ABSTRACT
Rapid expansion of the WestVirginiapoultry industry has
prompted questions concerning the effect of this expansion upon
water quality. This survey was conducted during October and
November of 1994 to determine the level of Best Management Practice
(BMP) implementation in order that educational and technical
programming could be targeted toward specific BMPs needing greater
attention. Using a set of 52 questions, poultry producers
demonstrated their management of poultry litter and mortality and
how they were making agronomic decisions on their farms. Improved
methods of poultry litter storage, application, and distribution
are occurring. Poultry mortality management has made a dramatic
shift to composting as a low-cost solution. Agronomic management
is an area that needs targeted programming to demonstrate to
producers how they can maximize poultry litter as a fertilizer.
Overall, the producers are showing a commitment to voluntary land
stewardship that will ensure continued, environmentally sound
growth of the poultry industry in the Potomac Valley.

INTRODUCTION
The five WestVirginia counties, Grant, Hampshire, Hardy,
Mineral, and Pendleton historically have had poultryproduction as
a part of their agricultural makeup. During the last five years
this industry has undergone considerable expansion within the
Potomac River Watershed, becoming the primary agricultural
enterprise in the State.
The rapid expansion of the poultry industry combined with West
Virginia's established beef cattle industry has generated questions
about the effects of the large number of animals on water quality
in this watershed. State and Federal Agricultural Agencies
including Natural Recourse Conservation Agency, Consolidated Farm
Service, State Soil Conservation Agency, WestVirginia University,
WVU Extension Service and the WestVirginia Department of
Agriculture have joined together to address these concerns through
educational and technical programs. This collaboration has evolved
into the Potomac Headwaters Project.
To determine the best utilization of agency personnel, a needs
assessment is underway. A component of that assessment was the
completion of a survey of poultry producers to determine specific
sizes of operations, management of litter, types of equipment
utilized, and specific agronomic decisions. The poultry
integrators agreed to distribute and collect the survey from each
1
of their producers. This was done during the fall of 1994.
Because of the industry cooperation, 53% (199 respondents) of the
surveys sent out were returned by producers. A 53% return is
commonly an acceptable number for this type of study. Therefore,
the conclusions should allow agricultural producers, the poultry
industry, and State and Federal Agencies to use this study as a
planning tool to ensure the continued growth of all agricultural
activity while maintaining and improving water quality in the five
county area.
PURPOSE OF STUDY
The purposes of this study were threefold. First, to
determine the degree of implementation of water quality improvement
practices by the poultry producers in the Potomac River Watershed.
Second, utilize the responses to this questionnaire to target
technical and educational programming on specific management
practices. Finally, to demonstrate the successes which are already
occurring through voluntary adoption by producers.

METHODS AND MATERIALS
A 52 question survey was initiated during the summer of 1994
in the Potomac Inter-Agency Water Quality Office (See Appendix A
for questionnaire form). The document was reviewed by district
conservationists, county agents, university specialists, and
poultry integrators. During October and November the questionnaire
was distributed to 375 poultry producers in the five county
2
poultry producing area, collected by the integrators upon
completion, and returned to the Water Quality Office. A database
was prepared and all returned surveys were entered into it.
CMR Research Associates were contracted to statistically
analyze the results. Included in this report are frequency
distributions for each questionnaire item. Included in Appendix B
are 65 tables presenting the responses to the 52 questions within
the survey.
The results are presented in bar graph format to clarify and
condense the number of tables presented by CMR Research Associates.
A 90% confidence interval was used for all questions. The number
of responses to individual questions vary because of non-response
error. On the bottom left side of each bar graph is a percentage
response from total number of poultry producers in the Potomac
Watershed and the actual number of responses.
A short follow up survey is contained in Appendix C. This was
conducted in September 1995 with 90% of producers responding to the
questionnaire.
RESULTS AND DISCUSSION
Section I. Type of Production and Geographic Location
Q1. What type birds do you raise?
All producers that returned surveys responded to this
question. The breakdown of bird types shows that in the sample
approximately 48% of producers raise broilers, 27% raise layers,
11% raise pullets and 15% produce turkeys (Figure 1).
Q2. How many tons of litter do you produce annually?
Figure 2 shows that 10% of poultry farmers produce 0-100 tons
per year, 53% or the majority produce 101-400 tons, 13% produce
401-600, 13% produce 601-800 tons, and 10% produce over 800 tons of
litter per year.

Q3. How many houses do you operate?
Figure 3 shows a distribution of the number of houses per
operation. The average number of houses per producer is 3 [90%
CI{± 0.21}].
Q4. In what watershed is your operation located?
Figure 4 shows that the largest concentration of producers
(34%) is located in the largest watershed, the South Branch (see
Appendix D). The second largest concentration (13%) is in a much
smaller watershed, the Lost River area.
The significance of the distribution by bird type is the large
number of broiler producers that have 6 to 7 flocks per year and a
corresponding accumulation of litter to store or apply at each
cleanout. The other bird types have one or two cleanouts per year
with reduced accumulation of litter.
The 53% of producers that accumulate 101-400 tons/year of
litter have a manageable amount that can be stored in a shed or
under a tarp without difficulty. The 27% of producers accumulating
401-800 tons/year have a greater challenge storing, applying and/or
selling this quantity of litter.
Seventy-seven percent of producers have from 1 to 3 houses.
Operations of this size should allow a producer flexibility in
litter utilization through storage, application and/or selling of
the product. Producers with 6 or more houses account for 9% of
total producers. These operations should have large treatable
acreage available, large storage facilities and/or written plans to
facilitate distribution of the litter to other agricultural
producers.
Lost River watershed has limited treatable acreage for the
large animal numbers located in the valley, making redistribution
of litter to other areas a high priority (Appendix D). The Water
Quality Incentive Program (WQIP) funded by USDA in 1994 has been
implemented and is designed to encourage improved management of
livestock manure and poultry litter within the Lost River
watershed. In Grant County, the Mill Creek watershed also has a
large number of producers in relation to the treatable acreage.
Section II. Size and Type of Farm Operations
Q5. How many acres do you normally operate?
Figure 5 shows the distribution of farm sizes. The largest
group consists of farms which operate less than 50 acres at 28%,
followed by 51-100 acres at 13%, 101-250 acres at 22%, 251-500
acres at 21% and over 500 acres at 16%.
Q6. Is your farm mainly grassland/hay, row crops, timber or other?
Figure 6 shows that 84% of the farm land is grassland/hay.
