Liquid Systems Variable Rate Fertilization System

2. What is the Best Option for VR?
Variable rate is efficient
Liquid System’s goal is to be as precise as possible
More precise with liquids
Liquids are the easier to control
In-furrow is most efficient fertilization system

3. What is it? In-Furrow liquid injection system
Fertilizer, Trace Elements, Pesticide, ect.
Pump is built to change rates quickly
Computer controlled
Green Star, Ag Leader, Trimble

4. Set-Up Pump and Control Module attached to air cart or Planter
Pumps liquid from tank to nozzle
Computer will control rate of spray based on GPS position

7. Additional Equipment Additional Pumps Stacker Openers Section Control
Spiker
Additional tanks

8. Disadvantages High set-up cost Have to change application timing
System plus multiple attachments, equipment, soil test
Have to change application timing

9. Summary Effective and efficient system
Has made producers more profitable
Step toward the future
