The soil burning thing is a standard school experiment. I'm sure anyone doing it a higher levels would haver no issues with their students doing it.
||Possibly less spectacular than the thermite process that we did at school. I didn't see the programme, but of course some soil won't burn and some will. Fortunately our wood is on the former, but remember a fire that went on for weeks a couple of miles down the road from here when the soil caught fire and I was only 4 at the time, so quite spectacular.|
I like the thermite process. I had a hole in the ceiling of my last place from it.
The actual soil in the ground catching fire is a bit scary really.
i took a while to watch it right through but it was quite interesting.
the stuff about slowing run off and erosion surprised me as i thought that contour farming was normal and that gaps of grass would be a first thought for folk on slopes.
ps mr chinn's asparagus and broccoli is rather nice and im glad his farm isnt in the river even if it did take a few years to organise keeping his soil.
||Great. That's my viewing this evening sorted|
Got to watch this at last. I would give it 7 out of 10. Pretty informative and a reminder of just how precious the stuff is.
Could do without the repetitive shots of him driving his landrover though and showing the same clips of closeups of his booted feet as he walks (its just not sexy).
