Canadian farmers are concerned over the possibility of higher prices and less competition from the pending merger of Potash Corporation of Saskatchewan and Calgary-based Agrium Inc.
Update September 14, 2016: Now it looks like Monsanto agreed to sell itself to Bayer AG, in a $57 billion deal that would create a new agricultural mega-company.
This highlights the importance of diversifying farming methods. Aquaponics does not rely on the chemical fertilizers that comprise 25% of the input costs, or the herbicides and pesticides that comprise another 25% of traditional farming input costs.
The use of herbicides kill important microorganisms and leave soil lifeless. A recent study by the University of Colorado argues, "the erosion of soil fertility is masked by a 'soup of nutrients' poured over the crop lands, giving us a false sense of security."
