OHS System Components
    Below - Dense root cluster under dripper in South African OHS grove.  The management goal is to provide non-limiting
    conditions to these root clusters to achieve maximum growth when trees are young, and high fruit production during
    bearing years.  Plant growth management is enhanced, allowing influence of flowering and other growth events.
