Nutrient Management Plan
A nutrient management plan (NMP) is a plan that uses manure as a fertilizer in an agronomical manner to meet realistic crop yield goals. This allows manure to be used in an environmentally and economically friendly manner. The two main nutrients of concern from manure are nitrogen (N) and phosphorous (P). Excessive N from manure may leach through the soil and into groundwater or runoff into surface water. Excessive P causes greater concern, because it takes less P than N to cause harm. Phosphorus in runoff to surface waters creates algae blooms and leads to low levels of oxygen in water (anoxic conditions). This increased stress on aquatic organisms may lead to death, altering food webs and water ecosystems.
