leguminous plants have rhizobium
bacteria in their root nodules.
they convert atmospheric nitrogen
into soluble nitrogen compounds
which can be used by plants.
so farmers grow leguminous
plants between two main crops
to enrich the soil
with nitrogen and to reduce the
use of chemical fertilizers.
It is also called multiple cropping
soybean, cowpea, green beans,
pigeon pea.
