  1. Soil Organic Matter Accumulation at the George Jones Farm: A comparison of organic treatments with natural processes and conventional management December 10, 2003 Nathaniel Decker, Kate Merrick, Tina Bosch

  2. SOM and Organic Farming • Soil Fertility • Importance for Organic vs. Conventional Farming • OSAP aims to increase SOM • Treatment Types

  3. Treatments Note: C/M- COVER CROPPED AND MOWED FOR 3 YEARS CHX- CHICKEN TRACTOR LM- LEAF MULCH XLM- EXTRA LEAF MULCH M- MANURE 1,2- YEARS IN CULTIVATION

  4. SOM and Organic Farming • Soil Fertility • Importance for Organic vs. Conventional Farming • OSAP aims to increase SOM • Treatment Types • OSAP would like to know what effects the organic amendments used have on SOM

  5. Objectives and Hypotheses • Organic management increases SOM - conventional management - pre-OSAP SOM • SOM content will be higher in proportion to amount of organic amendments - GH>N & S Beds> Orchard • Will the Wetland Edge also increase SOM?

  6. Methods • Soil cores • Loss-on-ignition • Sampling sites

  7. Site Map

  8. North Beds South Beds

  9. OSAP SOM 10% A 9% 8% 7% B, C 6% B B, c B, c B 5% SOM Content C 4% 3% 2% 1% 0% North Beds South Beds Wetland Edge Fallow Field Neighbor Orchard Greenhouse Beds Results

  10. OSAP SOM 10% A 9% 8% 7% B, C 6% SOM Content B B, c B, c B 5% C 4% 3% 2% 1% 0% North Beds South Beds Wetland Edge Fallow Field Neighbor Orchard Greenhouse Beds Analysis • Greenhouse – high • Fallow Field – low • No significant differences among treatments • Neighbor – lower than GH but not other organic treatments • Wetland indistinguishable from treatments • SOM increased since 2000

  11. SOM in 2000 at OSAP

  12. Recommendations/Lessons • Experimental setup would be helpful - effect of different crops - cause and effect in GH

  13. Shout Outs • Yay Greenhouse! • Yay Amendments! • Further study to determine precise mechanisms for SOM increase

  14. Acknowledgments JP and his lab Brad and his farm Becca and her car A Group Phoenix Production
