Frequently Asked Questions About NMAN

Q. Does NMAN3 replace NMAN 2.1?

A. Yes. NMAN3 replaced NMAN 2.1 in December 2012. NMAN3 has the same functions as NMAN 2.1, in addition to NASM planning functions.

Q. Can I still use NMAN 2.1 to prepare Nutrient Management Strategies and Plans (NMS/P)?

A. No. As of June 15, 2013, all Nutrient Management Strategies (NMS) submitted for approval must be prepared with the current version of NMAN3.

Q. Where does NMAN store my files?

A. NMAN files save as ".nm3" or ".nm2" files (depending on the version you are using), which can be stored anywhere on your computer. When you install a new version of NMAN, the program automatically selects the 'My Documents' folder to save NMAN files. Once you have used NMAN, the program will default to where you last saved and opened a file.

Q. How do I print from NMAN?

A. NMAN generates reports as a Portable Document Format (PDF) document. You need a PDF reader program to open and print the reports.

Steps to printing a report from NMAN3:

  1. Click on the "Print" icon on the "Main" toolbar and select the report you wish to print.
  2. Click the "Print (PDF)" button to create a PDF file.
  3. Name and save the PDF file.
  4. Open the PDF file with a PDF reader program to print.

If you do not have a PDF reader installed on your computer, you can visit the Adobe website and download the Acrobat Reader for free.

Q. What do the different flags represent in NMAN?

A. NMAN uses a colour coded flagging system to alert users to practices that may result in a violation of the Nutrient Management Act (NMA) or a practice that is contrary to Best Management Practices (BMPs). The flags will tell you how the practice impacts your plan. Hover your mouse over the flag in NMAN to get more information on each flag.

Q. What should I enter for the "Operation ID" on the "Farm Unit" screen in NMAN?

A. You should leave this field blank until you receive an Operation ID (OPID) for your NMS in your acknowledgement letter from the Ministry of Agriculture and Food and the Ministry of Rural Affairs. Once you receive the OPID, enter it in your NMAN file for future communication about your NMS.

Q. Can I open a file created in an older version of NMAN in NMAN3?

A. Yes. NMAN3 opens and upgrades files created in NMAN 2.1. Once the upgrade is complete, it is important to update the flags and calculations in your file. We recommend that you review the entire file because many calculations and values have been updated that may affect previously calculated values.

Q. How do I represent manure deposited on pasture in NMAN?

A. When adding a livestock type, you can select the pasture manure form. Using the input fields on the Livestock Information screen, enter the appropriate utilization time that your animals will be on pasture. Pasture material is represented as Grazing Units (GU) and is not included in the "material remaining" calculations.
