BRAE 340 Exam 3 Questions and Answers
100% Solved
Hand Move sprinkler Constraints Correct Answ_the strategy is to match the SMD to the
application in 11 or 23 hours:
-this gives us time to move the sprinklers each day
-11 hours is 2 moves per day with 1 hour per move
-23 hours is 1move per day with an hour per move
Center Pivot Constraints Correct Answ_-constant flow rate
-strategy to determine the number of hours/week and/or per rotation.
DU Correct Answ_measure of how uniformly the water is distributed
=Dmin/Dave
Excess water Correct Answ_suface runoff and deep percolation
Basic ideas of irrigation Correct Answ_-good uniformity
, -correct depth
-minimize losses
Scheduling questions Correct Answ_When to irrigate?
How much to apply?
Techniques for When Correct Answ_indicator threshold
-SMD vs. Time (checkbook)
-SMC vs Time (soil sensors)
-SMT vs Time
Techniques for how much Correct Answ_Weather based approach
-target depth (CIMIS)
-PI losses
-DU
By-feel Method
-soil samples at different depths
-several locations in the field
