What Loosens Clay Soil

The best way to loosen and improve clay soil is by adding lots of organic matter. Organic matter consists of the decaying remains of plants and animals. It does a good job of binding clay particles together (better than gypsum). This results in improved drainage and aeration as well as sofer and lighter soil.

How do you make clay soil looser?

In Summary: Improving and loosening clay soil is matter of reducing the percentage of clay in the soil mix. This is done by adding organic material (which becomes silt), and by adding sand. Increasing the percentage of silt and sand in your soil does reduce the percentage of clay.

What breaks down hard clay soil?

Break the soil up with a hoe 5 to 6 inches down into the ground. Use a rotary tiller only if your soil is too compacted to break up with a hoe or spading fork, but use a motorized tiller as a last resort because it can kill worms and other important organisms in the soil.
