How many days does it take to make one inch of topsoil?

Answer 1

It typically takes hundreds to thousands of years to form just one inch of topsoil through natural processes such as weathering, organic matter decomposition, and microbial activity. Some estimates suggest that it can take about 500 years to create one inch of topsoil under ideal conditions. Therefore, the process is extremely slow and underscores the importance of preserving existing topsoil.
