Healthier Plants

• Optimum combination of Air and Water being applied to the root zone.

• Roots are not drowning.• Ag – Higher yields per acre• Landscape – Larger, healthier plants

22

Fertigation• Applies fertilizer

uniformally to the plant’s root zone throughout the growing season.

• Minimizes fertilizer runoff

23

9. Do you get many customer support calls from homeowners?• Homeowners – 25% of calls• Professionals – 75% of calls• Make recommendations to homeowners that they

hire a Licensed Professional Landscape Contractor
