reducing the cost of fossil fuel and the
associated carbon emissions to the
atmosphere.
• Reduces the loss of pesticides and other
applied chemicals. This is because higher
infi ltration rates with more surface resi-
due results in less runoff moisture-holding
capacity due to higher soil organic matter
that results in less leaching.

(vii) Disadvantages
• Adoption of reduced tillage in humid,
cool soils would primarily affect the dis-
tribution of SOC in the profi le, unless
carbon inputs were increased (Lal et al.
1998b ).
• Specialized, expensive equipment is
required or much hand labor in the case
of very small-scale growers.
