Irrigation and Crop Yield
Best barley yield: 16 irrigation units
Too little water → plants cannot grow well
Too much water → lower yield
Too much water problems
Soil waterlogged
Roots get less oxygen
Nutrients washed away
Salt builds up in soil
Salinisation
Causes
Removing native plants
More water stays in soil
Water evaporates
Salt left behind in soil
Prevention
Trickle drip irrigation
Small amounts of water
Water goes directly to roots
Less evaporation
Less salt accumulation
