4.30 a.m. Time to hit the track . . . the day awaits.
Essential educational material for kids , IMHO. It's a shame the schools don't use it.
Easy to understand why that won't happen though :-
This is the same stage that the discussion reached four years ago in the Fact and Fantasy thread.
I don't think so ; which type of aquifer are you referring to? I didn't use the term.
Edit : I see what the Greens are saying about shallow aquifers, which is groundwater. Where I farm there is no risk to the main water sources which are artesian - sealed underground tanks under considerable pressure, and not subject to infiltration.
The groundwater which the Greens are talking about is not confined and finds its way into streams and rivers, swimmable or not. This is the water that should have been of concern , but the clean streams outcry got all the attention.
So the real cleanup , in respect of nitrate has yet to begin, and the economic consequences nationally are massive.
Rather the opposite : that the campaign to fence some waterways was largely window dressing to placate the urbanites. The nitrate was already present through percolation down through the soil profile , before the water even reached the stream. Some honest scientists pointed this out at the outset of the furore . Phosphorus remains largely an erosion problem in the hill country because phosphorus binds to the soil.
But I am suggesting that "swimmable" is not a scientific term and should not have ever entered the debate. That fact seems to have been realised now, and the focus should be on appropriate soil use, stocking rates , nitrogen fertiliser , and bought in feed .
Actually I can recall having exactly this conversation with Gary Taylor and Guy Salmon several years ago. There simply has to be less nitrogen going in the top of the soil profile for there to be less coming out the bottom.
What is in your 2040 link?
Some enlightenment there :-
""This is a problem we've had to deal with for many years... it's not marijuana that's the problem, it's really P, "
taking a dim view of humanity.
Not really. We the people have been intentionally duped into a condition resembling narcolepsy. We wake up slowly , and one at a time . . . . at first.
"it needs to be changed and soon."
Mother Nature will sort it out if we don't.
" Here, the challenge is that the concentrations of nitrates are quite low, so we need to be able to know that it can pick up those small amounts."
Shocking news this morning at 5 a.m.
Apparently the waters that Forest and Bird et al want most to be cleaned up , will never be "swimmable" because they are under the ground.
You wouldn't read about it.
And I see Joyless Mike still repeating his nonsense about the Manawatu River being one of the most polluted in the world. Apparently this idiot is a lecturer in Ecology at a university. That says quite a bit about the state of education in Godzone.
