Presentation Transcript

  1. Fertilizer Terms Nitrogen-Phosphorous-Potassium Macro Nutrients

  2. Incomplete Fertilizer- • Fertilizer containing only one or two of the three major nutrients Nitrogen- Phosphorous- Potassium Example: 34-0-0 Ammonium Nitrate

  3. Granular- • Small pelleted form of dry fertilizer

  4. Slow Release- • Fertilizer designed for release over an extended period, may be large pellet or prill

  5. Polymer-coated Urea

  6. Liquefied gas- • Gas injected under pressure into soil by long tubes ended with blades

  7. Complete Fertilizer • Fertilizer containing percentages of Nitrogen, Phosphorous, and Potassium

  8. Prill • Slow release fertilizer-dry fertilizer core with plastic type coating designed to activate when wet

  9. Atomic Weight • Weight of an element relative to the standard weight of oxygen (16)

  10. Conversion Factor- • Means of converting K2O (phosphate) and P2O5 (potash) to actual potassium and Phosphorus

  11. Liquid Fertilizer- • Concentrated liquid which must be diluted before application

  12. Micronutrient- • Nutrients needed in small quantities for good plant growth • Examples Fe, Mn, B, Cu, Zn, Mo, Cl Iron, Manganese, Boron, Copper, Zinc, Molybdenum, Cloride

  13. Secondary NutrientsThe Synthesizers Nutrients needed in relatively large amounts Calcium Ca Magnesium Mg Sulfur S

  14. Macronutrient- • Nutrients needed in Large Amounts for good plant growth

  15. Water Soluble- • A dry form of fertilizer used in greenhouses applied through injector systems

  16. Organic Fertilizer- • Naturally-occurring fertilizer-example: bone meal

  17. Inorganic Fertilizer- • Fertilizer created by a chemical process

  18. pH percent Hydrogen • indication of soil acidity. • Smaller pH indicates more acid lever of soil • pH of 6-7 is best
