This subject is from an article from 2010, but it highlights how successful any commercial farming, landscaping, golf
course or any other large grand scale agricultural related operation can successfully eliminate all synthetic chemical inputs. The real beauty here is that when 10s of 1000s of Euros or Dollars can be saved, more and more employees can be hired to care for commercial agricultural system maintenance which ultimately not only provides jobs for the jobless, but ecological health for the planet. Of course it could put many agro-chemical companies out of business, but I doubt anyone will shed a tear.
