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
13. Methods of deciding when to apply irrigation water
    

    Tables 13-1 to 13-10 summarize the number and share of irrigated farms using a particular approach to decide when to apply water, by farm size class and by water scheduling method.  more...
