Para ver esta informacion en espanol, haga clic en la bandera mexicana en la parte superior derecho de la pantalla.
All 2025 INMP (and TNA) reports were due on March 1st, 2026, and now considered past-due. All late 2025 INMP reports (due March 1st, 2026) must now be submitted directly through GeoTracker. Operators must contact the Regional Water Board (AgNOI@waterboards.ca.gov or (805) 549-3148) to request access to the 2025 report form(s). The submission options provided below ONLY apply to 2026 INMP reports, please do NOT use them for 2025 (or prior) INMP (or TNA) reporting.
Looking for TNA? TNA reporting has been discontinued as of 9/1/26 as our region has officially entered Groundwater Phase 3 for reporting requirements which means that ALL ranches need to submit INMP reports for their 2026 crops.
Failure to submit a required INMP report may result in enforcement action by the Central Coast Water Board, and/or loss of Third Party membership with Preservation, Inc. Water Board enforcement actions for failure to submit 2022 TNA reports have included fines of approximately $40,000 (link to Water Board press release).
The required “monitoring” period for INMP (Irrigation & Nutrient Management Plan) summary reporting under Ag Order 4.0 has begun for all ranches. All ranches must file the INMP summary report on the 2026 crop year, no later than March 1st of 2027.
Third Party members must use Preservation, Inc’s reporting tools to submit their INMP summary reports.
Failure to submit a required INMP report may result in enforcement action by the Central Coast Water Board, and/or loss of Third Party membership with Preservation, Inc.

Section I – Introduction & Checklist
You will need the following information in order to complete the INMP report. You can download this checklist here: INMP Reporting Materials Checklist
Puedes descargar esta lista de verificación aquí: Lista para INMP
- Preparer Name
- Preparer Company
- Preparer Email
- Preparer Phone Number
- Calendar year of INMP data being reported
- Ag Waiver (AW) number
- Global ID (AGL) number
- Ranch name
- Assessor Parcel Number(s) (APN’s) farmed
- The total number of acres that were farmed
- Total number of acres left fallow
- Whether or not the ranch is a greenhouse, nursery, or hydroponic operation
- All sources of irrigation water (i.e. well versus city versus recycled, etc.)
- The average nitrate concentration (in mg/L or ppm) of irrigation water applied
- The average nitrate concentration unit of irrigation water applied
- Crop(s) you are reporting
- Total crop acres for selected crop*
- Crop acres takes into account successions (i.e. if you have 10 acres and you did two successions of lettuce then you will report 20 acres)
- Total volume (in gallons) of irrigation water applied to the entire reported acreage during the reporting period
- Amount of Nitrogen present in soil as pounds of Nitrogen per crop acres (lbs/crop-acre)
- Amount of conventional (synthetic) fertilizers and other materials as TOTAL pounds of Nitrogen
- Amount of organic (non-synthetic) fertilizers and other materials as TOTAL pounds of Nitrogen as well as the carbon-to-nitrogen (C:N) ratio and crop acres
- Crop Evapotranspiration (Crop-ET) for each harvested crop (exceptions for nurseries/greenhouses)
- Pounds of Nitrogen in harvested crop material
- Pounds of Nitrogen sequestered in vines/woody plant material (if applicable)
- Pounds of Nitrogen scavenged by cover crops or high-Carbon amendments (if applicable)
Section II – Recordkeeping & Calculations
If you are not already closely tracking the types and amounts of fertilizers and irrigation water that you apply to each crop, and the amount of harvested crop material, then you will need to do a significant amount of record keeping before preparing your INMP report.
Once you have all of your fertilizer, irrigation, and harvest records in one place, you will need to convert this information into the total volume of water applied, and the total pounds of Nitrogen applied to and removed at harvest for each crop on each of your ranches for the year.
Here is a link to the Regional Water Board’s introductory video on INMP reporting. Information on recordkeeping begins at the 3:50 point in the video: https://www.youtube.com/watch?v=Y-w882JKz0w
The following records or calculations are needed to complete the INMP report. Where available, we have provided links to recordkeeping and/or calculator tools. Preservation, Inc.’s TNA/INMP Calculator Tool (v1.03) can help with your conversions, record keeping, and data reporting. While Preservation Inc.’s Online INMP/TNA Web Calculators are a webform style calculator that automatically calculates your values entries. Use of these tools is not required, but they may be helpful if you do not already have a system in place:
- Volume of irrigation water applied, in gallons. Ag Order 4.0 requires that this be measured (not estimated).
- Flow meters are the most common tool for measuring water application
- Unit conversions – if you know the acre-feet or inches applied, you can convert to gallons (link to conversion tool)
- If you did not measure the irrigation volume in 2023, you should estimate this information in order to complete the INMP report for 2023 crops. You should also prepare to measure irrigation water in 2024.
- Pounds of N in irrigation water
- Testing methods/options
- Converting between “Nitrate as N” and “Nitrate as NO3” (Link to Water Board conversion instructions, see pg. 21)
- Conversion to pounds of N (Link to N in Irrigation Water Calculation)
- Soil nitrogen content from soil test
- Recommendations and Guidelines for Soil N Testing
- Testing methods/options:
- Soil N Self-Test
- Common labs and their reporting units: Commercial Lab Soil N Test
- Converting lab test results into the required reporting units/format
- Pounds of N applied in fertilizer
- Recordkeeping for fertilizer
- Converting pounds of fertilizer to pounds of N applied (Link to Water Board conversion instructions, see pg. 21)
- Converting volume of fertilizer to pounds of N applied
- C:N ratio
- Finding this information
- Organic versus synthetic/conventional
- Pounds of Nitrogen in harvested crop material
- Crop Evapotranspiration* (Crop ET)
*There are two options to calculate ET:
A. For single crop applications –
-
- Click Link to ET calculator
- Select commodity from drop-down menu
- Select more specific crop type from secondary drop-down menu
- Enter or select from calendar the start and end dates for your crop
- Use map to zoom to your location and click on or near your field of interest (this will allow the calculator to use the nearest CIMIS Station for weather data)
B. For multiple crops and plantings – Preservation, Inc. ET Calculator
-
- Download the MS Excel file
- Read the Instructions tab to learn how to correctly populate the CropETc_Input tab
- Populate the CropETc_Input tab for all crops and plantings
- Submit the saved file through the online ET Calculator
– You will receive an email within 5-10 minutes containing an Excel file with the calculated ET output
– If any records do not have a calculated output, read the Notes tab for troubleshooting tips

The Preservation, Inc. Irrigation & Nutrient Management Plan (INMP) Reporting Spreadsheet Form
The information required in the Preservation, Inc. INMP report Spreadsheet Form (an MS Excel file) is identical to the information required by the GeoTracker INMP web-form and the INMP-EZ Form. The layout is different, to support rapid data entry for growers and service providers who:
- Need to report on large numbers of ranches and/or crops; AND
- Already have systems in place to calculate the final values required for the report
If you use the Preservation, Inc. INMP report Spreadsheet Template to file your report this year you can use that saved file as a starting point for next year’s report.
