What is the role of soil properties in irrigation design?
soil properties in irrigation design
Soil Texture: Influences water-holding capacity and infiltration rates. Sandy soils drain quickly but hold less water, while clayey soils retain more water but drain slowly.
Soil Structure: Affects water movement; well-structured soils improve infiltration and reduce runoff.
Soil Moisture Holding Capacity: Determines irrigation frequency; higher capacity means less frequent irrigation.
Soil Permeability: Affects how quickly water moves through soil; high permeability reduces runoff, low permeability can cause waterlogging.
Soil Bulk Density: Higher density indicates compaction, affecting water infiltration and root growth.
Soil Depth: Affects root zone and water storage; shallow soils require more frequent irrigation.
Soil Drainage: Essential to prevent waterlogging; well-drained soils need less drainage.
