One way to think of nutrient management planning is in terms of a "process" that you go through
for each plan you develop. Here are the steps in a typical process for developing and
implementing a Comprehensive Nutrient Management Plan (CNMP):
1. Lay out the farm with GIS software, including field boundaries, conservation practice
boundaries, and manure application setback areas, then export this data to MMP.
2. Develop the nutrient management plan with MMP by entering all production data,
RUSLE2 data and risk assessment data, then planning all manure and fertilizer applications
and manure transfers.
3. Develop the CNMP conservation plan with any production area or land treatment
conservation practices that are already in place or are planned for the farm.
4. Generate the CNMP document and the producer activity document with MMP, then edit the
generated documents to insert maps and additional required text.
5. Submit, review, deliver and archive the CNMP document and its related files.
6. Implement the nutrient management plan and keep records.
Note that this guide covers only steps 2 and 4. For help with the other steps, please consult the
documentation included with the software that you will use to complete them.

2. Before You Start
Be sure to review this section before you begin using MMP.
2.1. Nutrient management planning: What it is
Nutrient management planning can challenge even experienced planners. Not only are there numerous differences between types of animal operations, storage facilities, field limitations, crop needs and equipment capabilities, but there are often differences between what various states and conservation partners want to see out of the planning process.
For the purpose of this guide, nutrient management planning is demonstrating that an animal feeding operation has sufficient crop acreage, seasonal land availability, manure storage capacity, and application equipment to manage the manure produced in an environmentally responsible manner. Theoretically you could do this with a calculator and a piece of paper; in all likelihood, you will probably want to use software like MMP to assist you.
Nutrient management planning can also be done for farms that import and utilize manure, but don't generate any manure. Likewise, plans can be developed for farms that don't have anything to do with manure, using commercial fertilizer to meet all of their crop nutrient needs. MMP can be used with these types of operations as well. However, since both types engage in activities common to an animal operation as far as nutrient management is concerned, they won't be addressed specifically in this guide.
Nutrient management planning is usually long-term and therefore can be described as strategic
planning to emphasize its long-term nature. You can also think of a plan as a feasibility study of
an operation's ability to manage the manure it produces over the period of the plan. 2.2. Nutrient management planning: What it isn't
Nutrient management planning in the context of this guide is not the same as recordkeeping, even though accurate records are vital to revising and updating future plans. MMP includes an optional recordkeeping tool that can be used to record daily manure applications once an operation's long-term plan is complete. However, actual records of manure applications are not entered into MMP. MMP is a forward-looking planning program; recordkeeping programs are backward-looking documentation tools. Decisions about manure management made in MMP can and frequently will change as future conditions warrant; once manure is applied to a field, there's little you can do about it except record what was done.
Nutrient management planning in the context of this guide is not really about short-term decisions either, such as what to do next week or next month, even though these tactical planning decisions
are critically important to managing manure properly and meeting the goals of the long-term plan. 2.3. Collecting good data
Collecting enough data to create a good plan usually requires spending many hours with the producer and possibly several site visits to the operation. At first this may seem daunting. After you've done a plan or two, you will become more efficient and the data collection process should go faster.
MMP includes a blank form that can be used to record most of the data that is required. Another option is to enter data directly into MMP during the data collection process.
Getting Started with MMP Page 3 25-Apr-2008
Some data is more critical than other data. Section 8 discusses some of the pitfalls to avoid with
three of the most critical types of data: soil test results, manure analyses, and annual manure
You'll find that GIS software is helpful in generating accurate field size and soil type data.
2.4. Typical use of the software
Here is a typical sequence for developing a nutrient management plan:
1. Use your GIS software to lay out field and application setback boundaries and determine
field sizes and soil types.
2. Export data from your GIS software to MMP so you don't have to re-enter this data in MMP.
3. Enter the operation's production data in MMP. This includes field, soil test, crop, storage,
animal and equipment data provided by the producer. Field and soil test data can also be
imported – see Appendix B in this guide for help with importing data into MMP.
4. Enter RUSLE2 soil loss data in MMP and run any state-specific phosphorus index or other
risk assessment tool. This provides a baseline estimate of phosphorus risk without any
manure or inorganic phosphorus applications.
Tip: Before you can enter any RUSLE2 data in MMP you will need a RUSLE2 database
(.gdb extension) for your area. The recommended way of obtaining the right RUSLE2
database is to use this Web application. See Section 4 for more information about RUSLE2.
5. Based on the results of the risk assessment tools and other guidelines you develop, use
MMP to plan all manure applications, manure transfers, and commercial fertilizer
applications for the length of the plan.
