Application Guidelines

Directions For Existing Lawns: The best method is to aerate lawn prior to application, and rake up the plugs. Using a bottom dump spreader, apply WATER-LOK approximately 1/8" thick over entire area or1.2 kilos per square meter of surface. For non-aerated lawns, apply WATER-LOK as a top dressing approximately 1/16" to 1/8" thick. Water thoroughly for first two weeks, then reduce watering as needed.

Directions for Building New Lawns: Premix Water-Lok with mixture of soil and sand for lawns and fairways at a ratio of 1 kilo. of WATER-LOK to 5 kilos of soil. Apply mix to depth of 4 to 6 inches. An 80/20 mix with sand reduces percolation rate from 29 in./hour to 5.92 in./hour. A 90/10 mix reduces percolation rate from 29 in./hour to 11.64 in./hour. It is highly recommended that, if possible, a layer of Water-Lok be placed between the surface soil and the base soil to create a semi permeable barrier between the two. This layer should be a minimum of half an inch thick.

Directions For Potting Soil: Mix 1 part WATER-LOK to 5 parts soil. Plant as usual. For existing plants, spread 1/8" WATER-LOK and scratch into surface of soil and water thoroughly. Reduce future watering as needed to avoid over watering.

Directions for Nurseries using flood irrigation sandy soil: Excavate planting site. Place 1 kilo of Water-Lok in bottom of hole. Lightly mix with soil in bottom of hole. Set plant on top. Fill around root with Water-Lok and soil mix from 1 to 3 to 1 to 5 mix depending on soil conditions. Water planting. Continue to water at 50 % of schedule used in the past.

Directions For Trees and Shrubs:

1. Date Palms and Washingtonia Palm
2. Shrubs and Citrus 5 gal. to 15 gal.
3. Other tree (ornamental and shade)
4. Seasonal and ground cover

1. Date Palm and Washingtonia Palms installation

A. Trench (square) 1 meter away from tree.
-12 inches wide by 30 inches deep.
B. Water-Lok and organic matter
-Mix 70 kilo of Water-Lok with 130 Kilo of organic matter pour evenly in trench.
-Apply soil on top leaving a 4 inch well for water.
C. Watering -apply 25 gal of water into well, let it recede then apply 25 ga.l a second time and again a third time.

2. Shrubs and Citrus -5 gal to 15 gal

A. Trench ( circular) -18 inch -24 inch away from shrubs, 6 inches wide by 20 inches deep.
B. Water-Lok and organic matter
-Mix 6 kilo to 10 kilo of Water-Lok with 15 to 30 kilos of organic matter
Apply soil in trench leaving a 4 inch well for the water.
c. Watering- apply from 10 gal. to 20 gal. of water into well. Let it recede and apply again.

3. Other Ornamental and Shade Trees (Large)

A. Trench (see Palms)
B. Water-Lok and organic material.
-Mix 45 kilos of Water-Lok with 90 kilos of organic matter and pour into trench.
-Leave a 4 inch well for the water.
C. Watering- apply 25 gal of water into well. Let it recede and apply two more times.

4. Seasonal and Ground Covers

A. Apply Water-Lok by spreading product at the rate of 2.2 kilos per square meter over area before you plant or in planted areas, just spread Water-Lok on top of area.
B. In areas you are going to plant, using a small tiller to go over the area. Use criss-cross pattern 3 inches deep then plant.
C. After planting, water thoroughly.

Check your irrigation system and reduce timing according to season.

Special Note:

1. Get a quart jar from the supermarket with a lid or use any jar with a large mouth.
2. Fill the jar half full of soil
3. Wet the soil to a mud consistency and tap the jar to settle the soil.
4. Mark the level of soil on the jar with a marking pen or whiteout
5. If you have some calgon put a teaspoon full in the jar
6. Add water to the top of the jar and shake the soil water mix till the soil is all mixed up in the water.
7. Put the jar on a table and let the soil settle out for 40 seconds, mark the level of soil on the jar. This is sand portion in the soil.
8. Wait 6 hours and mark the level of the soil in the jar. The difference between the bottom mark, which is the sand,  and the  second mark up is the silt portion of the soil. The total sand plus silt is the distance from the bottom of the jar to the second mark.
9. Calculate the percent sand, silt and clay by measuring the depth of the soil by measuring the distance from the bottom to the first mark up in inches which is the sand fraction, the distance from the first mark up to the second mark up which is the silt fraction and the distance from the bottom to the third mark up from the bottom which is the sand plus silt plus clay fraction. . Sometimes, when all the sand silt and clay has settled, the height of the soil is higher than when you marked the jar  after making a mud solution. This can only be determined by letting the jar sit for several days. If you have the time to do this , then a more accurate calculation of % sand silt and clay can be determined based on this new measured total height. Also, the percent sand, silt, and clay is a volume percentage. The soil triangle  and table below for soil classification is in percent by weight.  You need to correct this problem by converting from percent volume to percent weight by multiplying the percentage of sand by 1.19, the percentage of silt by 0.87 and the percentage of clay by 0.94. These numbers are the weight ratio's of bulk density compared to average bulk density of the material.
10. The percent sand is the depth of the sand divided by the depth of the total soil
11. The percent silt is the depth of the silt divided by the depth of the total soil
12. The percent clay is 100 minus the percent sand plus silt.
