What is SNMP?
The Spatial Nutrient Management Planner (SNMP) is a decision support tool that facilitates the collection, analysis, and presentation of spatial information related to nutrient management planning.
What can SNMP do?
- Use SNMP to delineate farm and field boundaries and local features such as location of streams, wells, ponds, and neighbors and SNMP will automatically show resulting setbacks required for manure application. SNMP's map button will automatically create a farm map showing these setbacks.
- Use SNMP to automatically create soil test maps of the farm and generate fertilizer recommendations for selected crops by entering soil test data for each farm field. (Note that SNMP does not handle grid soil sample data). See the soil test map example below.
- Use SNMP to determine manure distribution networks for the operation. SNMP will calculate the distance from the field to the manure storage. We are also incorporating the digitized soil survey layer into SNMP.
- Export with the click of a button the field identification and soil test information collected in SNMP to Purdue University's Manure Management Planner (MMP).Information gathered by SNMP can also be exported to Purdue University's WinMax program.

What are the system requirements to run SNMP?
- ESRI's ArcView desktop GIS software, version 3.x or higher, preferably 3.2 or 3.3. (Note: This program does not currently support ArcView/ArcGIS 8.x or 9.x)
- Approximately 15 MB of hard drive space. Add about 37-50 MB of hard drive space for each full-size DOQQ file added or 90-150 MB for each full-size color/infrared DOQQ file added.
- Screen capable of at least 800x600 pixel resolution
More About Spatial Nutrient Management Planner:
SNMP requires you to have ESRI's ArcView desktop GIS software on your computer, version 3.1 or higher, preferably 3.2 or 3.3 (not currently available for ArcView 8.x or 9.x). SNMP automatically sets up the ArcView fields needed for nutrient management planning and provides easy-to-use interactive tools dedicated to nutrient management planning activities. By clicking a button in the Options menu, SNMP gives you access to the full complement of ArcView tools. For an example, see the image of the SNMP interface above.
A sample of an automatically generated ratings map from a Bray-I Phosphorus soil test is shown below:
The content of the SNMP was designed by John Lory, an Environmental Nutrient Management Specialist with the University of Missouri-Columbia Department of Agronomy. The design of the tools and scripts of the SNMP software has been an ongoing project at CARES, and is currently being undertaken by Arin Stark, GIS Specialist at CARES.