6. Review the plan by running MMP's built-in and custom reports. In some cases, you may
need to run the state-specific risk assessment tools again to evaluate your application
decisions. The results of this step may require you to revisit the planning decisions made in
7. Generate state-specific reports tailored to meet a range of production and compliance needs.
These may be MMP custom reports, CNMP and similar documents, or other reports that
you compose yourself with a word processor.
2.5. Mastering your computer
To successfully create a nutrient management plan with MMP, you will not only need to become
proficient in using the program, but also in using utility programs such as Windows Explorer to
copy, delete, rename and backup files. Appendix A includes useful tips on organizing your files.
This guide assumes you have a basic understanding of Microsoft Windows. For help with
understanding Windows concepts and conventions, refer to the Windows help or one of the many
books or Web sites on Windows.
2.6. Terminology and assumptions
Make sure that you understand what MMP means by the various terms discussed below before
Getting Started with MMP Page 4 25-Apr-2008
For the purposes of nutrient management planning, a field can be defined as the largest unit of
land that has the following characteristics:
? Same crop rotation, yield goals, and tillage.
? Can be represented by a single soil test sample. Extension fertilizer recommendation
guidelines often limit this to 20-25 acres per soil sample, but this may differ from state to
? If the field will receive manure, the spreadable (non-setback) part of the field can be
completely and uniformly manured in the same month, with the entire spreadable area
receiving similar amounts of available manure nutrients.
Your state may also have guidelines regarding the definition of a field for conservation or nutrient
In general, all parts of a field are managed the same in the context of nutrient management
planning. However, sometimes you may need to subdivide fields into smaller units than what you
might come up with based on the above criteria. Here are some examples of cases where
additional subdividing makes sense:
? If differences in soil type within a field result in different fertilizer recommendations, then it
probably makes sense to subdivide the field by dominant soil type into manageable subfields.
GIS software makes this easy since the soil type boundaries from the county's digitized soil
survey can be displayed on the farm map when you're drawing field boundaries. ? If a risk assessment tool produces different results for significant acres depending on the part
of the field that's assessed, then it probably makes sense to subdivide the field. This could
result from differences in slope, distance to water body, or other field or soil characteristics
used by the risk assessment tool.
? Areas of a field in filter strips and other conservation buffers that are planted to a different
crop than the rest of the field should always be treated as separate subfields. ? Although technically the part of a field within a manure application setback is managed
differently (cannot receive manure) from the spreadable part of the field (can receive manure),
MMP and GIS software allow these areas to be treated together as the same field due to the
irregular field boundaries that often result if subdivided. However, you can subdivide these
fields into spreadable and non-spreadable subfields if you want. Again, GIS software makes
this easy since it displays the outline of the setback areas on the farm map when you're
drawing field boundaries.
2.6.2. Field identification system
You can use whatever system you want to identify fields in MMP. For each field, you enter a
main field ID and an optional subfield ID. The subfield ID is useful if you've subdivided a field in
order to manage the subfields differently. The only requirement is that the combined field ID and
subfield ID must be unique within the plan. Note that you don't have to use subfields, although
they can be extremely useful if you need to subdivide fields as discussed previously. You can also
enter an optional farm ID for each field, although this is not used in field identification within
Here are two common ways of identifying fields in MMP:
Getting Started with MMP Page 5 25-Apr-2008
? Farmer's field naming system, with subfields if you need to subdivide the fields. You can also
enter each field's FSA farm, tract and field number in the columns provided for use as a
secondary field ID.
? FSA tract and field. For example, you can combine a field's FSA tract and field numbers and
enter this as the main field ID and reserve the subfield ID for when you need to subdivide
FSA fields. Or you could enter the FSA tract number as the main field ID and combine the
FSA field number and any subfield number for use as the subfield ID. Note: MMP uses the terms field ID and subfield ID, whereas GIS software may use the terms
field name and subfield name.
2.6.3. Storage facility
In MMP, a storage facility is any collection of manure that can be represented by a single manure
analysis and a single annual manure production estimate for the period of the plan. If a physical
storage facility (lot, pit, etc.) cannot meet these requirements, you may want to consider dividing it into multiple storages in MMP. For example, if the manure's concentration changes
significantly during the course of the year, you may want to define a storage facility for each
season. In conjunction with subdividing the storage, you'll also want to divide the animals into
seasonal groups, targeting each group's manure to a different storage. In this way, each season
can have its own manure analysis and annual manure production estimate. Use the Notes columns
on the Storage and Animals panels to document these divisions.
Tip: If the operation will be importing manure from another operation, be sure to define one or more storages for this imported manure. For more information, see MMP's help.
