Today I received an interesting email from Chuck Cunningham, a tree grower in Buellton, CA who has taken a keen interest in the work I am doing. He writes:
I forgot to mention an unusual occurrence in my “fruitless” olive trees. I have been tending and growing some 40-50 Olea Europae “low fruiting” olives that for the last several years have only developed perhaps 6 olives grand total. After using Azomite on the trees they are all fruiting? I am not sure if they will hold, but it is interesting since to my knowledge nothing else has changed.
Over the years I’ve seen a number of cases where stressed, poorly-producing olive trees have responded nicely to topical treatments with soil minerals. I am aware of several olive growers who are improving their yields significantly by amending soils with alkaline-rich minerals, which improve soil fertility and, thus, tree health and productivity. The soil minerals that I use in my practice are a combination of finely-ground Azomite and calcitic limestone. Azomite is a volcanic ash that is loaded in trace minerals. The calcitic limestone helps to buffer soil acidity and provide calcium, a major constituent of bark and wood.
