Depending on the scale you work at, it takes work to get away from
grasses, and grasses may dominate over time under neglect... then mowing
or grazing the grass becomes the alternative to letting the grass grow
and become more competative... but then mowing/grazing can be a
disturbance that encourages grasses which are well adapted to that kind
of distrubance -- you're in a feedback cycle. In some settings, fruit
yield is limited by soil moisture, and so reducing transpiring leaf area
in association with your trees could be a strategy to increase monocrop
yield. Not saying its a good idea, or the best solution -- just is what
it is and can pay the bills if you happen to be brainwashed into
thinking about bills ;) So Fukuoka has good ideas for converting to
non-grass plants, but it looks risky from the perspective of someone
conditioned to like the control of mowed grass, and transition to a
semi-wild system may in fact be risky for yield as you figure out what
the hell your doing.
