Western Irrigated Agriculture: Tables

All tables summarize data by farm size and State

1. Total irrigation values, all irrigated farms
2. Average irrigation statistics (per farm)
3. Average irrigation statistics by water source (per farm)
4. Irrigation wells and pumping costs by energy source
5. Average irrigation maintenance and repair costs (per acre)
6. Gravity irrigation statistics by system type
7. Pressure/sprinkler or sub-irrigation statistics by system type
8. Gravity irrigation by system type and water-management practice
9. Gravity water-management statistics by management practice
10. Laser-leveled irrigation statistics
11. Water-conserving, higher-efficiency pressure irrigation statistics
12. Water-conserving, higher-efficiency gravity irrigation statistics
    

    Tables 12-1 to 12-9 summarize number of farms and gravity-irrigated acres for alternative definitions of more water-conserving gravity irrigation technologies, by farm size class.  more...
