Cooperative Extension System
The Cooperative Extension System (CES) is a public-funded, nonformal, educational
system that links the education and research resources and activities of the U.S.
Department of Agriculture (USDA), land-grant universities and 3,150 county
administrative units. As its stated mission, the Cooperative Extension System
helps people improve their lives through an educational process that uses
scientific knowledge focused on issues and needs. To accomplish its mission,
Cooperative Extension sets program priorities based on the needs of the people it
serves. As people's needs and priorities change, program priorities must
change too.
The Idaho Cooperative Extension System has over 140 faculty strategically located
throughout the state, including 84 agricultural agents and home economists
stationed in 42 of 44 counties. In addition, faculty (specialists) are located on
campus in Moscow and at research and extension centers in Aberdeen, Caldwell,
Idaho Falls, Kimberley, Parma, Sandpoint, Tetonia and Twin Falls.
Water Quality Survey
Water is the lifeblood of Idaho, and water quality is an important part of
Extension's effort in our state. Our traditional industries --
agriculture, forestry and mining -- are all water-dependent. Even a
large portion of tourist revenues in Idaho is tied to attractions with
water. We must protect water quality to maintain our high standard of
living and uniquely rich quality of life in Idaho.
Extension has a tradition of working in areas that affect water quality. For
instance, CES employees provide accurate fertilizer recommendations,
pesticide information and irrigation management recommendations based on the
latest research. These have a positive impact on water quality.
Extension faculty were surveyed in 1990 to document programming areas related to
water quality and to quantify the amount of time expended in water quality
related efforts.
Survey Results
In 1990, University of Idaho Extension faculty devoted over 6,000 employee days
to programming in water quality-related issues. Some of this time was redirected
from other areas. Water quality programming efforts were placed into 6
categories.
- Crop Management (57.0% of effort)
- Livestock/Range Management (16.1%)
- House and Garden Chemicals (7.7%)
- Youth Programs (7.2%)
- Domestic Water (6.0%)
- Forestry (6.0%)
Water Quality Effort Distribution

Extension's programming efforts within each of these six categories are
explained on the following pages.
Crop Management
Crop management practices in Idaho have a significant effect on water quality.
The University of Idaho is working to develop farming practices that are both
economically and environmentally sound. In 1990, 57% of extension's water
quality effort was devoted to crop management. Most of the effort dealt with
fertilizer, pesticide and irrigation management recommendations. The 1990
survey documented over 3,400 employee working days devoted to aspects of crop
management impacting water quality. The following programs affect water
quality:
- Provide accurate pesticide recommendations that protect water quality (1,143
days/year)
- Provide fertilizer recommendations for Idaho crops to maximize nutrient use
efficiency, optimize economic yields and protect water quality (681
days/year)
- Provide irrigation management recommendations that maximize crop water use
efficiencies, conserve water and minimize erosion and leaching of agricultural
chemicals into groundwater (573 days/year)
- Provide information about erosion control to protect water quality from
sediment and associated contaminants (287 days/year)
- Provide economic assessment of crop management strategies to protect water
quality (186 days/year)
- Provide crop rotation information to use residual soil nutrients more
efficiently (174 days/year)
- Provide training on pesticide storage, handling and application and disposal
of pesticide containers (142 days/year)
- Provide information and training about integrated pest management systems
that improve pest control and result in reduced pesticide use (110
days/year)
Livestock/Range Management
Water quality issues that affect livestock also affect the general public.
Extension is working with ranchers and range managers to increase animal
productivity and protect water quality. In 1990, the University of Idaho
Cooperative Extension System spent 970 employee days working with water issues
affecting livestock and range management. Specific programs included:
- Provide information on grazing and riparian management to increase the
productivity of the system and also reduce soil erosion and protect water
quality (448 days/year)
- Provide economic assessment of management practices that protect water
quality (160 days/year)
- Provide information on current methods of livestock pest control that are
both economically sound and environmentally responsible (153 days/year)
- Provide information on dairy waste management that maintains water quality
(123 days/year)
- Provide information on how to maintain and protect water sources for
livestock (92 days/year)
Forestry
Extension promotes forestry practices that are both economically and environmentally sound. In 1990, 360 employee days were devoted to water quality aspects of forestry and woodlot management. specific programming areas include:
- Provide information on sustainable forest production based on soil and water quality (146 days/year)
- Provide information on timber management programs that consider water quality (138 days/year)
- Provide information on erosion control and road building that will minimize soil loss and stream sedimentation (36 days/year)
Youth
Extension places an emphasis on youth programming. Several extension youth
programs target natural resource education. In many cases, these programs deal
with water quality issues. Extension also works with teachers on natural resource
educational efforts. Over 430 employee days were spent in 1990 on natural
resource programming for Idaho youth. Youth programming for water quality issues
includes:
- 4-H youth natural resource programs (192 days/year)
- Natural resource camps that include water education programs (136
days/year)
- Direct contact with classroom teachers for development of natural resource
curricula (38 days/year)
- Classroom education (34 days/year)
- FFA and FHA programs (24 days/year)
Domestic/Urban
Extension designs water quality programs as needed for urban and domestic target
audiences. Projects range from laundry detergent recommendations to the safe
disposal of household chemicals. In addition, information on water treatment,
local sources of water and factors affecting water quality are regularly
provided. In 1990, extension devoted 360 employee working days to domestic/urban
water quality issues. Specific programs included:
- Provide recommendations on laundry detergents that protect water quality (85
days/year)
- Provide water sampling to determine water quality on a local basis (50
days/year)
- Provide information on water storage and treatment (49 days/year)
- Provide information on adverse health effects of poor water quality (42
days/year)
- Provide information on how to evaluate water sources (41 days/year)
- Provide information on disposal of waste water (33 days/year)
- Provide information on proper disposal of hazardous waste (30 days/year)
- Provide economic assessments of water use and associated treatment (15
days/year)
House/Lawn/Garden Chemicals
House, lawn, and garden chemicals can have a significant and large impact on
water quality. Extension provides information and materials that relate proper
storage, handling and application techniques of household chemicals. Extension
also provides information on lawn and garden chemicals. In 1990, the University
of Idaho Cooperative Extension System spent 465 employee days providing education
on using household, lawn and garden chemicals.
Cooperation with Other Agencies
Extension shares its water quality expertise with other federal, state and local
agencies operating in Idaho. Recent interagency water quality programs and
projects include:
- Series of workshops targeted at managing pesticides wisely were conducted
across the state in early 1991 in cooperation with the Soil Conservation Service,
Soil Conservation Commission, Idaho Division of Environmental Quality and U.S.
Environmental Protection Agency.
- Federally funded Demonstration Water Quality project in Cassia and Minidoka
counties directed at implementing nutrient, pesticide and irrigation best
management practices (BMP's) in agricultural systems. Joint project with the Soil
Conservation Service and Agricultural Stabilization and Conservation
Service.
- Federally funded hydrologic unit project in Canyon, Gem, Payette and
Washington counties to assess impacts of agricultural practices on groundwater
quality. Joint project with the Soil Conservation Service and Agricultural
Stabilization and Conservation Service.
- Idaho Farm Bureau well testing program, a cooperative effort between the
Idaho Farm Bureau, UI Cooperative Extension System, UI Agricultural
Experiment Station, Division of Environmental Quality, Soil Conservation
Service and Soil Conservation Districts.
