Today\’s interesting little example:
Perhaps the most surprising tip about growing quality grass in 2011 is that fields may need the added nutrient of sulphur, since winter fallout from the burning of sulphurous coal is no longer available.
It\’s perhaps not a very important trade off, or we could regard it as one that we\’re entirely happy to make.
That the skies are not clouded over with coal dust (both from the urban banning of the use of low grade coal and the installation of electrostatic precipitators at power stations) is good, that the farmers now might have to spread sulphur on the fields is bad.
As I say, it\’s a trade off we\’re entirely happy to make, but it is a trade off all the same.
