Not surprisingly, an IPM plan for cockroaches in a school will look very different than an IPM plan for soybean aphids in soybean. Details about how to practice IPM in different locations are provided in the table below.
The system assumes grid-wide average conditions for soil moisture. If you know that your fields are particularly wet (for example, you experienced a recent rainfall event that was greater than in other parts of the grid) you should know that the risk of runoff from your fields will be higher than what is shown on the risk map. The opposite may hold true if you estimate that your soil moisture values are lower than the grid-wide average.

Applying liquid manure (typically equivalent to 1/3 to 1 inch or more of rainfall) to wet fields can lead to direct manure runoff, even if the field is otherwise a low risk site due to low slope or low P-index. Make sure your fields are dry enough to accept additional moisture. If liquid manure should runoff or pond in a field or discharge into tile lines, application must stop until the runoff can be checked. Additionally, operating field equipment on wet fields can lead to soil compaction which can greatly reduce crop yields.

An application of 27,000 gallons per acre of liquid manure is the equivalent of adding approximately 1 inch of water to your fields. A liquid manure application effectively increases your soil moisture, and therefore the risk of runoff from fields receiving liquid manure will be higher than what is shown on the risk map.

These are areas of concern on your farm and might include fields with higher slopes, tighter soils, poor drainage, or fields that are closer to sensitive features such as ponds, streams, lakes, wetlands, sinkholes, etc. Many of these areas may be identified in your nutrient management plan. You should use caution when applying manure or any agrichemical products in these areas, regardless of what the risk map indicates.
