  1. Growing, the Nutritional Angle Modified by Georgia Agricultural Education Curriculum Office July, 2002 Walter N Nelson Extension Educator, Horticulture South Central New York

  2. Today’s Goals • Provide an overview of growing media and fertilization for floriculture crops • Equipment for Your ‘Nutrition Tool Box’

  3. Water and Water Quality • Its most of our crops and relates directly with growing medium, fertilizer and your management practices • Issues: hardness & mineral content • pH, impacting micronutrient availability • Alkalinity measure of capacity to neutralize acids • acid injection reduces bicarbonates (sulfuric, phosphoric citric or citric)

  4. Ingredients for Growing Medium • Ingredient ratios • Peat • Coir • Peat-Lite Mix • Mineral Soil • Composts

  5. The Fertilizer • Organic • Synthetic • Water soluble • Slow release • Controlled release or encapsulated (CRF) • Macro nutrients • Micro Elements

  6. Nutrition Related Symptoms • Descriptions • Picture clues

  7. Application Technology • Venturi • Gewa • Hozon

  8. Application Technology • Venturi • Gewa • Hozon • proportioner injector • positive displacement • turbulence • Anderson

  9. Application Technology • Venturi • Gewa • Hozon • proportioner injector • positive displacement • turbulence • Anderson • Dosatron • Dosmatic

  10. Application Technology • Venturi • Gewa • Hozon • proportioner injector • positive displacement • turbulence • Anderson • Dosatron • Dosmatic • Smith

  11. Methods of Application • Top-down • Subirrigation • NFT, constant flow • Trough • Ebb/flood

  12. The Math • Volume per bale • Depth of mix in pots • Developing a fertilizer program • Dilution ratio • pH • TSS • PPM • (% fertilizer) (.75)  PPM of 1 ounce/100 gal

  13. Testing • Media • Foliar • Laboratories

  14. Resources • Greenhouse Engineering (NRAES 33, available from CCE) • Greenhouses for Homeowners and Gardeners (NRAES 137, available from CCE) • Water and Nutrient Management for Greenhouses (NRAES 56, available from CCE) • http://www.ces.ncsu.edu/depts/hort/hil/flowers-index.html

  15. Summary • Water • Medium • Nutrition • Equipment • Help Let’s Get Growin’!
