Soil formation is a stage in primary succession.


Soil formation is a stage in primary succession.

After the bare land has been created or newly exposed, hardly organisms called pioneer species are blown or transported in some way or another onto the bare land. These species can survive without soil. Pioneer species typically have light seeds that disperse easily through wind. Grasses, mosses, lichens, and other plants are pioneer species.

As these pioneer plants live, attract consumers, and die, soil is either formed or improved to the point where other plants will begin to grow.

The surface of the bare land may also be eroded by wind, water, and other processes simultaneously, which also contributes to the formation of substrate. This may happen before the pioneer species arrive and it may continue to happen after their arrival if enough surface is exposed.
