Organic Gardening Rodales The organic gardeners bible National Organic Program Developed national organic standards and established an organic certication program National Organic Program Organic crops are raised without most conventional pesticides petroleum-based fertilizers sewage sludge-based fertilizers National Organic Program Prohibits GMOs As a general rule, natural substances are allowed Synthetic substances prohibited Does Natural Mean Organic? Natural and organic are not interchangeable Free-range, hormone-free, and natural don't mean organic Certification Accredited by USDA-accredited certifying agents The information an applicant must submit organic system plan substances used record keeping Organic Materials Review Institute (OMRI) National nonprofit organization that determines which products are allowed for use in organic production OMRI products Crop Scheduling Burpee endarWithZipCode.jsp?catid=1000&_reques tid= endarWithZipCode.jsp?catid=1000&_reques tid= Southeastern States vegetable-guide/pdf/vegetable-guide/pdf/ Clemson ants/vegetables/gardening/hgic1256.htmlants/vegetables/gardening/hgic1256.html Log Gardening Hugelkultur Bury logs in a mound Retain moisture Decomposition provides Nutrients Aeration Boosts microorganisms Heirloom Plants Open-pollinated Grown in an earlier era Before 1951, before hybridization became popular Better flavor Cover Crop P024_covercrop.pdfP024_covercrop.pdf Cover Crop Catch Crop Reduce nutrient leaching Cover Crop Improve soil Increases organic matter in soil Improves soil structure Increases microbial activity Cover Crop Natures fertilizers Nitrogen production from legumes Clover, beans, peas, vetch Cover Crop Rooting can aerate soil Blue lupine a biological plow in compacted soils Cover Crop Weed suppression Smother weeds Allelopathic effects Inhibit or slow growth of weeds by releasing natural toxins, or allelochemicals Small grains (rye), sorghum, sudangrass Companion Planting Certain combinations have synergistic effects Improve growth Prevent pests Attract beneficials Companion Planting Rose and garlic Tomatoes and cabbage Corn and beans Crop Rotation Dont grow the same crop in the same soil year after year Crop Rotation The longer the rotation, the better the results 4-year rotation: Corn, soybeans, oats, alfalfa Break up insect and disease life cycles Reduce weeds Improve soil nutrition Crop Rotation Iowa State University Marsden Farm rotation experiment started in 2003 The longer rotations produced better yields Reduced fertilizer/herbicides up to 88% 2/10/19/a-simple-fix-for- food/?_php=true&_type=blogs&_php=tru e&_type=blogs&_r=12/10/19/a-simple-fix-for- food/?_php=true&_type=blogs&_php=tru e&_type=blogs&_r=1 Organic v.
