Right, right.

And when you have soils that are depleted in nutrients and they have nutrients that are also locked up in the clay pH soil structure – The clay soils of northern Arizona are particularly difficult because they're mostly clay-based and they're high alkaline.

And the clay, because of its physical structure, it locks up nutrients from being able to be exchanged with the plants.

And when it's dry, it locks up like concrete, so it doesn't allow nutrients.

Air, porosity, you know, so the plants need oxygen, they need hydrogen, they need different elements from the atmosphere into their root systems.

And water is very difficult to infiltrate.

So when it's dry, the clay is hydrophobic and water doesn't want to absorb.

So how do we do that?
