When you hold the answer to both the nitrogen and the carbon issue you cannot but smile while reading all the crap that surrounds both.

Nitrogen is an essential requirement for plants, although they only need 1.5 per cent.
Availability is no problem; 33,000 tonnes per hectare is in the Earth's atmosphere. It can be freeloaded out of the atmosphere by plants, nitrifying bacteria, mycoryzal fungi and potentised in worm castings, supplying all the nitrogen you need ‘free', as it has been for millions of years.
Enter urea containing 46 per cent artificial nitrogen (remember the plant requirement is only 1.5 per cent). It is manufactured by the chemical fertiliser industry, connected to the oil and gas industry. There is a diminishing supply at increasing prices but it is devastating to the soil biology, the soil carbon content and our environment. Why not get it free?
Carbon is an essential requirement for plants, but they need 45 per cent.
Availability is plentiful. According to the United Nations there is an overload of carbon dioxide in our atmosphere and this desperately needs to be reduced (global warming).
The best sequesterer of carbon dioxide is pasture. Yes, pasture. However, it must be noted that artificial chemical fertilisers deplete carbon in the soil. So, to gain carbon credits and keep your pasture pumping, apply a good rock dust based ‘live' fertiliser and I know where you can get one.
