HOW DO WE ARRIVE FROM ANALYSIS TO A CORRECTIVE PROGRAM?
SLIDE 5
Physical Soil Investigations are very Important
SLIDE 6
Scenario of patchy poor tree performance. Identified as nutritional problem. Hence precision soil sampling
SLIDE 7
VARIABLE APPLICATOR TO FIX UNEVEN SOIL CHEMICAL AVAILABILITY AND PH.
SLIDE 8
Scenario 2 where problem was identified as water logging in patches. See poor areas and below the wet areas and advised drainage
SLIDE 9
Complicated and very variable soil due to textural problems calls for sophisticated fertigation. Try to change to a system where the soil does not play a role anymore
SLIDE 10
Variable soil
Balanced nutrient solutions Nutrients fed directly to root system
INJECTING SYSTEM
SLIDE 11
Nutrient balance in the root zone is sometimes more important than the amount of applied fertilizer
SLIDE 12
Change tree performance by switching to hi-tech fertigation
