It's nice to see the newly renamed BOP Regional Council pretending to be interested in fixing soil erosion on farms.
Previously as Environmental BOP they struggled to control erosion and pollution. According to the Niwa's 2009 report, after 20 years of environmental agencies pollution and erosion had increased! Quick, change the name!
This erosiion will never stop while chemical fertilisers are allowed to be spread on and around our environment and our farm land.
Super phosphate is the combination of Rock phosphate blended witth sulphuric acid, a toxic mix!
Rock phosphates are so high in undepleted uranium that several mines are on offer as uranium deposits. Morocco is the largest exporter and its phosphate is on that list.
Rock phosphate also contains the heavy metals lead (Pb), Arsenic (As), Mercury (Hg), Cadmium (Cd), and Fluorine (F) and there is an enhancement of these toxic metals when blended with sulphuric acid, the additive that results in Super Phosphate. These heavy metals are all accumulating in our soils and transferring through to our waters and our food. (abridged)
