        Due to clay's small particle size, the soil is very dense, and it bonds together, which is why some plant roots can't penetrate clay soil. A positive to this, though, is that clay soils are resistant to erosion. A negative is that it takes longer for clay-heavy soil to warm up after a season of cold weather.
