Project Name: |
Animal Waste Management Program in Hawaii: Implementation
and Evaluation of the Modified Deep Litter System Under a Tropical
Agricultural Ecosystem |
Start/End Date: |
October 1994 to October 1997 |
Contractor: |
Francis Pacheco
Hawaii Association of Conservation Districts

Hilo, HI 96720
Phone: (808) 935-0992 |
Background/
Overview: |
In traditional animal waste management programs, the animal
pens are washed down with water. The effluent is then contained
in a lagoon which becomes a potential source of contamination to
our surface waters and groundwater. These effluent lagoons are
nearing capacity and have resulted in environmental violations
due to effluent discharge into streams. |
Objectives/Goals: |
To install, demonstrate, and evaluate the effectiveness of the
modified deep litter system in reducing the nonpoint source pollution
problem commonly associated with confined swine operations and
to evaluate the effectiveness of various non-commercial and commercial
carbon sources used in the modified deep litter system to transform
green waste and animal waste problems into high value compost resources. |
Methods Employed: |
• Public education and information through field demonstration
days, farm tours, presentations at statewide meetings
• Data on raw materials, compost, animal performance |
Watershed: |
South Point, island of Hawaii
|
Size of Project: |
Kealia Farms, a Naalehu farm along the Kona coast
in Kealia and Naalehu towns, island of Hawaii |
Deliverables: |
• Fact sheet
• Slide show
• News articles
• Exhibit for displaying at fairs |
