A large portion of unused crop residues is burnt in the
fields primarily to clear the left-over straw and stub bles after the combine harvest. Studies have reported
several ill effects of crop-residue burning on soil orga nic carbon and fertility, including reduction in produc tivity in the long term, environmental pollution and
human health. It also produces greenhouse gases causing
global warming. Rice and wheat produce large amounts
of residue in India. Non-availability of labour, the high
cost of residue removal from the field and the increasing
use of combines in harvesting the crops are the main
reasons for burning crop residues in the fields. Rice
straw is unsuitable animal feed due to its high silica con tent and wheat straw for due to its hard stem and diffi culty chewing in unchopped form. Using supplements
like urea and is feeding straw sprayed with urea impro ves its nutritive value and intake. We have developed a
mechanized baler equipped with a urea spraying system
for spraying urea during baling operations on crop resi dues (paddy or wheat straw) to enhance their nutritional
value. The developed system was evaluated in combine
a harvested wheat residue field and nutritional analysis
was performed. The crude protein in untreated wheat
straw increased from 3.68% to 10.10% after urea
treatment. The metabolizable energy was also found
to improve by 3% compared to untreated straw. Thus,
urea-treated bales have potential use in dairy farming.
