Hi Stephen There is a method called Brix testing that a farmer can do himself. It uses a refractometer to measure suger levels in plants and fruit. When suger levels get above a certain level for each group of plants then you have reached a balanced soil energy level. A figure between 9-15 is my understanding. This is also subject that i would like to study this coming year. It is one of the means which Dan Skow uses in his book Mainline farming for the 21st Century to get his soil nutrient levels to balance and you can do it your self. Cheers Tony Robinson
