Our Research

Entomology
   led by Mike Koch, CSU
What's "bugging" your field?
Nutrient Management
   led by Merle F. Vigil,
USDA-ARS
Nutrient management research at the Central Great Plains Research Station is comprised of studies to determine:
 
  • Nutrient Cycling relationships in traditional and alternative crop rotations with emphasis on C (carbon) and N (nitrogen)
  • Nitrogen fertilizer use efficency in sunflowers, corn, proso-millet and winter wheat
  • Fertilizer recovery as affected by fertilizer placement
  • N mineralization and N immobilization from animal manuers, soil organic matter and crop residues
  • Loss of standing crop residues as affected by wind run, management and chemical application
  • Legumes as a source of organically derived N
Soil Matrix
  led by Joseph Benjamin,
USDA-ARS
Soil matrix research at the Central Great Plains Research Station is comprised of studies to determine:
 
  • Effects of soil compaction on plant growth and productivity
  • Effectiveness and longevity of compaction alleviation methods
  • Changes in soil porosity, water holding capacity and hydraulic conductivity caused by crop rotation and soil management
  • Crop rotation and soil management effects on surface crusting, infiltration, and potential erosion
Soil Quality
 
led by Maysoon Mikha
USDA-ARS
Soil Quality research at the Central Great Plains Research Station is comprised of studies to determine:
 
  • Nutrient cycling, specifically nitrogen and carbon
  • Organic matter dynamics
  • Soil quality
Water Management
 
led by David Nielsen
USDA-ARS
Water management research at the Central Great Plains Research Station is comprised of studies to determine:
 
  • Crop water use/yield relationships and soil water extraction patterns of traditional and alternative crops
  • Non-crop period precipitation storage in the soil profile
  • Interactions between weather and crop sequencing on soil water availability and subsequent crop yield
  • Crop residue effects on snow catch and soil water evaporation
  • Effect of time of water stress on crop development and yield
Weed Science
 
led by Brien Henry
USDA-ARS
Weed Management research at the Central Great Plains Research Station is comprised of studies to determine:
 
  • Weed species shifts in response to tilling practices
  • Herbicide resistance issues
  • Gene flow from transgenic crops to conventional crops and/or weed species
  • Remote sensing; site specific weed management
