By Bruce Darrell, from Fleeing Vesuvius. This paper describes practices for ensuring that we can continue to feed ourselves adequately, even after a collapse in energy supply. Very few soils have a perfect balance of minerals. As a result, their fertility is limited and the crops grown on them cannot provide all the nutrients people need. As people can get food from elsewhere at present, these local deficiencies do not matter too much. However, if the option of filling one’s plate from all over the world disappears, human health will likely decline unless the missing minerals are applied over the next few years.
