What is a predictable consequence of adding sand to clay soils?

When adding sand to clay soils, a predictable consequence is reduced compaction. Clay soils are known for their small particle size and tightly packed structure, which can lead to heavy compaction. The addition of sand, with its larger and more angular particles, helps to create spaces between the soil particles. This increases aeration and drainage, while simultaneously making it harder for the soil to be compacted to the same extent.

Improved aeration and reduced compaction can enhance root growth and microorganism activity, leading to healthier plants. Moreover, this combination helps maintain soil structure, making it easier to work with and improving its overall health for gardening or agricultural purposes. This is particularly important in managing soil health, as compacted soils can lead to poor drainage and root development issues.

The other options, while they may have their own significance in soil management, do not directly relate to the predictable consequence of adding sand to clay soils in the same way as reduced compaction does.
