Research and OUTREACH Projects
- The Root Zone as a Bio-Filter: Making Soil a More Effective Treatment Media for the Remediation of Enteric Pathogens: Evaluation of selected cool season (C3) warm season (C4) grasses as bio-filters for capturing enteric pathogens in the root zone for remediation and nutrient recovery.
- Evaluation of Low-Disturbance Tillage in Mitigating the Transport of Bacterial Contaminants from Land Applied Dairy Slurry to Subsurface Drains: This work will help to identify an environmentally responsible and site-specific application rate based on the ability of the soil to retain and process manure nutrients and contaminants in the root zone.
- Improving Soil and Seedbed Quality in Sugarbeet Rotations with Slurry-Enriched, Micro-Site Seeding of Biosuppressive Cover Crops: Development and testing of a manure application process that incorporates seeding of biosuppressive cover crops in sugar beet rotations.
- Integrating Environmentally Responsible Manure Use and No-Till Forage and Cropping Systems with Low-Disturbance Aeration Tillage: Evaluate the quality, botanical diversity and biomass yields of orchard grass and red clover seeded in a smooth brome grass sod using slurry enriched micro-site seeding with crops established using conventional no-till and frost seeding techniques. Evaluation of aeration tillage and a wheat cover crop on nitrogen availability in no-till corn production following a fall manure application.
- Stabilizing Nutrient-Rich Farm Land in the Great Lakes Basin: Project goals are to establish an integrated tillage and manure management demonstration project in southeast Michigan, establish a soil stabilization project to evaluate the use of aeration tillage and manure use in cover crop establishment on corn silage ground, and evaluate the effect of a multi-barrier approach to soil and manure stabilization on runoff and subsurface drainage water quality.
- Integrating Cropping and Nutrient Management Systems on Grass-Based Dairies with Manure Slurry Enriched Micro-Site Seeding: Evaluation of a low-disturbance aeration tool to create seeding micro-sites in established pasture ground, and then using nutrient-rich manure slurry as a carrier to deliver forage grass and legume seeds to the seeding sites without destroying the existing forage.
- Using Spatial Technologies to Evaluate the Grazing Behavior of Dairy Cattle on Manure-Applied Pasture: Use of spatial technologies to monitor, map, display and analyze the grazing preference and dry matter intake of dairy and beef cattle on manured and untreated pasture ground. An objective is to determine a reasonable delay between manure application and the introduction of cattle based on grazing preference.
- Change Detection and Analysis with GIS in Manure-Applied Pasture Land: Use of geographic information systems to monitor, map, display and analyze changes in forage grass and legume species richness and biodiversity in manure applied and untreated pasture land.
