Area of Focus

Soil Science/Crop Nutrition

Research Interests

Design cropping systems that make effective use of materials used to improve crop nutrition and prevent environmental contamination. Lead an integrated organic cropping systems conversion project at the Haskell Agricultural Laboratory. My emphasis is on maintaining soil fertility within an organic cropping system.

Extension Interests

  • Promote the effective use of fertilizers, organic amendments and other cultural practices to optimize production and profit without causing contamination to the environment.
  • Collaborate with Natural Resources Districts to provide targeted nutrient management programs designed to reduce nitrate contamination of groundwater.

 

Major Project Activities

Utilizing manure in an efficient and environmentally sound manner is a focus of both research and extension activities. As co-leader of the Comprehensive Nutrient Management Planning workgroup, we published the Manure Application Workbook that is a step-by-step guide to preparing a farm plan that utilizes manure nitrogen at agronomic rates. Our website features many educational publications and tools to manage manure. It is updated as new information and tools are available. We recently completed a study of the phytotoxic effects of swine manure sprayed on crops during the season and are developing application guidelines that maximize nutrient utilization without causing crop damage.

In addition to the above, we also have collaborative water quality programs with several Natural Resources Districts, USGS, and NRCS. My interest is in nitrogen management. We collaborate with irrigation engineers since water management affects nitrogen losses.

Initiated in 2004 is a project to determine the nitrogen credit for corn following soybeans grown on irrigated sands in north central Nebraska.

More details on this project and others is available at the http://cropwatch.unl.edu/soils website.
