Lesson 2: Materials and inputsOverview
Producers new to organic production frequently have questions about allowable materials. The NOP Standards do not explicitly list all materials permitted for use in organic systems. Instead they provide general guidelines as well as specific prohibitions for certain types of inputs, such as genetically modified organisms.
In earlier sections of this course, we've talked in passing about various organic inputs and emphasized that the Standards require an integrated approach to fertility and pest management issues. As an organic farmer, you should try to avoid an "input substitution" mind-set toward transitioning. You're also generally better off keeping the use of purchased inputs to a minimum. But the use of some organic inputs can be essential to commercial viability.
In this lesson we'll review the rules governing input use, list some commonly used materials and caution you about some common materials pitfalls to avoid.
By the end of this lesson you should:
• Understand what the National List is and how it regulates the use of synthetic and natural materials
• Recognize commonly used fertility and pest management inputs
• Understand organic regulations regarding the use of composts and manures
• Be able to list the three types of "categorically prohibited" inputs under the NOP Standards
