Comprehensive Nutrient Management Plan
What is a CNMP?
A Comprehensive Nutrient Management Plan (CNMP) is a whole farm, progressive document. A CNMP contains records of the current activities on a livestock operation, an evaluation of the existing environmental risks, and proposals to reduce the risk of negative impacts to the environment. The objective is to ensure both farm production and environmental goals (clean water, clean air, and healthy soils) are achieved on the farm.
Why Should I Get a CNMP?
Having a CNMP developed for your farming operation provides you a strategy for managing your farm’s soils and nutrients. Having and following a CNMP may protect you from regulatory actions in case of an accidental manure spill or complaints about odors and other nuisances associated with the management and spreading of manure.
What Do I Need To Get Started?
You'll need to provide the following information listed below:
Field Information (Tract Number, Field ID, Acreage)
Soil Tests (Must be taken in the past 3 years)
Manure Tests (For Accurate Nutrient Values)
Manure Storage Information
Animal Information (Number of Head, Type of Bedding, etc.)
Type of Equipment Being Used on the Facility
To learn more about CNMP's, or if you have any questions please contact Taylor Gilmore, Nutrient Management Specialist, at the Wayne Soil and Water Conservation District at 330-263-5376 or visit our office for more details. We're located at 428 W. Liberty Street, Wooster, OH 44691, in the lower level of the building .
**The development of a CNMP may take several months.
There’s an App for Nutrient Management Record Keeping
Ohio Nutrient Management Record Keeper (ONMRK) is a computerized record keeping system that syncs with your smartphone or tablet to create a simple, easy, and quick way to record all of your fertilizer and manure applications from the field. The free app works on tablets, iPads, and smartphones. It can be downloaded from the Google Play Store for Android devices and App Store for Apple devices.
To get started, simply go to the app’s website www.onmrk.com. After setting up your account, enter your farm and field information. Download and open the app on you smartphone or tablet and enter your applicator key. All of the data that has been entered on your computer will now synchronize with your smartphone or tablet. The app features drop‐down menus and quick entry fields which make it fast and easy to enter the required information.
The application information you enter from the field is combined with the GPS Location data from your smartphone or tablet. Both the current weather data and the weather forecast for this location are recorded. Once the application is saved the data is synced with the website. From the website you can print your application records or export them to a spreadsheet.
The app was developed with input from OSU Extension Knox County, Ohio Farm Bureau, and Knox County Soil and Water Conservation District to meet the new state record keeping requirements for both Senate Bill 1 (SB 1) and Senate Bill 150 (SB 150).

New App Helps Farmers Know When to Spray or Spread
Published on October 22, 2018
COLUMBUS, Ohio — A new app from The Ohio State University will help farmers save both money and the environment.
The Field Application Resource Monitor (FARM) uses advanced weather forecasting to advise farmers on when to apply fertilizers and pesticides so that they aren’t washed away by rain.
According to Aaron Wilson, climate specialist for Ohio State’s College of Food, Agricultural, and Environmental Sciences (CFAES) and project manager of FARM, it is much more than just a fancy weather app.
“The app allows you to specify the location of your field in high resolution,” said Wilson. This means that the app can actually give specific forecasts for an area as small as 1.5 miles wide—allowing for incredibly accurate and detailed forecasts.
“It then provides guidance on the best time to apply fertilizers and manures based on the precipitation forecast” Wilson continued.
Beyond the high resolution forecasts, FARM has another unique feature: historic forecasts. According to Elizabeth Hawkins, an OSU Extension agronomist based in Clinton County, FARM’s database of forecasts for specific locations is “its most unique feature.”
“This feature gives farmers the ability to look back at the forecasts that were available when they applied the fertilizer,” said Hawkins. “That information is usually quite hard to find.”
In the event that a forecast is wrong, historical forecasts may provide documentation that farmers were operating under proper procedures and working in accordance with forecasts that were accurate at the time.
For example, the Western Lake Erie Basin Partnership sets laws that prohibit farmers from applying fertilizers or pesticides if the forecast calls for over a 50 percent chance of rain.
If the forecast calls for a 20 percent chance of rain and a farmer decides to apply fertilizer only for the rain to fall, the farmer can cite the app conditions for the day.
FARM users can also set up accounts and receive detailed emails notifying them of real-time precipitation alerts and forecasts. As the app expands, Wilson anticipates adding phone alerts that will further streamline the process of keeping farmers in the know.
“This equips farmers with the tools to help them make decisions,” Wilson said.
The app can be viewed on most computers and mobile devices. “It’s very accessible. It’s very easy for anyone to use, and it’s very intuitive,” said Hawkins.
The app provides both economic and environmental advantages.
When warned about precipitation that exceeds good management practices, farmers can avoid using fertilizer and pesticides that are doomed to wash away, saving both time and money. Washed-away fertilizer also makes it difficult for farmers to anticipate how much more fertilizer needs to be added.
“If the fertilizer is washed away, that is one input they have lost,” Hawkins said. If farmers don’t know how much fertilizer and pesticide is actually acting upon their crops, then it’s difficult to predict growth.
The app offers a significant environmental benefit as well by helping prevent fertilizers and pesticides from washing into Ohio waterways.
“If you have too much phosphorus washing into rivers and eventually Lake Erie, you have a greater potential for harmful algal blooms,” Wilson said. “This is detrimental to the waterways farmers depend on.”
It’s no secret that farmers and the environment have a mutual co-dependence on each other. FARM gives farmers a distinct opportunity to look after the environment in a way that also saves them time and money.
