Soil fertility

Soil fertility is the ability of soil to sustain plant growth and optimize crop yield.

  • Biological soil fertility: The presence of living organisms in the soil, such as bacteria, fungi, protozoa, nematodes, worms, etc.
  • Chemical soil fertility: The availability of nutrients for plants.
  • Physical soil fertility: The structural characteristics of the soil, such as grain size, moisture retention capacity, potential for erosion, compaction, draining and leaching of nutrients.
