Symptoms
Nitrogen is the most common nutrient deficiency observed in turfgrass.
Nitrogen-deficient turfgrass turns yellow and has reduced vigor.
Iron deficiency is common in alkaline soils. Symptoms of iron deficient
turf include yellow or bleached spots, which give leaf blades a mottled
appearance.
Potassium deficiency causes leaves to turn yellow and brown on margins.
Phosphorus deficiencies cause leaves to turn purple, creating dark
areas in turf.
Prevention and management
Follow recommended fertilization
rates for your turfgrass species. Turfgrass grows best in soils
that are not too acidic or alkaline and with a pH in the range
of 6 to 7. A professional soil
analysis may be necessary to determine which nutrients are
lacking in your soil and can provide you with information about
what to add to your soil to maintain an ideal soil pH. |
