So i asked Gabe the question directly here is his reply:
Brown's Ranch Brian, Great question. The answer lies in the
miracle of a properly functioning mineral cycle. This occurs
when we have a healthy ecosystem. By this I mean we have the
combination of soil biology along with root exudates from a very
diverse plant community and very diverse insect and animal
communities all working to insure a properly functioning mineral
cycle. We have shown that this mineral cycle is actually taking
organic forms of these nutrients and converting them to
inorganic (plant available) forms. Tests done on our soils by
Dr. Rick Haney, ARS Temple, Texas have proven this. Now, it is
true that when we export produce from our land we are exporting
nutrients however, there is no way for me to know how much of
these nutrients occur in the soils on our ranch.
For you see, a proper functioning mineral cycle is able to cycle
organic minerals that are for example, in the case of
phosphorus, currently "tied up" as rock phosphate. We have not
used any synthetic fertilizers on our home unit since 2008 and
yet current tests show that nutrient levels in the top 24" are
increasing despite our "exporting" grains and meat. Our soils
are alive, our management just needs to allow it to function
properly.
