  1. Hort I:Obj. 24.03 Demonstrate the application of various types of fertilizers.

  2. A. General Rules • Method used should be practical, effective & cost efficient. • Method used affects nutrient availability for plant use. • Fertilizer must be dissolved & reach plant roots.

  3. B. Banding • Placing a band of fertilizer about 2” to the sides & about 2” below seed depth. Do NOT place below seeds because fertilizer will burn roots.

  4. C. Sidedressing • Placing a band of fertilizer near the soil surface & to the sides after seedling emerge from soil

  5. D. Topdressing • Mixing fertilizer uniformly into the top 1-2” of growing media around the plant

  6. E. Perforating • Placing fertilizer in 12-18” holes drilled 18” to 24” around the canopy drip line of fruit trees. Cover the holes & the fertilizer slowly dissolves.

  7. F. Broadcasting • Spreading fertilizer to cover the entire production area.

  8. G. Fertigation • Incorporating water-soluble fertilizer into the irrigation system of greenhouse & nursery crops. Concentrated solutions usually pass thru proportioners or injectors to dilute to the correct ratio.

  9. Types of proportioners • Venturi-type: simple & inexpensive, less accurate. Ex. Hozon – depends on water pressure in the hose & in the smaller tube to proportion.

  10. b. Positive displacement: more expensive, very accurate. Ex. Commander proportioner & Smith injectors. • Physically inject & mix specific amounts of concentrated solution & water.

  11. H. Foliar spraying • Spraying micronutrients in a solution directly on plant leaves. It is used to quickly correct nutrient deficiencies, but the fertilizer concentration should not be too high or leaf burn will occur.
