467. Austin, Colorado, irrigation, 1949-1952

Final irrigation report on comparison of sprinkler and furrow irrigation on apples at Western Slope

Branch Station. by

W. E. Code

Associate Irrigation Engineer

Work on this project bean in 1949 and ended in 1952. The object was that of makint7 comparisons between trees irriated by the ordinary furrow method and sprinkling. The differences

would be determined by shoot growth, fruit size, color and pro-duction as reported by F. M. Green, Station Superintendent. This report deals only with the irrigation and soil moisture phases.

Originally the plot of

8

acres was all furrow irrigated.

In the spring of

1949

the upper

4

acres was prepared for sprinkler irrigation by smoothing out all furrow marks and installing a

pumping plant along a clay pipe line on the north side. For that first year an east and west ditch was used to distribute water to the

4

acre furrow plot. For the remainder of the time 8-inch gated pipe was used for this purpose.

The sprinkler system consisted of 2 laterals of 3-inch and 2-inch pipe and a short 3-inch header pipe. Each lateral was equipped with 22 low-angle, orchard type sprinkler heads with 5/32-inch nozzles. Water at 32 pounds pressure was provided by a 2-inch centrifugal pump driveri)y a

5

h.p. single-phase motor. The discharp;e of the pump under operating conditions was

measured at 154 gallons per minute providing a s4ross application rate of 0.53 inch per hour. In the first year of operation, smaller nozzles were useu Which provided an application rate of

of 0.40 inch per hour. Observations on moisture penetrations indicated that a 12-hour run at this rate was inadequate and therefore the rate was increased for the following years. Trash was prevented from entering the system by a vertical screen of 1/8-inch hardware cloth. The effective dimensions of this screen

provided an area of

8

_{square feet. Since surplus water passed on} out of the pump pit, much trash was thus carried away and the screen required little attention. The only real trouble with screening came when the water was carrying "moss" at which time frequent cleanin7 was necessary.

Sets for the furrow plot were made to operate for 24 hours. The amount of water turned into each furrow varied from

8

to 20 gallons per minute according to the flow available. Sometimes wlth an adequate supply, only 2 sets were required but on a number of occasions with a short supply

3

sets had to be made. Usunlly with a good flow in the furrows, more water was absorbed. The gated pipe provided good water control but not without attention as to clogging of openings. Tree leaves at the end of the season were particularly bothersome in this regard.

During the first season water was measured through a 6-inch Parshall flume located in the entrance ditch to the Station. Two more such flumes were provided the second year which greatly

improved operating conditions and accuracy. Run off was measured by a 3-inch Parshall flume.

In order to evaluate the irriq:ation, explorations were made with a soil moisture probe or a soil auger. ::_oisture determina-tions were made, except in a few instances, before and after

irrigations. The method used was that of judging the appearance and feel of the soil brought up by the auger. Explorations were usually from

4 to

5 feet deep but in many instances this was not possible before irrigation because of the many rocks encountered. Better luck was experienced after irri ation when the soil was soft.

Moisture penetration under the sprinkler the first season seldom exceeded 30 inches. This wps considered inadequate because many tree roots are below this level. In the following 3 seasons moisture penetration was almost always in excess of 36 inches. Beyond this depth moisture conditions were always found favorable before irrigation. Depth of penetration varied according to the extent of drying out of the upper part of the soil profile.

Except in a very few cases uniformity of distribution was found to be entirely satisfactory.

Evaluation of moisture conditions in the furrow plot was quite difficult. Furrows were from 4 to 5 feet apart and generally

moisture did not spread laterally sufficiently to meet between furrows. Further, moisture beneath the furrows penetrated beyond the reach of a

5

foot auger.

The amount of water applied in inches of depth for each plot in each irrigation is giv en in the following table.

It will be noticed that nearly the same amount of water was applied at each irrigation with the sprinkler. This is far from true with the furrow irrigation. Each spring the furrows were opened with a disc furrower leavin the top soil loose and hilhly absorbent. At least once during the season they were cleaned with a ditcher point. Frecuently the cleaning process left a polished surface over which the wnter ran rapidly and with very little depth. At such times absorption wns the least and when weeds were present and depth of flow increased, the absorption was greater.

