It takes over 100 years to form just 1 inch of topsoil.π±π
This rate depends on several factors, including parent rock material, climate and weathering conditions, organic material accumulation, vegetative cover and land use, and biological activity like worms, fungi, and microbes.
In areas with rich biological activity and moisture, topsoil might form in 100 years. In dry, cold, or heavily disturbed regions, it may take 500 to even 1000 years!
Soil is a living and slowly renewing resource. Protecting what we have is much easier than rebuilding what we lose.
