'Low-Input' a First Step to Permanent Cropping


TropSoils scientists have devel-
oped a low-input cropping system
that could help farmers progress from
shifting cultivation to permanent ag-
riculture on acid soils in the humid
tropics.
Shifting cultivation has been
blamed for much of the deforestation
in the humid tropics. Scietitists esti-
mate that each acre of permanent,
well-managed cropland could save
five acres of tropical rainforest per
year.
The low-input cropping system
includes a kudzu fallow, a rotation of


acid-tolerant rice and cowpea culti-
vars, crop-residue return, chemical
control of weeds and pests, and the
use of small amounts of fertilizers and
lime.
While low-input cropping is con-
sidered transitory, an experimental
low-input system at Yurimaguas,
Peru has remained productive much
longer than expected. Seven continu-
ous crops in three years have yielded
a total of 13.8 tons per hectare of rice
and cowpea grain, with no applica-
tion of lime or fertilizer.
