Abstract Glancey,
J., J.T. Sims and D. Snyder. 2007. Agronomic and environmental implications
of sidedressed poultry manure as a nitrogen source for crops. JEMREST
3:206-221. DOI:
10.4029/2007jemrest3no121 A prototype applicator for
sidedressing row crops with solid waste materials, such poultry litter, was
developed and field tested. As configured, the applicator can meter and
deliver animal manures and other raw solid wastes between rows of a growing
crop without the material contacting the crop. Results from a three-year
field study clearly indicate that new poultry litter management strategies,
using this sidedressing equipment and improved soil and plant nitrogen tests,
should improve the agronomic and environmental efficiency of corn production
in the mid-Atlantic region. Economically optimum yields were obtained with
starter fertilizers and moderate sidedress N rates, and poultry litter as a
sidedress material was found to be as effective as UAN. The results of our
study make it clear that new poultry litter management strategies, using
improved N tests and field application technology, should improve the agronomic
and environmental efficiency of corn production in Email info@jemrest.org for full text |
