TREATMENT COMMENCED

Location: Grass Nursery.
Test Area: Marked T1
Control: Marked C1

Soil is Hydrophobic and grass growth is poor.
Dosage: Double suggested dosage applied.

11 NOVEMBER 2003


5 Millimeters of rain fell on 10 November 2003. Grass is getting green and general appearance of grass is much improved.
No other noticeable differences between Test and Control.

3 DECEMBER 2003


Grass in Test area is noticeably greener than in Control area.

Very hot temperature without any rainfall for over a week is causing grass to go yellow in surrounding areas.

17 DECEMBER 2003


No rain for 3 weeks now and grass is going yellow. Grass in Test area is however still noticeably greener than grass in Control area.

17 DECEMBER 2003 SOIL SAMPLE CONTROL 1


Soil sample extracted from Control 1 and Test 1 do not indicate any noticeable difference.

17 DECEMBER 2003 SOIL SAMPLE TEST 1


Soil sample extracted from Control 1 and Test 1 do not indicate any noticeable difference, apart from the fact that the top layer of sand in the Test area is thicker than in the Control area.

6 JANUARY 2004 – TEST 1


Grass in Test 1 area noticeably greener and lusher than in Control 1 area.

Observation made by Mr. Johnny Hammond, the Green Keeper that the grass in the Test area is in better condition than in the Control area and that the grass has knitted better as well. This is encouraging as this result was achieved, despite the fact that the Test area gets less water due to the location of the sprinkler systems and the prevailing wind direction. See next photos taken close up of Test 1 and Control 1 areas respectively.


Close up photo taken of Test 1 area.
Grass in very good condition, closely knitted and green.
Grass is greener in Test 1 area due to improved water retention capability of soil.

Note: Average rainfall thus far this season has been lower than in previous years and the drought conditions are the worst experienced in the past 88 years.


Close up photo taken of Control 1 area.
Grass not nearly as green as in fact yellow in appearance. Grass also not as closely knitted as in Test 1 area above.

13 JANUARY 2004


Grass is looking good. T1 trial area has produced positive results despite the fact that this particular area receives less water, as a result of location of sprinkler system and prevailing wind direction.

The following results have been achieved:
- Improved water permeation of soil
- Increased water retention capability of soil
- Improved growth resulting in greener, lusher and closer knit   greens.

1 FEBRUARY 2004 – SOIL ANALYSIS

KYALAMI COUNTRY CLUB - SOIL ANALYSIS REPORT (SOIL SAMPLE 01/02/2004)
Analysis Abb. Control Test % Change Comments
Phosphorus - mg/kg P 10.9000 15.4000 41.28% Positive change as P is important from an energy transfer point of view as part of Adenosine Triphosphate. (ATP)
Potassium - mg/kg K 37.0000 43.0000 16.22% An adequate supply of Potassium and Magnesium in the grass is essential in order to produce and replenish the carbohydrate supply necessary for vegetative growing points such as the roots and new grass shoots. Essential for performance of photosynthesis, carbohydrate translocation and protein synthesis.
Potassium - me/100g K 0.0946 0.1100 16.22%
Calcium - mg/kg Ca 289.0000 386.0000 33.56% Increase in Calcium due to increase in soil biology i.e. bacteria, fungi and other micronutrients. Fungi prevent leaching of Calcium into soil. Ratio of Ca to Mg in Control is 4.4:1 whereas it is 4.8:1 in Test. This represents a 10% reduction in soil compaction.
Calcium - me/100g Ca 1.4421 1.9261 33.56%
Magnesium - mg/kg Mg 66.0000 80.0000 21.21% An adequate supply of Magnesium and Potassium in the grass is essential in order to produce and replenish the carbohydrate supply necessary for vegetative growing points such as roots and new grass shoots. Increase in Magnesium due to increase in soil biology i.e. bacteria, fungi and other micronutrients. Fungi prevent leaching of Calcium into soil. Magnesium deficiency is one of the greatest limiting factors for plant growth. Ratio of Ca to Mg in Control is 4.4:1 whereas it is 4.8:1 in Test. This represents a 10% reduction in soil compaction.
Magnesium - me/100g Mg 0.5432 0.6584 21.21%
Sodium - mg/kg Na 34.0000 28.0000 -17.65% Open-All® has reduced the level of sodium in the soil. Sodium can be harmful to the grass as it clogs and burns the root system.
Sodium - me/100g Na 0.1479 0.1218 -17.65%
pH pH 7.2400 7.0700 -2.35% pH Decreased from "Slightly Alkaline" to "Very Slightly Alkaline". pH Should ideally range between 6.5 and 6.8. pH of this soil therefore needs to be reduced even further. The lower the soil's pH is, the greater the depletion of Nitrogen. Without biology, pH is the sole arbiter of what is available to plant roots. With organisms however, plant nutrition is no longer ruled by chemistry alone.

17 APRIL 2004 - ROOT ANALYSIS

17 APRIL 2004 ROOT COMPARATIVES


Top left photograph of soil samples reflect varying thickness of soil layers in Control area (Left) and Test area (Right). Soil structures exactly the same from an appearance point of view.

Top right photograph reflects the roots after having had the soil washed off. Close-up photograph on the left. The roots of the grass from Test area measure 16cm in length whereas the Control roots measure 9cm in length. The roots in the Test area therefore penetrated the soil 78% deeper than the Control roots, enabling the roots in the Test area to take in additional nutrients and water. This will also enable the grass to withstand harsher conditions and the grass will remain greener for longer during the winter months.




Second root sample taken. Similar root quality and length observed.

Mr. John Hammond, the Green Keeper at Kyalami Country Club is most impressed with the very noticeable difference in root growth.

He stated that the benefits to the grass will be significant in every respect, ranging from:
• greener, closer knitted greens
• improved grass growth and recovery
• improved absorption of nutrients and water
• improved resilience during stress conditions, dry season and in winter
• reduced soil compaction, etc.