Tip: If a new storage will be added to the operation during the period of the plan, you can handle this in two different ways. The first way would be to do two plans, one for the period before the
new storage comes on-line and a second plan for the period after the new storage comes on-line.
Another approach would be to do a single plan that includes the anticipated storage and then just
"export" the new storage's manure from the period before it comes on-line. Be sure to document
these "exports" to make it clear that this is manure that never existed and is only being "exported" so that the storage inventory numbers make sense. Also, be aware of state guidelines regarding
changes to the operation that may affect the nutrient management plan.
2.6.4. Animal group
In MMP, an animal group is any logical collection of animals that generate manure that will be
managed. Animals can be divided into groups by species, production phase, physical location on
the operation, or season. For example, with dairy cows that are housed part of the year where all
manure will be collected and on pasture part of the year where only a portion of the manure is
collected, it makes sense to divide these cows into two groups. That way each group can have
different characteristics. The manure produced by each group can be targeted to different storage
facilities as well.
Like storages and animals, equipment can be defined in multiple ways. For example, if the same
tanker will be used both for injecting and surface applying manure, you can define it twice. That
way, each equipment definition can have a different minimum application rate and application

3. Using MMP to Enter Production Data
MMP is the "core" program where you create and enter manure management plan data or add to
the field data brought over from GIS software.
3.1. What you'll need to run MMP
? The latest version of MMP can be downloaded from http://www.agry.purdue.edu/mmp.
? The operation's production and inventory data that you'll enter in MMP. This includes data
about fields, soil tests, crop rotation, manure storage facilities, animal types and numbers, and
application equipment. GIS software can determine some of the field data such as acreage
and soil type. If you're not using a GIS with MMP, you'll need a soil survey map to determine
each field's predominant soil.
? You do not need any additional software to create a manure management plan with MMP.
However, several of MMP's custom reports and tools require Microsoft Office. These
optional custom reports and tools are discussed in Section 7.
3.2. Installing MMP
Run the MMP installer, SetupMMP_xxxx.exe (where xxxx is the program release number). You
can install MMP anywhere you want. By default, MMP will be installed in C:\Program Files (or
C:\Program Files\USDA on USDA-NRCS computers).
Tip: If you have an earlier version of MMP installed, it's always best to uninstall it before installing the latest version. Note that uninstalling MMP and installing the latest version does not delete any MMP plan files you might have created. Select Start | Settings | Control Panel to open
the Windows Control Panel, then double-click Add/Remove Programs. In the Add/Remove
Programs dialog box, select the previous version of MMP to uninstall and click the Add/Remove
button, then follow the instructions.
Tip: Unless you tell it otherwise, MMP's installer will install its files for all supported states. You can uncheck the states you won't use. This will reduce the amount of disk space that MMP will
take up. However, it also means you won't be able to open example plans for those states. If you
have plenty of disk space, it never hurts to install all supported states.
3.3. Running MMP
To start MMP, select the MMP item from the Windows Programs menu. If your computer has an
MMP icon on the desktop, you can also double-click the icon to start MMP.
When MMP runs, it displays a row of buttons at the bottom of its main window. Click the New
button to create a new plan or click Open to select an existing plan file that you created
previously. Once you've created or opened a plan, MMP displays the plan's General panel, the
first of several panels where you enter data. The screenshot on the next page shows what the
General panel looks like for one of MMP's sample plans.

management plan for entering your own plan data. Click the Open button to resume editing
a previously saved plan.
3. Once you've created a new plan or opened an existing plan, MMP displays the plan's
General data panel, the first of several panels where you'll enter plan data. On the panel are
input boxes where you enter data. Press the Tab or Enter key to move to the next input box
and Shift+Tab to move to the previous input box, or click on an input box to jump to it.
When you move to a different input box, MMP displays information about the input box on
the status bar at the bottom of the main window.
4. At the top of the panel are tabs labeled General, Fields, Soil Tests, and so on. Click on a
tab to view its corresponding data panel.
5. Enter as much data as you can for your plan. You can always come back later and fill in
6. To save your plan to a file, click the Save button. To save your plan under another name
(for example, to save a previous version or backup copy of your plan), click the Save As
Getting Started with MMP Page 8 25-Apr-2008
7. To check your data, click the Tools button and click Check Plan's Data For
Completeness on the Tools dialog box's Reports panel.
8. To generate a report showing your fields' nutrient needs, click the Tools button and click
Report Annual Field Nutrient Needs.
9. Use the Nutrient Mgmt panel to plan manure applications, manure transfers, and
commercial fertilizer applications for each year in the plan.
