  • Clay Soil. Clay Soil is a heavy soil type that benefits from high nutrients.

  • Peat Soil.
  • Chalk Soil.
  • Loam Soil.

Will we run out of soil?

In the US alone, soil on cropland is eroding 10 times faster than it can be replenished. If we continue to degrade the soil at the rate we are now, the world could run out of topsoil in about 60 years, according to Maria-Helena Semedo of the UN’s Food and Agriculture Organization.

Which soil is rich in human?
