Slide 1Achieving Effective Conservation in the Upper Mississippi River Basin

CEAPConservation Effects Assessment Project

1What CEAP Reveals Overview of the Upper Mississippi Basin Slide 2Conservation practices workComprehensive planning is needed because suites of practices work better than single practicesTargeting critical acres improves effectiveness significantlyThe most critical conservation issue is reducing the loss of nutrients, especially nitrogen

Slide 3What CEAP Reveals Conservation Practices WorkProtected SoilUnprotected SoilCompared to no conservation practices:Sediment loss reduced by 69 %Total phosphorous loss reduced by 49 %Total nitrogen loss reduced by 18 %Pesticide risks to human health reduced by 48 % 3 Slide 4What CEAP Reveals Comprehensive Planning is Needed Surface nitrogen losses reduced by 46 % BUT subsurface losses are reduced by only 5 %

Without nutrient practices, erosion control practices can increase subsurface nitrogen losses

4 Slide 5What CEAP Reveals Significant Progress Made in Reducing Erosion and Sedimentation45 % of the cropland and 72 % of Highly Erodible land has structural practices

95 % of the cropland has reduced tillage, 71 % is no-till or mulch till

Edge of field sediment loss reduced by 69 %

In-stream sediment reduced by 37 %

Slide 6What CEAP Reveals Progress Has Been Made, but Opportunities Exist to Expand Nutrient Management Phosphorus losses have been reduced by 49 % but nitrogen losses have been reduced only by 18 %About 60 % of the cropland needs nutrient management, but much can be done. Examples:Timing Nitrogen is fall-applied on 45 % of the cropland acresRate Nitrogen is applied at rates greater than 1.4 times removal at harvest on 66 % of the croplandMethod Nitrogen is not soil incorporated, banded, or foliar/spot treated on 44 % ofcropland acres

6What CEAP Reveals Conservation Practices Reduce Pesticide Risks Significantly Slide 7Pesticide risks to human health are very low on average, only 1 % to 2 % of the pesticides applied are leaving fieldsConservation practices have reduced the pesticide threats to human health by 48%Much can be done to further reduce pesticide losses: Rotations, Scouting, Precision Application

Slide 8What CEAP Reveals Cropland is Gaining Organic CarbonCropland in the Upper Mississippi Basin sequesters about 7.5 million tons of carbon dioxide equivalents (CO2e) annuallyThis offsets the combustion of 0.75 billion gallons of gasoline, enough gasoline to power about 1.3 million cars for one yearThe average cropland acre, with existing conservation, has an annual net gain of 259 pounds of CO2e5 % of the cropland is losing greater than 670 pounds of CO2e5 % of the cropland is gaining more than 1,000 pounds of CO2eErosion control practices can significantly increase sequestration rates by reducing losses of organic matter due to erosion.

Slide 9What CEAP Reveals Targeting Conservation Increases its Impact Targeting the most critical acres, compared to acres that have limited needs, increases practice effectiveness per acre:Over 5 times in reducing sedimentOver 4 times in reducing total NitrogenOver 3 times in reducing total Phosphorus

The CEAP report is the beginning, additional information is needed for implementation:Soil leaching and run-offvulnerability mapsSmall watershed modelingStakeholders inputWater quality monitoring data

Slide 10So What?Voluntary, incentive-based conservation works.Reduced tillage is used on 95 % of the cropland - sediment losses reduced 69 %.Nutrient management is the greatest need. Much can be done through expanded adoption of existing practices.Targeting can greatly enhance program effectiveness.Treating the most critical acres can have 3 to 5 times the benefit of treating acres with less serious problems.Comprehensive conservationplanning is essential.Suites of practices that address multiple resource concerns are more effective than single practices.
