One of the crucial factors in improving the nutritional value of our food is to get the crops we grow to function in the field at optimum rates. One of the ways this can be achieved is by the application of trace elements in the right configuration for those crops in their situation. The one size fits all approach does not work. By testing we have to tools to determine quite accurately what the needs of a given crop in a given location are. If we respond correctly then that crop will function at an optimal level in the field. The resulting harvest will then also give food that will meet our criteria for good and balanced nutrition. Over the past forty years I have done many tests which invariably prove that to be the case.
