10:00 - 10:50 am Soil Health Benefits of Manure Application and Manure Nutrient Balancing Tool

William Pan

Dr Tao

- Dr. William Pan and Dr. Haiying Tao, Washington State University

Land application of dairy manure provides numerous benefits to crop growth and soil health. It provides not only macronutrients such as nitrogen, phosphorus, and potassium, but also micronutrients particularly boron, sulfur, and zinc. In addition, the impacts of manure applications can last many years via buildup of soil organic matter. However, applying manure on crop land in a sustainable manner can be a challenge for many dairy operations. This discussion will cover balancing the path of manure nutrients from efficiently land-applied manure into soils and plants while minimizing nutrient losses to air and water.


A model (Manure Nutrient Balancer), for using manure, soil and crop information to making manure application rate decisions was developed in the early 1990’s by Hermanson et al. The principles of this decision support tool will be described, and related to a current model developed by Brad Joern at Purdue University that has integrated these principles while adding nutrient loss vulnerability assessments of animal farming systems.

10:50 - 12:20 pm Comprehensive Nutrient Management Planning for Washington Livestock Producers
- Dr. Brad Joern, Purdue University

Field-specific manure application rate and time vary with manure nutrients content, soil nutrient status, soil type, slop of the field, distance of a field from water body, weather forecast, etc. However, proper manure allocations is time consuming, complicated and beyond many dairy farmers ability. This discussion will cover the importance of soils, fields, crops, storage structures, weather and regulatory issues during development of a Comprehensive Nutrient Management Plan.

The Manure Management Planner (MMP) software will also be demonstrated. MMP is a Windows-based computer program developed at Purdue University that's used to create nutrient management plans for crop and animal feeding operations. MMP helps the user allocate manure (where, when and how much) on a monthly basis for the length of the plan of 1-10 years. This allocation process helps determine if the current operation has sufficient crop acreage, seasonal land availability, manure storage capacity, and application equipment to manage the manure produced in an environmentally responsible manner. MMP is also useful for identifying changes that may be needed for a non-sustainable operation to become sustainable, and determine what changes may be needed to keep an operation sustainable if the operation expands. MMP currently supports 45 states, including WA, in compliance with state Extension and/or NRCS guidelines.

12:20 - 1:00 pm LUNCH
   
1:00 - 1:50 pm Alternative Use of Dairy Manure

Andy Barry, pHd

- Andy Bary, Senior Scientific Assistant, Washington State University

Excess land application of manure can pollute water bodies by increasing the chances of losing nitrogen and phosphorus from crop land. The excess manure should be exported from dairy farms. However, it is costly to export raw manure because of its high water content and low nutrients content. This presentation will discuss strategies for dispose excessive manure nutrients, such as composing and anaerobic digestion.

1:50 - 2:40 pm Use of an Application Risk Management System

Nicole Embertson

- Dr. Nichole Embertson, Whatcom Conservation District

The Whatcom Conservation District in Washington State has developed a progressive Application Risk Management (ARM) System that complements Nutrient Management Planning by providing site specific and real-time decision making tools targeting the transport of manure via runoff and leaching. These include a real-time, automated Manure Spreading Advisory which provides a three day risk rating for runoff based on precipitation forecast; an easy to use, web-based ARM Worksheet for farmers to evaluate manure application runoff risk on a specific field and day; and support tools including a website (www.wadairyplan.org), dynamic manure application setback distances, and field level risk mapping. Using these tools, producers are able to utilize manure more effectively with a high level of stewardship while significantly reducing their potential for a runoff or leaching event.

10:00 - 10:50 am Manure Nutrient Balancer - Decision Making Tool for Land Application of Manure

William Pan

Dr Tao

- Dr. William Pan and Dr. Haiying Tao, Washington State University

Estimating amount of manure produced, amount of manure can be applied on crop land in an agronomic and environment friendly manner is the first step in the proper manure handling and utilization. Amount of manure produced by confined dairies can be estimated based on well-established knowledge. Field-specific manure application rate and time vary with manure nutrients content, soil nutrient status, soil type, slop of the field, distance of a field from water body, weather forecast, etc. However, proper manure handling is complicated and beyond many dairy farmers ability. This topic will introduce The Manure Nutrient Balance tool, is a user-friendly on-line decision-making tool developed by WSU. Its purpose is to calculate the optimum manure application rate to balance nutrients with crop needs while protecting quality of surface and ground water. The model has two basic components that estimate manure nutrients production and agronomic rates of manure application for crop production.

11:00 - 11:50 pm Comprehensive Nutrient Management Planning for Washington Livestock Producers
- Dr. Brad Joern, Purdue University

Manure can be valuable source of nutrients for crop production and soil health improvement. However, applying manure on crop land in a sustainable manner can be a challenge for many dairy operations. This discussion will cover the importance of soils, fields crops, storage structures, weather and regulatory issues during development of a Comprehensive Nutrient Management Plan.

1:00 - 1:50 pm Agronomic and Environmental Principles of Land Application of Manure

Andy Barry, pHd

- Andy Bary, Senior Scientific Assistant, Washington State University

A nutrient management plan is designed to help farmers to apply nutrients for maximum agronomic values and minimum risk of nutrient loss. It provides field-specific short-term and long-term nutrient management plans, farm nutrient balance, and strategies for dispose excessive manure nutrients. This topic will focus on (1) the essential basics in nutrient management planning. (2) Alternative use of excess manure.
