Monahan, Nutrient Management Summer Fellow Dr. Thomas Parsons, Assistant Professor of Swine Production Medicine Center For Animal Health And Productivity New Bolton Center School Of Veterinary Medicine University of Pennsylvania Efficient nutrient management requires swine producers to evalu ate every aspect of their farm, including animal nutrition, crop ping and manure handling. By co ordinating these phases of the pro duction system, nutrients can be NATIONAL LIVESTOCK SHOW CODE OF CONDUCT (PART 4 OF 5) OVERSIGHT Never ruin an apology with an excuse. Editor’s Note: Part four in this series describes the proce dures and guidelines for oversight of the proposed National Livestock Show Code of Conduct in local events and responsi bilities and composition of the oversight committee. As the steering committee for the Pennsylvania Code of Ethics Prog ram for Animal Exhibitions plans to implement a uniform set of guidelines for events specifically in Pennsylvania, it is important for participants to understand some of the local, regional, and especially national guidelines that will influence the final guidelines for Pennsylvania. The original, unedited initial document will be provided in this series of articles. Responsible comment is invited and welcome. Adapted from the Introduction for the National Livestock Show Ring Code of Ethics (Conduct) Entry Forms: May it be known to all participants, parents, instructors, agents, contributors, judges, officials, associations, affiliate organiza tions and other interested parties, that, by wholehearted agree ment and unanimous consent, the Livestock Shows represented by their endorsement of this document do hereby bond together in unconditional support of the attached document entitled: “National Livestock Show Code of Conduct” Participation in this agreement is available to any Livestock Show who has signed this document and meets the following requirements: The Livestock Show must provide a copy of “National Lives tock Code of Conduct” either published with the show criteria or as an official supplement to the information listing rules and reg ulations listing the competition available for entry. This will be the official notification to exhibitors of the shows’ intent to parti cipate in this agreement. By making entry in this livestock show or event, you are verify ing you have read “The National Livestock Show Code of Con duct” and understand the consequences of and penalties involved for illegal, unethical, inhumane, and unfair practices of competi tion. You also verify that you may be prohibited from future parti cipation in organized fairs and livestock shows in the United States, and could face possible criminal prosecution and/or civil penalties if implicated in any of the aforementioned acts. Jgoltoo utilized and recycled more effi ciently. Recently we discussed the theory behind nutrient manage ment and began looking at se lected best management practices for increasing nutrient utilization and recycling in the nutrition and animal feeding phase of the nutri ent cycle. This third part of the series on nutrient management will focus on cropping strategies and best management practices for manure handling in order to com plete the nutrient cycle. The aim of cropping phase of the cycle, similar to the objective for nutrition and animal feeding, is to meet the nutrient requirements of the plants for optimum yields with as little excess nutrients as Kimberly Johnson possible. Two strategies can be employed to accomplish this task. You can match the available nutrients in the manure and fertilizer to the de sired crop or match the crops to the nutrients available in the man ure. For either of these strategies, you need to know the nutrient re quirements of the particular crop and the available nutrients in the soil and the manure. Soil and manure testing are an essential step in accurately deter mining your available nutrients. Soil tests are valuable tools for in dicating which field needs nutri ents are present in your manure. Although book values for the nu trients concentrations in swine manure arc available, these nutri- SEE ONE OF THESE DEALERS FOR A DEMONSTRATION: ADAMSTOWN CARROLL’S DEER CREEK EQUIPMENT, INC.

Once you know your available nutrients through the manure and soil testing, calibrating your man ure spreader will enable you to ap ply the manure at a rate which meets the crops’ needs and avoids over application of nutrients. Our preliminary research demonstrates that nearly three fourths of the Pennsylvania swine producers questioned neither test manure or calibrate their spread ers. Overapplication of nutrients does not benefit the crops and can potentially cause surface and ground water contamination and hence nutrient loss to the environ- Route 235 Dameron, MD 301-872-5553 CLUGSTON AG & TURF, INC.

To further prevent the loss of nutrients to the environment, con servation methods which mini mize soil and nutrient runoff should be included in your crop, ping practices. The use of grass field borders, grass waterways, contour planting, reduced tillage, conservation tillage, terraces, and filter strips reduce the movement of phosphorus or potassium into surface water. Phosphorus and po tassium are tightly bound to the soil and move when the soil is eroded. Your manure handling strate gies are the final step that we are going to discuss in coordinating your operation with the nutrient cycle.
