1992 Earth Summit Report* indicate that the mineral content of the world's farm and range land soil has decreased dramatically.
Percentage of Mineral Depletion From Soil During The Past 100 Years, By Continent:
North America 85% ** South America 76% Asia 76% Africa 74% Europe 72% Australia 55%
** Some US farms are 100% depleted and some are 60% depleted, the average is 85% depletion as compared to 100 years ago. This is worse than in any other country in the world because of the extended use of fertilizers and "maximum yield" mass farming methods
