JIT Learning Modules
Using a series of seven modules, producers will learn how to manage on-farm composting of animal mortalities.
While it is recommended that producers complete the modules in order, some might skip to modules addressing their specific needs.
Carcass composting law in California is evolving. This module teaches producers how to stay in compliance with the new regulations.
An effective carcass composting pile supplies oxygen and water to microbes that break down carcass tissue. This module teaches how a compost pile works, helps you understand how things can go wrong, and how to fix struggling piles.
Selecting a good site helps avoid operational and regulatory problems. This module explains how to choose the best location for the composting site.
Compost piles that struggle or fail, most often do because of inadequate air, water or nutrient composition. This module explains how to construct piles that don’t have those problems.
Just like we monitor crop and heifer growth, we need to monitor compost pile activity as well. This module shows you how to monitor for temperatures, leachate, odors, flies, scavengers and other problems.

Just because a pile is struggling doesn’t mean you have to pull it apart and start from scratch. This module teaches you how to troubleshoot common problems with compost piles.
Quality finished compost is a valuable soil amendment. This module describes how it can be land-applied while remaining in compliance with local and state regulations.
Learning Objectives
When learners have completed this training they will be able to:
- Describe how composting works, in general, to break down organic waste.
- Explain the purpose and benefits of composting animal carcases on the farm.
- Explain the potential risks and hazards associated with composting animal carcases.
- Explain the rules and regulations around composting animal carcases in California.
- Explain what permits for both air and water protection may be needed.
- Select a composting site.
- Build effective composting piles or windrows.
- Monitor a composting site.
- Deconstruct the site when composting is complete.
- Explain troubleshooting solutions to common concerns when composting.
Assessments
The JIT training includes online quizzes and assessments to help learners confirm they have understood and can apply key steps in on-farm carcass composting. These quick checks ensure farmers and employees can confidently implement best practices.
