Research Accomplishments:

  • Developed soil-grouped economic nitrogen (N) fertilizer recommendations in the early 90’s for Wisconsin replacing yield-goal and that are now the basis for N recommendation systems affecting 59% of the corn grain produced in the USA.  
  • Pioneered the use of polymers for efficient solid-liquid separation of manure, which is now a key component used in manure treatment systems worldwide.  
  • Discovered a method to extract phosphorus from livestock wastewater using a new theory. It uses fewer chemicals than other methods and recovers the P in a reusable form.  
  • Discovered and patented a high-performing nitrifying sludge (HPNS) for effective nitrification under cold conditions which allows affordable wastewater ammonia treatment in farms. More Information
  • Developed new concepts for effective green-house gas (GHG) reduction and carbon credits using aerobic treatment of manure recommended by USDA for GHG mitigation.  
  • Invented and developed a policy-changing waste treatment system without lagoon, awarded environmentally superior technology (EST) by meeting standards for pathogens, odor, ammonia emissions, nutrients, and heavy metals. More Information 
  • Co-invented the Quick Wash method to extract P from poultry litter. This pioneering agricultural waste technology crossed discipline boundaries and is being adopted in municipal markets. More Information 
  • Invented new methods for recovering ammonia and reducing gaseous ammonia from animal production operations using gas-permeable membranes. More Information 
  • Isolated from manure and patented a new anammox bacterial species (Brocadia caroliniensis) used by NASA to develop water treatment systems for space exploration. More Information 
  • Invented a new method to extract amino-acids and phosphorus from manure and algae.  More Information
