Major Research Project Activities

Dr. Blanco’s research and teaching program responds to the needs of Nebraska agriculture and beyond. He emphasizes on the application of scientific principles of soil management and applied soil physics to meet the increasing demands for food, feed, fuel, and fiber while enhancing soil ecosystem services. His professional contributions in major areas include:

CONSERVATION AGRICULTURE

Dr. Blanco is assessing no-till, reduced till, and conventional till impacts on soil physical and hydraulic properties and soil C in different environments. His team is answering the following: Does no-till improve soil ecosystem services in all environments? Does no-till sequester soil C more than tilled systems? How can we enhance the potential of no-till?

Among his >30 journal articles in this topic include:

CROP RESIDUE MANAGEMENT

Crop residues such as from corn are often grazed or baled for expanded uses; but their impacts on soil ecosystem services are still not well understood. Dr. Blanco is addressing: How much residue can we remove from rainfed and irrigated regions? What are the short and long-term effects of crop residue grazing and baling on soil services?

Among his >30 journal articles in this topic include:

  • Rakkar, M.K., H. Blanco-Canqui, R. Rasby, M.E. Drewnoski, and R.A. Drijber. 2019. Short-term impacts of cattle grazing and baling of corn residues on soil properties in the Central Great Plains. Agron. J. 111:109-121.

COVER CROPS

Dr. Blanco’s team is addressing: Do cover crops deliver all soil ecosystem services in all soils? How does cover crop grazing and harvesting affect soil ecosystem services in the central Great Plains? Can cover crops offset the adverse effects of crop residue removal on soil services? What strategies can we use to increase cover crop biomass yield?

DEDICATED ENERGY CROPS

Growing dedicated bioenergy crops (i.e., switchgrass) in marginal lands can be an alternative to corn residue removal while enhancing soil ecosystem services, but field research is limited. Dr. Blanco is fulfilling this need by assessing biomass production, soil erosion, soil physical processes, C sequestration, and others in perennials grown on marginally-productive lands.

BIOCHAR AND OTHER ORGANIC AMENDMENTS

Dr. Blanco’s team is studying how addition of C-enriched amendments such as biochar other amendments (i.e., manure) affects crop yields, C storage, and soil properties in degraded or low organic matter semiarid soils.
