reconciliation on each field’s nutrient management plan.)

Manure sample analysis. We want this to only affect the last plan year prior to
reconciliation, and those years following. Not the years before. The assumption is
that the manure sample in prior years was good but the plan year sample was/may
not have been available until after the manure was applied.
Years 2 thru 4:
a. Crop—Crop rotation may change for any of a number reasons.
b. Yield—Actual crop yield will almost certainly be different from expected
yield, which is a five year rolling average minus disaster years plus a
small percent genetic increase.
c. Season—Actual season of application may change or it may be split
between spring/fall.
d. Application rate—Actual rate will almost certainly be different from the
planned, and could affect the plan for subsequent years.
e. Mineralization factor—This probably won’t change but it could,
depending on the manure source.
f. NH4-N application loss—This would probably only change if the
application method and/or manure source changes.
g. Other legume credits—Needs to be accounted for.
h. Incidental N—Same as g.
i. Incidental P—Same as g.
j. Incidental K—Same as g.
