Abstract
We have developed a way to disperse air as micro-bubbles in water, without or with nutrients added to the
water, at any depth in soil above the water table using a cylinder structure of fiber media. The cylinder
structure is a modified, over-the-counter consumer paper product, Bounty brand paper towels. The
modification involves placing a tightly fitting polycarbonate tube of 44” length inside the central cardboard
tube of a standard 6” diameter x 11” paper towel roll. This central tube stabilizes the roll from collapse when
the structure is placed into soil. For all of our tests holes were made using a posthole digger where the
diameter of the hole was 8-in. and the depth was varied from 1-3-ft. For transport of aerified water from inside
the cylinder into the soil it is imperative that soil be tightly compacted to the exterior of the cylinder structure
except for the cylinder top. In all of our tests soil from the hole was tightly compacted around the cylinder but
leaving the top of the cylinder exposed. Without the plastic tube inside the roll the pressures in the soil will
collapse the cylinder shape impairing the transfer of aerified water across the fiber cylinder-soil boundary. For
these tests the top of the roll must be uncovered to allow the essential air-water exchange process. Tests
have been done in compacted clay soil, as well as compacted sandy soil.
It is possible to establish the rate at which aerified water, without or with nutrients present, disperses from the
cylinder into the soil as a function of depth. One can add known volumes of water to the top of the cylinder in
the soil at a rate which will match the rate that the soil evacuates the aerified water from the cylinder. In this
way we could determine the rate of adsorption of water into soil. Let’s consider some examples. For a highly
compacted sandy soil in Fair Lawn, NJ the rate of transport of water changed as a function of depth. The rate
was 40,000 cc per hour in the case where the top of the cylinder was level with the soil surface. This translates
into the cylinder filling and emptying of water every two minutes (the void space within the cylinder is 1750 cc).
At 2-ft. depth and 3-ft. depth the rate is 20,000 cc per hour and 10,000 cc per hour, respectively. In clay soil at
2-ft. depth the rate slows to 1750 cc per hour. However, over time the rate increases. The volume to fill the
cylinder, 1750 cc of water, is absorbed into the soil in 2-8 minutes as the clay soil porosity improves, usually in 2-
weeks time. One of the most important tests was done in a water retention or recharge basin in Edison, NJ
owned by the New Jersey Dept. of Transportation. In this basin the modified-fiber-cylinder was placed 2-ft.
below the surface in two locations. In the region of the basin with a lower water table 1750 cc of nutrients in
water adsorbed into the soil in 3-5-minutes compared to a time of 40-minutes just weeks earlier. Deep soil
compaction restoration appears to be a consistent consequence of pulsing aerified water using fiber structures
where rock-hard clay soils have been tested.

7. PROJECT PORTFOLIO DOCUMENT ANTONY OCHIENG ODHIAMBO
EXPLANATORY NOTES:
The breather tubes were symmetrically-placed in a grid at equidistant points, for two main reasons;
The grid areas are a demarcation of the points at which preliminary readings were taken and the same
points shall be used in making further comparative readings.
The grid presents a convenient way of tracing the breather tubes in the “maze” of a garden.
The grids are frameworks which capture the points where the breather tubes’ pre-installation readings were
made. The distance between the grid coordinates is 2 ½ Meters and is indicated in the gap between the two
sets of grids in the northern direction with a discontinuous green line.
The alongside (lone) breather tube was installed to serve as a control test, and so subsequent
readings around it would be used to derive comparisons and to augment the study findings. It is a lone
tube and so it would be expected to function in isolation.
The following are the Breather tubes’ pre-installation penetrometer readings that were made on 23rd
June 2012.

I am using 2 weeks as my threshold for making comparative readings. This is because currently, rains are
flooding the garden and other areas, and so a relatively and reasonably dry ground would be ideal to take the
readings. The floods would only skew the readings because the soil would somehow be “inconveniently
lubricated”. This “lubrication” would be unwarranted and, needless to say, would not be a true reflection of
the depth of penetration that the soil compaction tester would go.

Peculiarities observed:
At the exterior surface of the breather tubes, there were small ants gathering around. I would not tell whether
this is because may be the adhesive used in assembling the contraption (breather tube) which may be sugar-
based and which would be attracting them?
Methodology.
I dug holes of almost the exact diameter with a sharp pointed knife, and placed the breather tubes in those
holes, to a distance of 4 cm above the ground. The holes were tightly-fitting, so that the tubes would fit inside.
I tightly compacted soil around the breather tubes to enhance a greater surface tension, which is a requisite
condition in this experimentation.
The breather tubes were equidistantly placed in the grids and this proved to be very efficient in locating them
among the maize and bean plantation. I would then use a 500 ml cup to water the breather tubes. I would pour
water twice into each tube, distributed over one hour, which makes it one liter.
Rain water would also pour into the tubes, which I meticulously collected using a cylinder-shaped mineral
water plastic bottle with its top area employed as a funnel. The rain gauge was placed firmly in an open area to
avoid any foreign water drops from getting into the gauge. I also secured the bottle at a convenient depth, of
about 6 cm, to avoid it being swayed by wind or vigorous rainfall. I usually water the tubes in the evening from
6:30 p.m to around 7:30 p.m daily, except for days when rain falls. When rain falls, I usually collect the rain
water the morning after since it usually rains late in the night too. That would form a complete cycle of a day
and I would consider that to be the rainfall amount of that day.

Questions:
Q1. I wish to ask, since scenario A in Fig. 1 above is the most appropriate, because the water enters the breather
tube from the top, and thus runs down into the deeper areas, and pulses air towards the external surface of
the soil due to surface tension which is present both in the inner part of the tube and which is greater in the
surrounding soil, would it be okay if rains hit the area surrounding the exterior of the breather tube as
demonstrated above, since most of the rain would just percolate at the breather tube exterior and not much
would enter directly into the tubes-which would not be so effective in pulsing air to the surrounding soil
presumably because there is not much water in the inner part of the breather tube to be pulsed to the outside
in form of air bubbles-. Is this situation (B) equally effectual?
Q2. If there is a shift in watering patterns and frequency, let’s say, in this instance I usually water the tubes
once a day, in the evening, because I am not always available in the mornings and daytime, due to other
engagements. Would it be appropriate if I changed from watering them in the evening to maybe daytime and
let’s say twice or thrice a day at some point if there is a relaxation of my busy schedule?
