At least 30% of the soil surface should be covered (at the time of planting) for proper soil conservation and
to enhance soil quality.
nal inputs such as herbicides and
fertilizers can still be applied, but
should be done in ways and quantities that do not hinder soil biological processes. However, reduced
tillage, maintaining an organic soil
cover and crop rotation should be
followed and limits specified by the
FAO should not be exceeded. CA
should enhance biodiversity and
natural biological processes above
and below the ground surface,
which should in turn lead to improved yields and a profitable farming systems.
