Your Organic System Plan (OSP): Building & Maintaining It

The Organic System Plan (OSP) is the foundational compliance document of organic certification. It is a written, site-specific description of your operation's practices, procedures, and materials that demonstrates — on paper — that every aspect of your operation meets NOP standards.

Legal basis (7 CFR § 205.201):

Every certified organic operation must develop and maintain an OSP that describes the practices and procedures to be performed and the materials to be used in each production or handling activity. Your certifier reviews and approves your OSP before initial certification and annually at renewal. The OSP is the document your inspector uses during your annual inspection to verify that what is happening on your farm matches what you documented.

What the OSP is:

• Your farm's organic management blueprint — a complete written description of how you farm organically

• The reference document for your annual inspection

• The record of all inputs you are approved to use

• A living document that must be updated whenever your operation changes

What the OSP is not:

• A theoretical or aspirational document — it must describe what you actually do, not what you hope to do

• A static document — it must be updated and re-approved annually

• A guarantee of certification — it is reviewed and accepted by your certifier, who makes the certification decision

The OSP and your records work together: the OSP describes what you plan to do; your activity records document what you actually did.

Under 7 CFR § 205.201, a complete OSP must describe the practices and procedures to be performed and the materials to be used in each production or handling activity. Specifically:

Farm Description:

• Operation name, operator name, and contact information

• Field maps showing all fields, field names/numbers, acreage, and organic status (certified, transitioning, non-organic)

• Description of all facilities: storage buildings, equipment sheds, processing areas

Crop Production Practices:

• Seed varieties planned for each crop, with organic/non-organic status and any seed search documentation

• Tillage and cultivation practices

• Crop rotation sequence for each field

• Cover crop species and management

Soil Fertility Management:

• Soil amendment and fertiliser inputs planned, with evidence of allowed status (certifier approval, OMRI listing)

• Manure and compost sources and application protocols

• Nutrient management approach

Pest, Disease & Weed Management:

• All pest, disease, and weed management practices in the NOP hierarchy order (prevention first)

• All pest management materials with certifier approval documentation

• Monitoring and threshold protocols

Natural Resource Conservation:

• Practices for maintaining or improving soil, water, wetlands, and wildlife — NOP § 205.200 requirements

• Buffer zone descriptions and management

Record-Keeping System:

• Description of how you maintain and organize required records

• Where records are stored and how they can be retrieved

Contamination Prevention (for split operations):

• Practices for preventing commingling and prohibited substance contact

Developing your first OSP can feel daunting — but approached systematically, it is simply the task of documenting what you already do and plan to do. Here is how to approach it:

Step 1 — Start with your certifier's application materials:

Your chosen certifier will provide an OSP template or application form that structures the required sections. This is your scaffold — fill it in rather than building from a blank page. Different certifiers have different formats; use yours.

Step 2 — Walk your farm and document what you see:

Create a field map. Walk each field and record its history: what has been grown there, what inputs have been applied, and when. This field history documentation is the foundation of your land transition claim.

Step 3 — Inventory your inputs:

List every input you plan to use or may use in the coming season: seeds, fertilizers, pest management materials, equipment cleaning products. For each, note its source and confirm its compliance status.

Step 4 — Document your management practices:

Write down your crop rotation plan, cover crop plan, tillage approach, pest scouting protocol, and soil amendment program. Be specific — 'I rotate corn-soybeans-oats' is better than 'I use crop rotation.'

Step 5 — Describe your record-keeping system:

Explain how you will maintain and organize your records. Reference the specific tools you use.

Step 6 — Review with your certifier before submitting:

Many certifiers offer a pre-application review or can answer questions about what level of detail is expected. Use this resource — it reduces back-and-forth during review.

Your OSP must be updated at minimum once per year — as part of your annual certification renewal — and more frequently when your operation changes. Understanding what triggers a required update is essential for maintaining compliance throughout the year.

Annual update (required for every renewal):

• Review and update all sections to reflect the current year's planned activities

• Update field maps if any fields have been added, removed, or changed status

• Update the input list to add any new inputs and remove any no longer used

• Update the crop rotation plan to reflect the coming season's plan

• Confirm any commercial availability documentation for non-organic seed is current for the new season

Mid-year updates (required when anything changes):

• Adding a new field to your certified operation

• Adding a new crop not previously covered by your certification

• Using a new input not already on your approved list

• Changing a management practice in a way that materially differs from your current OSP description

• Changes to your record-keeping system or storage

• Adding or removing employees who perform certified activities

NOP's rule is clear: your OSP must accurately describe what you are actually doing, at all times. An OSP that describes last year's practices while you've changed your approach is a compliance risk — the divergence between OSP and practice is exactly what inspectors are trained to identify.

OSP errors are among the most common findings during organic inspections — and most are preventable. The ACA has documented the following as the highest-frequency OSP compliance issues:

1. OSP doesn't match actual practice:

The single most serious OSP error. Your OSP says you use variety X, but you planted variety Y. Your OSP describes one rotation but you made a different decision mid-season without updating. The OSP is only valuable if it accurately reflects reality.

2. Inputs on your shelves that aren't on your OSP:

During inspection, any input found in your storage that is not on your approved OSP input list is an automatic flag. Before every inspection, walk your input storage and confirm every product on the shelf appears on your approved list.

3. Outdated field maps:

Adding, removing, or changing the status of fields without updating your OSP and field maps creates confusion during inspection and raises questions about what else may have changed without documentation.

4. Vague or generic descriptions:

OSP sections that use generic language ('we use IPM practices' or 'we compost our manure') without specific descriptions of what those practices actually involve are difficult for certifiers to evaluate. Specificity builds certifier confidence.

5. Missing buffer zone documentation:

For farms with adjacent conventional operations, the absence of documented buffer zones and contamination prevention measures is a consistent inspection gap.

6. No description of the record-keeping system:

Your OSP must describe how records are maintained. 'Records are kept in a binder in the barn' is technically compliant; 'Records are maintained in Quick Organics' Digital Filing Cabinet, accessible by field and date' demonstrates a robust, auditable system.
