St. Brigid's Farm


  • Agronomic: barley, corn, soybeans, grass (misc. perennial), hay
  • Animal Products: dairy


  • Animal Production: grazing - continuous, feed formulation, feed rations, manure management, mineral supplements, pasture fertility, grazing - rotational, feed/forage
  • Crop Production: nutrient cycling, application rate management
  • Education and Training: farmer to farmer, on-farm/ranch research
  • Production Systems: agroecosystems
  • Soil Management: organic matter, soil analysis, soil quality/health
  • Sustainable Communities: sustainability measures

    Proposal summary:

    Nutrient flow on dairy farms that graze intensively can be problematic—nitrogen and phosphorus accumulations can occur. The farmer will monitor nutrient flow, reduce the phosphorus and nitrogens in imported feed, make more efficient use of fertilizer, and evaluate the overall nutrient management balance using tools developed at the University of Maryland.
