| MAIN ISSUES |
Increasing Dairy and Swine Manure Safety, Value and
Utilization Through Bioaugmentation |
| Industrialized agriculture has increasingly concentrated swine and dairy operations into larger units, which has created agronomic, environmental, social and custom hauler issues. |
| AGRONOMIC ISSUES: |
|
- Application volume, heavy application equipment and soil compaction.
- Manure is generally high in salts if not biologically digested.
- The flexibility, to-date, to use manure as starter or foliar fertilizer has not been an option.
- Escalating energy and commercial fertilizer expenses.
- A more economical plant nutrient source is needed.
|
|
| ENVIRONMENTAL ISSUES: |
- Odor around dairy facilities and during application.
- Contamination concern of surface and ground water with phosphate and other manure nutrients.
- Excessive fly populations around dairy facilities.
- Concern about food contamination grown with manure containing antibiotics or drugs.
|
|
| SOCIAL ISSUES: |
- People and communities envision concentrated dairy facilities as a detriment due to odor (air pollution) and ground water contamination, which has created a negative image of the industry to the public.
- Concerns for workers’ health issues when exposed to short and long term manure odors.
|
|
|
|
CUSTOM APPLICATOR ISSUES: |
- Overall ease of handling and applying liquid manure.
- Cost of extracting manure from the pit and handling solids.
- Safety issue regarding lethal gas during the pumping process.
- Odor complaints during hauling and application.
- Surface and ground water contamination liability concerns.
- Ability to achieve uniformity from start to finish when pumping a pit or lagoon.
