  • Agronomic: oats, rye


  • Crop Production: cover crops, nutrient cycling
  • Education and Training: demonstration, on-farm/ranch research
  • Pest Management: competition, smother crops
  • Soil Management: green manures, organic matter, soil analysis, nutrient mineralization

    Proposal summary:

    This on-farm demonstration will use a mixture of rye and vetch as a winter cover crop, along with other mixtures, to achieve as much organic matter as possible without tying up nitrogen. The farmer will conduct weekly soil tests in each plot to monitor nitrate fluctuations. The goal is to demonstrate nitrogen availability with various cover crop mixes and decomposition rates after tillage.
