Bill Butterworth talking about water
25 May 15
Water will become increasingly important in world politics and power; at least as important as hydrocarbon fuels but in a different way. Water is necessary to produce food. Estimates of the proportion of global water use by agriculture vary between 70 and 85 % while total water use is going up and available water is (mainly due to pollution) going down. The use of mineral fertilisers, especially Nitrogen fertilisers, is causing pollution of ground water. We have a problem and Houston has an answer. There are ways of eliminating that pollution of ground water by mineral fertilisers and making irrigation water go 10 times further – at least.
To avoid pollution of groundwater, switch from soluble mineral fertilisers to organic-based technology. It is possible to stop the pollution from mineral fertiliser by adding it to a compost operation based on organic wastes. It is possible to make irrigation water go much, much further by building what are called “top soil reservoirs” out of compost. Large amounts are needed and there is a great deal of suitable wastes produced in all human communities.
There is more detail on this in two books;
