What is Conservation Agriculture?
Permanent Cover - Cropping Systems for
Sustainable Agriculture, based on three
principles:
Minimum soil disturbance = No-tilage
Permanent soil cover
Diversified crop rotations
(FAO, 2001)
What is No-tillage?
No-tillage is defined as a system of
seeding crops into untilled soil by
opening a narrow slot, trench or band
only of sufficient width and depth to
obtain proper seed coverage. No other
soil tillage is done.
