Soil characteristics, especially those which affect productivity, have a controlling influence on the diversity and balance of plant species on a site. Soil Porosity and Permeability. Soil fertility is the ability of a soil to sustain plant growth by providing essential plant nutrients and favorable chemical, physical, and biological characteristics as a habitat for plant growth.Plant nutrients include the macronutrients nitrogen, phosphorus and potassium, sulfur, calcium and magnesium. Soil fertility is the capacity of the soil to supply mineral nutrient elements to crop. Soil is considered fertile if it is productive, that is, if it can support lush healthy growth of desirable plants, whether they be garden plants, landscape plants, or crops.