A curious trend is to be noted in absorptive characteristics in the furrow plot. In each succeeding ye-jr the average absorption

per irric;ntion was pro-Tessively less. The reason for this is not readily apparent. The first seasons high application was caused largely by excessive flows. All the water not needed by the sprinkler had to be used in the furrows because of lack of measuring devices. This was corrected in the following years. The hardening up of the soil in the furrows with no deep cultiva-tion may be in part responsible for this trend. The applicacultiva-tion rate under the sprinkler was well under the maximum absorption rate and the soil at the end of the last season was in excellent condition.

The experience of 4 years of working with the Iwo methods of irrigating brought out some important points about both. Each showed some shortcomings and advantages.

The sprinkler is warerable to a power failure. Should such a failure occur at night and not discovered, the irri7ator would be uncertain as to how much time had been lost. Under conditions existing at the Station, no particular trouble was experienced with noz7le plugging except when the screen became damaged. This

damage occurred when the water wns carrying "moss" which could quickly clog it thus building up a pressure on one side that

6he,./d 6Q resulted in its being torn from its fastenings. Asers

C f II:, /4/ Je ..=: / go 6/1/4

stand-vertical-1y automatically. They need to be set plumb and frequently, they tip Slightly after the water is turned in.

Long, sweet clover stems adjacent to a sprinkler, if not removed, sometimes catch in the turning mechanism and stop rotation.

Moving pipe at 12-hour intervals did not fit very well into the work schedule and in the last year this was changed to 10 and

14 hours. Moving re7uired from 20 to 25 minutes with 2 men

working. Freezin weather on 2 of the late irrigations resulted in a heavy ice accumulation on the trees. A decidedly better uniformity of water application was obtained under the sprinkler. The much denser cover crop was ample evidence of this. One of the most frequently heard criticisms of sprinkling is that of

cost of operation. In this particular case the average power requirement was 77 Kilowatt hours per acre per irrigation. No repairs were necessary and there were no other costs.

If the time required to make a set with gated pipe and moving sprinkler pipe is ignored, more time was spent with the gated pipe in making admustments and clearing trash than with the sprinkler. Similar adjustments of course are also required with furrow openings '1J1 a ditch bank. Unsteady flow in the supply on a number of occasions made it necessary to either cut back or increase the number of openings. With no trash to contend with, control of the water to each furrow was easily maintained.

The plot under the sprinkler received a 7ross application of from 30 to 36 inches of moisture annually. It was felt that no water was lost by deep percolation. If an estimate of loss by evaporation from the streams in the air and wetted surface

be taken at 25 percent, then the water used by the trees and cover crop was from 23 to 27 inches annually. From the superficial

appearance of the crop, this amount of moisture seemed adequate.

MEMORANDUM

Date January 10, 1952 TO: All Instructors in civil engineering _building FROM: D. F. Peterson, Jr,

Please rend to all classes held in the civil engineer-ing buildengineer-ing:

fTSmoking regulations in the civil engineering building are as follows:

1, No smoking in any class room at any time including laboratory classes held in class rooms, 20 Smoking permitted only in the

halls and in the student lounge, and only with the understanding that WAJdvnts place their cigarette butts in the ash trays providedL

As you are aware the civil engineering build-ing is a long way from bebuild-ing fireproof. In the last two years at least two fires have started in this building _{Except for vigilence of the staff} members the building would surely have burned, We simply cannot take the risk of having a fire and for this reason we have set up certain rules for smoking in the building which we think elimi-nate most of the risk and at the same time do not place an unreasonable hardship on those who smoke, We ure your co-operation in observing these rules

These rules have been grossly violnted so far this quarter _{Continuing violation will reouire} that all permission for students to smoke in the building be denied."

Civil engineering instructors are requested to assist in enforeinc; these rules.
