  1. Definition and Classification of Terminologies in Environment Agricultureand Utilization of Spent Mushroom Compost for Organic Transplant Production May 19, 2005 Vegetable Science Lab. Yurina Kwack

  2. Definition and Classification of Terminologies in Environment Agriculture

  3. Organic agriculture Biological agriculture Natural agriculture Environmentally conserving agriculture Environmentally friendly agriculture Sustainable agriculture Ecological agriculture Green food Terminologies in environment agriculture

  4. New definition and classification

  5. Environment agriculture • Economically efficient agriculture that assures the stable production and supply of safe agricultural products and preserves the environment by harmonizing it with agriculture • The most inclusive terminology

  6. Environmentally compatible agriculture • Agriculture that utilizes the developed agricultural • technologies harmonizing them with the environment to minimize the side-effects of chemical agriculture and • decrease in production

  7. Low input agriculture • Agriculture that utilizes integrated pest management (IPM) • and integrated nutrient management (INM) to minimize input of chemicals

  8. Precision agriculture • Agriculture that utilizes geographic information system • (GIS) and global positioning system (GPS) to precisely control the input of chemicals and energy

  9. Environmentally friendly agriculture • Agriculture that utilizes environmentally-friendly methods • such as soil improvement and non-use of chemicals • to minimize environmental pollution

  10. Organic agriculture • Agriculture that applies only organic materials and minerals • to enrich the soil and that utilizes biological and physical methods to control plant diseases and insects

  11. Natural agriculture • Agriculture that utilizes self-made composts, aboriginal • enzymes and microorganisms and that does not apply tillage, • pruning nor chemical fertilizers and pesticides

  12. Environmentally conserving agriculture • Agriculture that links crop production with livestock farming for reducing environmental loads to sustain the ecosystem

  13. Local circulation agriculture • Agriculture that links crop production with livestock farming in a region to utilize crop residuals and manures as animal feed and compost, respectively

  14. Social circulation agriculture • Agriculture that links livestock farming and/or organic • fertilizer production in a certain region with crop • production and/or residual-feed production in other regions • to make a large-scale circulation of bio-materials • domestically or internationally

  15. Utilization of Spent Mushroom Compost as a Growing Medium for Organic Transplant Production

  16. Objectives • To examine the feasibility of recycling the Spent Mushroom Compost (SMC) for organic transplant production • To develop new growing medium for organic transplant production • To investigate the growth and quality of organically produced transplants of several vegetables

  17. Materials • SMC left over from a “Baeckilsongi” mushroom factory of the Pulmuone Takara Ltd. • Hgpsizygus marmoreus

  18. Soybean hull Rice bran Corn cob Sawdust Ingredients of mushroom compost

  19. A few days after germination…

  20. Ready to harvest…

  21. Chemical analysis of SMC before processing

  22. Leaching

  23. Decomposition • A compost maker • Microbial decomposers

  24. Mixing SMC & organic media • Other organic media : Peat Moss & Cocopeat PM: Peat Moss CP: Cocopeat L: leached D: decomposed

  25. Plant growth

  26. Schedule

  27. Study in Japan • To study environment agriculture in Japan • To study natural enzymes & efficient-microorganism • for organic culture

  28. Expected publications • Journal of the Korean Society for Horticultural Science • Journal of the Japanese Society for Horticultural Science • HortScience

  29. -The End-
