Post-harvest grazing can remove 80%, or as much residue as burning, when the stocking density and grazing duration are adequate. Seed yield in post-harvest graze treatments were comparable to those in the full-load burn treatment, indicating post-harvest grazing is a potential non-thermal alternative for managing Kentucky bluegrass residue and sustaining seed production. About 43% fewer cattle are required with the bale-then-graze treatment compared to the full-load graze treatment. Switching to baling as a method of residue removal will require most farmers to purchase a baler and stacking equipment or have the residue custom harvested. A producer would need to harvest over 1,800 A before it would be profitable to purchase haying equipment versus having it custom harvested.
Project objectives:div style="margin-left:1em;">
Develop livestock grazing systems and/or use of emerging biotechnology alternatives that optimize biomass turnover and maintain or increase bluegrass seed yield without burning.
Compare nutrient cycling efficiency in burned, mechanically managed and grazed bluegrass systems.
Investigate above ground insect pest and predator relationships in each bluegrass production system. Monitor diseases and weeds associated with the different treatments.
Examine the economic efficiency of each bluegrass production system including the associated production, price, and financial risk.
Identify potential key socio-cultural and economic costs and benefits of livestock grazing management practices or biotechnology alternatives versus current open-burning practices.
Disseminate information to growers, field consultants, extension educators, and scientific audiences.
