Agricultural Practices

Introduction

Agriculture is a dominant land use in the Cayuga Lake watershed. As reported in the Preliminary Watershed Characterization Report, approximately one-third of the direct drainage is in active agricultural production. Dairy farming is a major industry; about 57% of the agricultural lands in the watershed are dedicated to livestock and products, and 42% are in field crop production. The largest dairy farms are located in Cayuga County. As measured in sales, field crop production is concentrated in Seneca and Cayuga Counties.

Agriculture is an important economic and land use partner in the watershed. The highly valued open space and beautiful vistas in the watershed are a direct result of agriculture shaping the landscape. However, county census data reveal that a diminishing percentage of the work force is directly involved in agricultural production. This decrease reflects the dramatic trend away from the small farm and towards increased size and mechanization of farming operations. At the same time, increasing numbers of watershed residents are choosing to live outside of the more densely populated areas, resulting in rural residents who are unfamiliar with the realities of farming operations and less tolerant of inevitable odors or inconvenience.

The economic and technological trends promoting larger farming operations can increase the challenges associated with careful management of soil and water resources. Even the most environmentally conscious producers are faced with handling an excess of nitrogen and phosphorus; that is, more nutrients enter from feed, fertilizers and (for nitrogen) legume fixation than leave via milk, meat, or crops. The excess increases with the number of cows per acre.

The primary pollutants of concern in the Watershed are nutrients (phosphorus and nitrogen), sediment, pathogens, organic material, and pesticides. As discussed in the Preliminary Watershed Characterization, and the Chapter II, these substances may originate from many sources including residential lands and urban stormwater. Nutrients, sediment, pathogens, organic material, and pesticides can migrate from agricultural lands to surface and ground water through processes including surface runoff, erosion, infiltration, and aerial drift.

Monitoring data confirm that agricultural pollutants reach the surface waters (both the tributary streams and the lake) and groundwater of the Watershed. Phosphorus and sediment can degrade the quality of surface water resources. Nitrate-nitrogen, due to its high solubility, is a contaminant of special concern in groundwater. Monitoring data confirm the loss of pesticides to streams and their presence in lake waters. Left unchecked, migration of nutrients, sediment, pathogens, organic material, and pesticides threatens the long-term health of the lake and watershed.

Goals

Existing Measures

Soil conservation and land stewardship are important values of the watershed’s agricultural community. A network of technical assistance and financial support for agriculture has been in place for decades. Agencies including County Soil and Water Conservation Districts, the Natural Resources Conservation Service of the U.S. Department of Agriculture, the Farm Services Agency, Cornell Cooperative Extension, and others actively promote measures to reduce the potential adverse impacts of agriculture on the environment. For the most part, producers have adopted measures that are protective of Cayuga Lake and the watershed. Many of these measures are voluntary, although state and federal regulation of farming practices has increased in recent years. Some important programs are listed below, with examples of how they are implemented in the watershed.

Recommendations

Number 4 Recommendations Related Issue(s) Potential Responsible Organization(s) Measure/ Target Approximate Cost
A Through the framework of the Agricultural Environmental Management (AEM)   program, implement whole farm planning (the focus is on individual producers). Critical issues such as water quality and habitat protection within the farm’s watershed are central considerations in identifying pollutants and protective measures. Practices are selected based on site-specific conditions of soil type, topography, drainage, cropping practices, and livestock density.
The four most critical issues in this watershed in need of Best Management Practices (BMP) are: nutrient management, erosion control, manure management, and herbicide application.
A1 All farms in the Cayuga Lake watershed should develop a Comprehensive Nutrient Management Plan (CNMP) (exit this site) that meets the provisions of NRCS/New York State Standard 312 (see NYS Standard 312 in Adobe Acrobat format). The Comprehensive Nutrient Management Plan should include specific recommendations tailored to individual producers and the conditions of soil type, drainage, cropping practices, and livestock density. (See also: Conservation Practice Standard Waste Management System, NRCS, in Adobe Acrobat format) A, SR, DW, WQ, N, P SWCD, NRCS, LO, CCE 100% of livestock operations by 2008 based on federal regulation $15/acre without soil testing
The overall objective of the CNMP is to balance the nutrients entering and leaving the farm. In order to reduce phosphorus losses from agriculture, off-farm inputs of phosphorus in feed and fertilizer should be balanced with outputs in products such as milk, meat, and crops. Soils should be managed to retain nutrient resources for crops.  Specific elements of the NMP may include the following (NYS Standard 590):
A1a
  • Promote nutritional management as a tool to optimize feed efficiency and ultimately reduce nutrient content of animal waste. Nutrient management (590) cost sharing may be available through EQIP or Ag Nonpoint Source programs
A, SR, DW, WQ, N, P SWCD, NRCS, LO, CCE 100% of livestock operations by 2008 based on federal regulation $25,000
A1b
  • Test soils and crops to define fertilization rate and timing
A, SR, DW, WQ, F, N, P SWCD, NRCS, LO, CCE $10/field/sample

$0.50/acre

A1c
  • Use the phosphorus (available phosphorus) index (currently in final approval stages for application to New York State watersheds) to determine the rate of manure application to specific fields.
A, SR, DW, WQ, N, P SWCD, NRCS, LO, CCE
A1d
  • Plant small grain cover crops in regions with high leaching potential where nutrients need to be controlled.
A, SR, DW, WQ, F, N, P, S SWCD, NRCS, LO $30 to $50/acre
Many of the larger dairy farms in the Cayuga Watershed have begun to develop CNMP that meet the NRCS/New York State Standard 312 (in Adobe Acobat format) as part of the permit requirements for the CAFO program. The CAFO regulations, which currently apply to larger livestock operations, provide a framework for developing and implementing parcel-specific recommendations for cultivation, cropping, and manure spreading practices designed to minimize environmental impact. Under the current implementation timetable, farms with animal herds of all sizes will be subject to the CAFO regulations by 2008.
The recommendation to develop Comprehensive Nutrient Management Plans extends to crop farms as well.
