Slide1Objective 24.03• Demonstrate the application of various types of fertilizers
Slide2Application Procedures• Banding • Sidedressing • Topdressing • Perforating • Broadcasting • Foliar spraying • Fertigation
Slide3Banding• Placing a band of fertilizer about two inches to the sides and about two inches below seed depth. • DO NOT place below the seeds because fertilizer will burn the roots.
Slide4Sidedressing• Placing a band of fertilizer near the soil surface and to the sides after seedlings emerge from the soil.
Slide5Topdressing• Mixing fertilizer uniformly into the top one to two inches of growing media around the plant.
Slide6Perforating• Placing fertilizer in 12”-18” holes drilled 18” to 24” around the canopy drip line of fruit trees. Cover the holes and fertilizer slowly dissolves.
Slide7Broadcasting• Spreading fertilizer to cover the entire production area
Slide8Foliar Spraying• Spraying micronutrients in a solution directly on plant leaves. • Quickly corrects nutrient deficiencies • Fertilizer concentration should not be too high or leaf burning will occur.
Slide9Fertigation• Incorporating water-soluble fertilizer into the irrigation system of greenhouse and nursery crops. • Concentrated solutions usually pass through proportioners or injectors to dilute to the correct ratio. – Venturi-type – Positive-displacement
Slide10Venturi-type• Simple and inexpensive • less accurate • depends on water pressure in the hose and in the smaller tube to proportion • Example: Hozon
Slide11Positive-displacement• More expensive • very accurate • physically inject and mix specific amounts of concentrated solution and water • Examples: commander proportioners, and Smith injectors
Slide12Rules for applying fertilizers• Method used should be practical, effective and cost efficient • Method used affects nutrient availability for plant use • Fertilizer must be dissolved and reach plant roots
