Farmable Soil I

Soil is being lost at a rate of 3-12 pounds per pound of food grown due to the farming practices (both chemical and organic) currently being used.1

6 inches of topsoil are needed to grow food crops, and 24 inches are needed to grow the best crops most efficiently.

On a world average, nature requires 500 years to build 1 inch of topsoil.

With GROW BIOINTENSIVE, it is possible to build up to 20 pounds of soil per pound of food eaten2 annually, up to 60 times faster than in nature3.


Footnotes:

1) Soil is being lost at a rate of:

  • 6 pounds of soil for every pound of food grown using U.S. mechanized chemical agriculture.
  • 3-5 pounds of soil for every pound of food grown using U.S. mechanized organic agriculture.
  • 12 pounds of soil for every pound of food grown in developing countries, where 90% of the world's people live.
