Enviromental Management at Smithfield’s Hog Production Division Missouri

Smithfield’s Hog Production Division of Missouri is committed to and takes seriously its responsibility for protecting the environment and promoting environmental stewardship. This philosophy starts with our senior management and extends to every employee. We will enhance our leadership position in environmental management and demonstrate our ongoing commitment to manage our businesses in accordance with the following principles:

  • Strive to comply with the letter and spirit of environmental laws and regulations.
  • Implement practices where feasible to prevent pollution, conserve natural resources and reduce and beneficially reuse waste.
  • Pursue continual improvement in environmental performance through our environmental management system.


Sustainable Environmental Management System

At Smithfield’s Hog Production Division of Missouri, we demonstrate our environmental commitment every day in all areas of our operation. Smithfield’s Hog Production Division of Missouri has developed a Sustainable Environmental Management System that utilizes sound environmental principles to ensure proper usage of nutrients generated in animal waste.

Smithfield’s Hog Production Division of Missouri’s nutrient management program is designed as a “sustainable cycle” to safely use the nutrient-rich organic fertilizer.

There are five components of the sustainable cycle: nutrient management, waste management, lagoon management, irrigation management and crop management.

We monitor and evaluate the entire system, always looking for opportunities to improve.


Nutrient Management

The management process begins with diet formulation. We make a conscious effort to understand the nutritional needs of the pigs we raise. Our goal is to maximize lean gain by creating a diet that makes the most efficient use of Total Digestible Nutrients (TDN). By maximizing the efficiency of each diet, we can substantially reduce the amount of animal waste generated.

  • We create unique diets to meet the individual needs of each pig at each stage of development. A typical diet is a blend of corn, soybean meal and  wheat midds, with a balance of organic minerals and vitamins to meet nutritional demands.
  • Once the feed is created at the mill, it is transported to the production location. Our feed delivery system is also based on nutritional need.
  • This customized feeding process maximizes the efficient use of Total Digestible Nutrients, and minimizes both wasted feed and animal waste.


Manure Management

The goal of the manure management phase is to effectively utilize the effluent as rich, high-quality organic fertilizer.

  • Soil samples are taken and these samples are analyzed and results are used to plan crop nutrient needs.
  • In-stream water monitoring is conducted to verify that the waters of the state are not being polluted.
  • Lagoon water is tested to measure the nutrient content. Soil under irrigation is tested twice each year and each crop is tested.


Irrigation Management

Smithfield’s Hog Production Division of Missouri maintains an extensive irrigation management program to ensure appropriate irrigation procedures are utilized at all times.

  • Each winter, our analysts review soil and lagoon analysis data to help determine crop nutrient uptake and removal. This enables us to plan for the amount of nutrients to be utilized for the upcoming planting season.
  • We have developed new equipment such as tool bar irrigation and expanded the use of center pivots to help phase-out the use of traveling-gun equipment for irrigation. This will help reduce any application odor and allow for more even distribution.
  • Extensive monitoring of storm water run-off and lakes is done each year.
  • We irrigate onto ground containing a crop that will later be harvested. The irrigant carries valuable nitrogen, potassium and phosphorus, which penetrate the ground and are used by the plants to enhance growth.
  • Smithfield’s Hog Production Division of Missouri follows strict irrigation guidelines to prevent run-off. Our irrigation crews constantly monitor lines and equipment.
  • A “work-order” is issued by our Environmental Health and Safety (EHS) Department to each irrigation crew. This work-order details the information needed to properly irrigate an area. Each work order contains strict guidelines from not only us, but the Missouri Department of Natural Resources (DNR) and the University of Missouri.


Crop Management

Crop management involves planting, harvesting and marketing the crops grown on land owned and irrigated by Smithfield’s Hog Production Division of Missouri. We have replanted several acres of our ground with grasses – primarily Orchard and Timothy. These grasses reduce erosion, stabilize top soil and provide good nutrient uptake. The hay is then harvested and sold as a source of feed for north Missouri cattle producers.

  • With the development of waste system technologies like the ones at our Whitetail and Homan Farms, a reduction in the amount of nutrients in irrigation effluent will be realized. This will lead to more application of effluent to choice locations, reducing the amount of acres irrigated annually.
  • Enhanced mapping and tracking capabilities are now being used to allow clearer pictures and maps of areas for land application.


Lagoon Management

Lagoon management is a process involving inspection, monitoring and sampling. The Missouri DNR checks our data quarterly and annually.

Lagoon integrity inspections are done on a timeline:

  • Twice daily
  • Once monthly
  • Quarterly by DNR
  • Semi-annually by EHS and Land Nutrient Management (LNM) Department supervisors

Lagoon level monitoring is accomplished by lagoon levels being taken and reviewed weekly.

Lagoons are sampled:

  • Annually for nitrogen, phosphorus and potassium
  • Once per year to sample sludge volumes and run analysis

These five components: nutrient management, manure management, lagoon management, irrigation management and crop management, complete Smithfield’s Hog Production Division of Missouri’s Sustainable Environmental Management System.

This system converts organic waste into a valued resource and demonstrates Smithfield’s Hog Production Division of Missouri’s commitment to environmental leadership in the pork industry.


Irrigation Update

Farms with a check mark indicate irrigation may take place at that farm this week. This list is updated weekly.


Environmental Management System

We employ an Environmental Management System as part of Smithfield’s Hog Production Division of Missouri’s Environmental Policy.


What is an Environmental Management System?

  • It is a method to achieve and demonstrate sound environmental performance by controlling the impact of our activities on the environment.
  • To be effective it needs to operate within the overall structure of the organization.
  • It depends upon the commitment from all levels, especially top management.
  • It is built upon and its effectiveness is measured against the organization’s Environmental Policy..
  • It works by continually going through the process of Planning→Implementing→Checking→Reviewing→Planning

What does it mean to Smithfield’s Hog Production Division of Missouri?

  • We have identified the significant ways our farms can affect the environment.
  • We have identified priorities and set appropriate environmental objectives and targets to improve the ways we impact the environment.
  • We are establishing a structure and system to help us meet those objectives and targets.
  • It will enable Smithfield’s Hog Production Division of Missouri to facilitate planning, control, monitoring, corrective action, auditing and review activities to ensure that our Environmental Policy is within compliance.
  • The net effect is to continually improve Smithfield’s Hog Production Division of Missouri’s environmental performance.
