Agricultural Waste Management - Ching Dairy Innovative Practice Field Day
Ted Tyson, Professor and Extension Engineer in Biosystems Engineering, recently participated
in a Juniper Creek Clean Water Partnership Field Day held on the Ching Dairy in
Mobile County.
Auburn University and the Alabama Cooperative Extension System is one of the
twelve Juniper Creek Clean Water Partners involved in the project.
The field day highlighted an innovative method of separating dairy manure solids
from milking parlor waste before the waste enters the waste treatment lagoon.
The method, which uses a large geotextile bag, has proven successful in lagoon
renovation operations where lagoon solids are separated from lagoon contents and
later land applied using "dry" manure land application equipment.
This installation, separating manure solids before entering the lagoon, may be
the first of it's kind in the US. The aim is to reduce lagoon volatile solids
loading, thus improving treatment efficiency and greatly diminishing the already
low odor from a properly sized treatment lagoon. Handling the solids as "dry"
manure will also allow normal wastewater irrigation to be the primary lagoon-level
control operation needed.
Geotextile bag work at the Ching Dairy is part of Tyson's larger applied research
program dealing with geotextile bags and other methods of manure and wastewater
handling to help address animal waste management challenges faced by Alabama's
dairy, swine, and poultry farmers.
