Placement of IRROMETERS in

Furrow Irrigation

Place IRROMETERS approximately 2/3 of the way down the

run with tips angled slightly towards the furrow. In tree crops

the IRROMETERS are generally placed on the side of the tree

which gets the afternoon sun. In row crops they would

normally be placed in the row. Since lateral movement of

water varies widely with different soils, the closer the tip is

located to the side of the furrow, the more representative the

results will be.

Placement of IRROMETERS in

Flood or Border Irrigation

In flood or border method of irrigation, IRROMETERS are

normally placed approximately 2/3 of the way down the run as

this generally is the point most critical for adequate

penetration. The general rule of locating at the drip line of the

tree in tree crops or in the row for row crops, is best. It is also

best to order IRROMETERS at least 6" longer than desired for

placement so that the gauges can be set higher, above the

water level when irrigating. In some cases it has proved

beneficial to place IRROMETERS on the border itself, at an

angle, so that the tips are located in the root zone of field

crops.

Placement of IRROMETERS in

Sprinkler Irrigation

In sprinkler irrigation IRROMETERS are normally located on

the side of the tree where the afternoon sun shines. Again,

placement should be at the drip line of the tree. Special care

should be exercised in tree crops to insure that limbs or heavy

foliage do not obstruct the sprinkler pattern to the

IRROMETER location or that they are not located beyond the

normal pattern of the sprinkler. In row crops IRROMETERS

are located in the row.

Placement of IRROMETERS in Drip

Irrigation

In drip irrigation, IRROMETERS are normally located on the

sunny side of the tree and essentially at the drip line of the

tree. IRROMETERS are generally placed 12"-18" away from

the emitter (24"-36" from the micro sprinkler or spray) to

insure that they are in the wetted area. In newly planted trees,

the shallow IRROMETERS should be placed in root ball of the

tree regardless of emitter location. In row crops the

IRROMETERS should be placed in the row. Additional

IRROMETERS may be used to measure water movement

away from the emitter but controlling IRROMETERS should

be placed in representative locations 12" to 18" from the water

source and in the root mass area.
