Thinking Outside the Box - Creates Ultimate Outdoor Water Conservation Program
Have you ever thought about Clay Soil and why they lay a clay pad before pouring a slab of concrete for a house foundation? Clay will compact tighter and will not absorb the moisture from the concrete slab while it is curing.. However, a clay base swells and contracts with water from the surrounding soil.
As a growing medium, clay is horrible as it has no oxygen movement and plant roots hate it as there is minimal microbial activity in a clay soil. But since clay will swell and contract with water, it is an excellent water reservoir. So how do we pull water from clay?
If i take a handful of clay and squeeze it , compress it, water will not come out of the clay. But if I lay a paper towel across the clay, I will wick moisture from the clay.
So rather than fight nature lets use natures characteristics to our advantage. If I can add a soil amendment to the soil profile that wicks moisture from clay, and likewise when it rains or is irrigated hydrates the clay, then I have the ultimate water conservation storage method already in the soil. When in times of drought or lack of irrigation, I have plenty of water to keep a landscape alive, I simply need to figure out how to put this concept into practice in the soil profile to give this captured water back to the plants and turf areas.
So we take a hollow sand product, we inject aeration holes into the turf every 3 inches and we now have a soil amendment that makes a vertical column every 3 inches. These columns are directly injected into the clay layer in the soil. So now we have the ability to recharge the clay back full of water when it rains or there is irrigation and we can wick back this stored water from the clay and irrigate the turf roots when there is no rainfall.

Step two, we add a humectant or "AquaGreen" to the soil profile and each day we pull humidity from the air and convert that into FREE water that these same hollow sand columns absorb and recharge this water back to the clay layer.
Third step, we capture rainwater, either by above ground water reservoirs or hidden underground water reservoirs. When it is time to irrigate the landscape rather than use the water from the local water authority, we use the captured rainwater from the last rainfall and this used to keep the landscape thriving.