10. To generate a report showing your fields' nutrient balance as a result of the planned
manure and fertilizer applications you entered on the Nutrient Mgmt panel, click the Tools
button and click Report Field Nutrient Balance. 3.5. Quick tips on entering data
1. F1 for help. If in doubt about what to enter, press the F1 key to display help for the current
data panel or dialog box. If you don't know how to use help with Windows, press the F1 key
from within help.
2. Status bar hints. When entering data, the status bar at the bottom of the main window
displays a brief description of the type of data expected for the current input box or grid
column. If in doubt about what to enter, glance down at the status bar for a hint.
3. Undo. To undo typing changes that you've made to an input box, press Ctrl+Z. Note that
this works only if you haven't moved from the input box. You can also right-click on the
input box and choose Restore from the popup menu to undo typing changes.
4. Copy and paste. To speed up entering the same data into several different input boxes,
press Ctrl+C to copy the highlighted contents of an input box to the Windows clipboard.
Then move to a different input box and press Ctrl+V to paste the clipboard contents into
that input box. You can also right-click on an input box and choose Copy or Paste from the
5. Operating a pick list. To pull down a pick list with the mouse, click the arrow on the right
side of the pick list box. To close the pick list without selecting anything, click the arrow
again or click anywhere outside the pick list. With the keyboard, press Alt+ to pull down
the list. Press Alt+ again to close the list.
6. Pick list shortcut. To speed up entering data with a pick list, type the first letter of the
desired item's name to select the first item that starts with that letter. If there's more than one
item starting with that letter, you can continue typing that letter to cycle through the items.
Note that this works even if the list is not pulled down. For example, when selecting crops,
you can simply type C to select Corn without even pulling down the list. (When cycling
through the list, don't pause between keystrokes. If you pause, the search is reset. Also, if
you type quickly, you can continue typing additional letters of the desired item to jump to it.
For example, quickly type CR to select CRP.)
7. Blanking out a pick list. To blank out a pick list box, scroll to the top of the list and
choose the first item, which will either be blank or, if the pick list is in a grid, (None). With
a grid pick list, you can also just press the spacebar to select (None) without pulling down
8. Sorting a data entry grid. To sort the Fields, Soil Tests, Storage, Animals, Analysis or
Equipment grid, simply right-click on the header row of the column you want to sort the
grid by and choose Sort Ascending or Sort Descending from the popup menu. Getting Started with MMP Page 9 25-Apr-2008
9. Deleting or inserting a field. To delete a field or insert a new field, on the Fields panel
right-click the indicator column (?) of the field you want to delete or the row where you
want to insert a new field. Choose Delete Field or Insert Field from the popup menu. 10. County. In the County pick list, be sure to select the county where the crop fields are
located, not the county of the operation's mailing address.
11. Irrigation. Since irrigation affects fertilizer recommendations in some states, be sure to
indicate if a field is irrigated by checking the Irrigation column for the field on the Fields
12. Cover crop. If a field will have a non-harvested cover crop, scroll to the right on the
Crops panel and select it in the Planned Cover Crop column for each year that it will be
planted. Do not enter a yield goal. Note that fall-seeded single-cropped small grains that
will be harvested the next year should be selected in the Planned Crop column.
13. Proofing data. Enter as much of the operation's data as you can, then click the Tools
button and click Check Plan's Data For Completeness to see if any required data is
missing or if there are any inconsistencies in what you've entered. To check if you've
entered enough soil test data, look at the Default N Rec, Default P2O5 Rec and Default
K2O Rec columns on the Crops panel. If any of these is blank for a crop, then some of the
field's soil test data (or the crop's yield goal) is missing.
14. Close button to back out. Click the Close button to abandon any changes that you've
made since the plan was last saved. You can use this the same way you use the File | Close
menu command in a word processor or spreadsheet.
15. State-specific notes. Be sure to review any notes specific to your state. Click the State-
Specific Notes topic in MMP's help.
16. Frequently Asked Questions (FAQs). Read through the list of FAQs in MMP's help or
MMP's Web site. The first time you read them, some questions or answers may not make
much sense to you. Go back and read them again after you've used MMP for a while. To
print a copy of MMP's FAQs or any other help topic, select the help window's File | Print
Topic menu command.
17. Reporting problems. If you have questions about MMP or problems operating it, please
contact the authors. Click on the Reporting Problems To The Authors topic in MMP's
help for contact information. Contact information is also available on MMP's Web site.
18. Making screenshots. To take a shot of the current MMP window or dialog box and paste
the shot into a PowerPoint or Word document, press Alt+PrntScrn. To take a shot of the
entire screen, press PrntScrn. This copies the window or screen contents to the Windows
clipboard. In PowerPoint or Word, press Ctrl+V to paste the screenshot into the document.
