Turf grass Management: 1 Grass Fundamentals
Grass Structure
ROOTS
Tough
Shallow (affects irrigation)
Branched (grab more nutrients)
Everything below ground
SHOOTS
Everything above ground
Stem
leaves
Blade (upper part)
Sheath (lower part)
flowers / seedheads
Subapical growth (grows from the base)
Buds
regenerate new plants
Crown
if alive, the plant remains alive even when cut.
GROWTH PATTERN
Tillers (shoots that develop into new plant)
Stolon (above ground stem)
Rhizome (below ground stem
FOOD PRODUCTION
Photosynthesis
Respiration
Chlorophyll
Transpiration
Stomata
BASIC NEEDS
Sunlight
Water
Nutrients
macronutrients
C, H, O, N, P, K, S, Ca, Mg
micronutrients
Soil
composition
Sand
water and nutrients penetrate easily but can Leach easily.
Clay
Hold water and nutrients easily but may be too dense.
Breathable space
Silt / Loam
Ideal soil with the right balance
Living organisms + micro organisms
digest organic matter and prevents Thatch
pH
Turfgrass grows best between 6.0 to 6.5
Clay is too acidic
Sand is too alkaline
TURFGRASS SELECTION
aesthetics
playability
physical characteristics
geographic location
Usage
Greens (grass that can be cut short)
Fairways (color and density)
Roughs (low maintenance)
Teeing areas (resist foot traffic)
resistance for pests and disease
Cool Season Grasses (60 -75
Bentgrass
Bluegrass
Perennial Ryegrass
Fescues
Warm season grasses
Bermuda grass
Cultivars
Modified grasses
