why does soil fertility depend on the presence of humus?
Answers
Explanation:
The foundation of any food system is the availability of healthy soil. Healthy soil is one which contains decomposed organic matter or compounds that are undergoing the process of decomposition to produce humus. Furthermore, such soil produces healthy crops that in turn provide nourishment for the well-being of consumers. Crops obtain their nutrients from both organic matter and minerals. The organic matter is essentially what is termed as humus – healthy soil component made up of animal and plant residues that decompose to nourish the plants or improve soil fertility.
