In this manner, what are cinders in soil?

Cinders are extrusive igneous rocks. Cinders are similar to pumice, which has so many cavities that its low density of 0.641g/cm^3 allows it to float in water. Cinder is typically brown, black, or red depending on its chemical content. A more modern name for cinder is scoria.

Correspondingly, are cinders good for plants? Like other volcanic rock, lava cinders have lots of pores resulting from expanding gasses when the stones are formed. These pores provide the perfect habitat for beneficial microbes to grow. Cinders are dense and will not float providing a more stable medium for growing plants.
