area to transpire water back to the atmosphere....
I'd agree, and so would our cat.Just pondering really as i cut grass yesterday ?and it had 2mm overnight in the gauge
In the field the last 1 I got to cut theres hardly moisture left on the standing grass but the mown grass has a few droplets on,I'm not worried the tedder will sort it out.
Just got me thinking that I could have seen it as wet with 2mm on as a heavy dew falling
Bit disappointed to see you feed your cat Pete - I thought you NZ guys left your livestock to forage for themselves with no supplementary concentratesI'd agree, and so would our cat.
She's been out mousing in the grass behind the barn this morning and came in looking pretty wet, just from dewy grass. View attachment 875613
We catch a lot of dew and keeping the soil surface moisture constant is no.2 priority behind infiltrating heavy rain events.
She needs it, unlike her fat-ass carpet-shark colleague Fox. He's close to 7kg at 2 years old.Bit disappointed to see you feed your cat Pete - I thought you NZ guys left your livestock to forage for themselves with no supplementary concentrates
