Field Technology & Water Quality Outreach

Proceedings Home | W2W Home waste to worth 2017 logo

Purpose

In 2015, Washington State Department of Agriculture (WSDA) partnered with local and state agencies to help identify potential sources of fecal coliform bacteria that were impacting shellfish beds in northwest Washington.  WSDA and Pollution Identification and Correction (PIC) program partners began collecting ambient, as well as rain-driven, source identification water samples.…

Recommendations for Manure Injection and Incorporation Technologies for Phase 6 Chesapeake Bay Watershed Model


Proceedings Home W2W Home w2w17 logo

Purpose

A Best Management Practice (BMP) Expert Panel was convened under guidance of the Chesapeake Bay Program’s (CBP) Water Quality Goal Implementation Team to assess and quantify Nitrogen and Phosphorus load reductions for use in the Phase 6 Chesapeake Bay Watershed Model when manure is injected or incorporated into agricultural lands within the watershed.…

Developing Science-Based Estimates of Best Management Practice Effectiveness for the Phase 6 Chesapeake Bay Watershed Model

Proceedings Home W2W Home w2w17 logo

Purpose

The Chesapeake Bay Program (CBP) is a regional partnership that leads and directs Chesapeake Bay restoration and protection. The CBP uses a suite of modeling and planning tools to estimate nutrient (nitrogen and phosphorus) and sediment loads contributed to the Bay from its watershed, and guide restoration efforts.…

Water Quality Regulations and Animal Agriculture Curriculum Materials

As livestock and poultry production has intensified it is no surprise that regulations have become a more prominent part of the business. This module introduces the Clean Water Act (CWA) and it application to animal agriculture. This material was developed for use in beginning farmer and extension programs, high school classrooms, and for self-study or professional continuing education.…

Identify and Synthesize Methods to Refine Phosphorus Indices from Three Regional Indexing Efforts

Purpose

This project was started to work with regional CIG projects to calibrate and harmonize Phosphorus Indices across the U.S., demonstrate their accuracy in identifying the magnitude and extent of phosphorus loss risk, and provide suggestions to refine or improve existing Indices. This research is important to provide consistency among state Phosphorus Indices and their subsequent recommendations.  …

Relationship between Surface Waters and Underlying Stream and Ditch Sediment in Selected Eagle Creek Tributaries


Why are stream and ditch sediment important to water quality?

Best management strategies implemented in most watersheds to reduce phosphorus (P) loads to surface waters have been successful, however, internal P loading within streams and ditches may still provide P to overlying water. Phosphorus retention and release by sediments is important for understanding sediment P status and buffering capacity and for determining the potential environmental fate of sediment bound P in flowing water systems.…

Factors Affecting Household Use of Organic Fertilizer

Purpose         

New uses of manure can be win-win opportunities for livestock and poultry farmers, new users, and the environment. While there is increasing interest by crop farmers in using manure as a source of nutrients, another potential market is households. This study was conducted to look at factors that affect stated use of organic fertilizer, in order to enable producers and professionals to market this product to homeowners.…
