TURF-TEC 6 and 12 INCH INFILTRATION RINGS

INSTRUCTIONS (IN7-W & IN8-W)

Outline of Uses

The Turf-Tec Infiltration Rings was specifically designed to give infiltration readings directly on site.

It can give you a reading on the rate of water percolation through grass, thatch, mat and soil as

well as directly on bare soil.

Use a heavy jack under the back end of a truck to drive

rings as an alternative to the sledge method

1. Position the Turf-Tec IN6-W driving plates over the IN7 or IN8 - 6 and 12 inch Infiltration

rings so the center bar is in the center of the two plates as shown.

2. Center a suitable wood block across the Turf-Tec IN6-W Steel Driving Plates.

3. Center a jack on the driving plate or wood blocks. Place the top of the jack and the

assembled items vertically under the previously

positioned end of a truck body and apply force to the

ring by means of the jack and truck reaction.

4. Also, tamp near the edges or near the center of the

ring with the rubber mallet, as slight tamping and

vibrations will reduce hang-ups and tilting of the ring.

5. Check the rings with the level, correcting the attitude

of the rings to be vertical, as needed.

Reliability of testing and reducing variables

Saturated test (The most reliable test method)

The most reliable test method for measuring infiltration is called a saturated test. This method is

performed by placing the Turf-Tec Infiltration Rings directly into the soil to be tested and filling the

rings 2-3 times, allowing the water to infiltrate into the soil between fillings. Once the soil is

saturated, you can perform the test.

Moisture Sensing (The quickest test method):

Another reliable method for testing infiltration is to use a Moisture Sensor. Moisture Sensor

readings should be taken at one, two, three and four inch levels of the soil to be tested using a

Turf-Tec Moisture Sensor and the readings should be recorded. The infiltration test can then be

performed on that area. This method should be repeated for each test area. In addition, the next

time the same area is to be tested for infiltration, be sure the Moisture Sensor readings are in the

exact same range before testing. This will eliminate any variables and still produces a reliable

test.

Testing on irrigated areas: Another way to insure a proper infiltration reading on irrigated areas is to use this instrument approximately one hour after irrigation. A visual indication of soil moisture should also be noted by using a Soil Profile Sampler. When using this method, be sure no rainfall has occurred within 48 hours of the test to remove this variable.
PAGE 3
Monitoring Drain fields The Turf-Tec Infiltration Rings can be used to install drain fields. The double ring is much more accurate then just using a single ring or an excavated cavity to test for infiltration. However please check with your local ordinances to see if an ASTM Infiltration test is required, if one is, you may need to use the Turf-Tec 12 and 24 Inch Infiltration Rings. Environmental testing The Turf-Tec Infiltration Rings can be used to perform various types of environmental tests.

Turf-Tec 6 and 12 inch Infiltration Rings Operating Instructions 1. You will need a stop watch; ruler and water supply before testing can begin. (A IN6-W Driving plate and bottle jack or board and dead blow hammer should be used in hard soils.) Also a Moisture Sensor and a Penetrometer reading should be taken if you are comparing infiltration rates over a period of time. 2.

How to get the most out of the Turf-Tec Infiltration Rings on Turfgrass areas Areas can be tested before and after certain management practices have been used. These include aerification, Verti-cutting, and topdressing, along with all the other practices that can change the water infiltration rate. Monitoring Drain fields The Turf-Tec Infiltration Rings can be used to install drain fields. The double ring is much more accurate than just using a single ring or an excavated cavity to test for infiltration.

Turf-Tec 6 and 12 inch Infiltration Rings Operating Instructions 1. You will need: Mariotte Tubes, a stop watch; ruler and water supply before testing can begin. (An IN6-W Driving plate, bottle jack, and a dead blow hammer should be used in hard soils.) If you are comparing infiltration rates over a period of time (or not doing a saturated test), a Moisture Sensor and a Penetrometer reading should be taken as well. 2.

Mariotte Tubes Instructions IN12-W Mariotte Tubes Outline of Instructions for using IN10-W and IN14-W with Mariotte Tubes (Read First) Installation of Tubes: To prevent the Mariotte Tubes from gravitationally forcing water into the rings, be sure they are installed at a proper level in relation to the Turf-Tec Infiltration rings. Each Mariotte tube comes with a calibrated sight glass located on the side.

5.1 This test method is useful for field measurement of the infiltration rate of soils. Infiltration rates have application to such studies as liquid waste disposal, evaluation of potential septic-tank disposal fields, leaching and drainage efficiencies, irrigation requirements, water spreading and recharge, and canal or reservoir leakage, among other applications. 5.

6.4 Liquid Containers: 6.4.1 One 200 L (55 gal.) barrel for the main liquid supply anda length of rubber hose to siphon liquid from the barrel to fill the calibrated head tanks (see 6.9.3). 6.4.2 A 13 L (5 gal.) bucket for initial filling of the Infiltrometers. 6.4.3 Two Turf-Tec IN12-W Mariotte Tubes having a minimum volume capacity of about 3000 mL and 10000 mL (See Notes 1 and 2 and Figures 2 and 2A).

8.1.2 The test requires an area of approximately 3 by 3m (10 by 10 ft.) accessible by a truck. 8.1.3 The test site should be nearly level, or a level surface should be prepared. 8.1.4 The test may be set up in a pit if infiltration rates are desired at depth rather than at the surface. 8.2 Technical Precautions: 8.2.1 For long-term tests, avoid unattended sites where interference with test equipment is possible, such as sites near children or in pastures with livestock.

8.4 Driving Turf-Tec Infiltration Rings with Jacks: 8.4.1 Use a heavy bottle jack under the back end of a truck to drive rings as an alternative to the sledge method (see 8.3). 8.4.2 Position a suitable wood block across the center of the Turf-Tec IN6-W Driving Plates, or wooden driving cap of the ring. Center a jack on the driving plate with a wood block between the driving plate and the jack, or on wood blocks.

8.6.3 Fill both the Turf-Tec Mariotte Tubes with water to the top of the site glass. This is accomplished easiest by attaching a positive flow 1/2” ID x 5/8” OD vinyl tubing from an elevated poly-tank, or water supply, to the top valve located on the top cap of the Mariotte Tube. Next, the top valve is fully opened, as well as opening the petcock, also located on the top cap (Figure 3C and 3D). Proceed filling the Turf-Tec Mariotte tube through the top valve allowing air to escape through the petcock.
PAGE 23
NOTE 6—This most likely will require either a continuing addition of water from graduated cylinders, or the use of the IN12-W Turf-Tec Mariotte Tubes. See figure # 2 and #2A to see the relationship between the height of Mariotte tubes and the height of the constant head of water inside the Turf-Tec Infiltration Rings. A rapid change in temperature may eliminate use of the Mariotte tube. 8.6.10 To see the relationship of the vent tube and water level, follow the below procedure. 8.6.
PAGE 24
8.7.1 Record the ground temperature at a depth of about 300 mm (12 in.), or at the mid-depth of the test zone. 8.7.2 To determine and record the volume of liquid that is added, maintain a constant head in the inner ring and annular space during each timing interval by measuring and reading the site glass the change in elevation of liquid level in the Mariotte tube. After recording how much water was been siphoned from the Mariotte tube, move the rubber water height marker to the new water level position.

A1R = internal area of inner ring, cm2Δt = time interval, h 9.1.2 For the annular space between rings, calculate as follows: VA = ΔVA /(AA · Δt) Where: VA = annular space incremental infiltration velocity, cm/h ΔVA = volume of liquid used during time interval to maintain constant head in the annular space between the rings, cm3 AA = area of annular space between the rings, cm2 Δt = time interval, h 10. Report 10.1 Report the following information in the report, field records, or both: 10.1.

10.3 See Appendix X1 for information on the determination of the moisture pattern. 11. Precision and Bias 11.1 No statement on precision and bias can be made due to the variability in soils tested and in the types of liquids that might be used in this test method. Because of the many factors related to the soils, as well as the liquids that may affect the results, the recorded infiltration rate should be considered only as an index value.
