Why Are the Top 4 Inches in Topsoil the Most Important Gift for Life on Earth?

“Everything is connected to everything else. Everything must go somewhere. Nature knows best. There is no such thing as a free lunch. If you don’t put something in the ecology, it’s not there.” Barry Commoner: The Closing Circle, Making Peace with the Planet

No trick question: You have a choice between a box of fertile topsoil and a bag of gold coins. What would you choose? Maybe you’ll change your mind after reading this answer.

  1. Humus formation is a biological process of the ecosystem where the energy flow starts with the sun through photosynthesis to help plants make food that is consumed by animals. The last stage is decomposition of organic waste matter in order to release carbon back to the air and convert dead biomass back into mineral nutrients like nitrogen compounds, phosphorus, sulfur, calcium, potassium, and magnesium.
  • Regulates water retention
  • Recirculates oxygen and accumulates carbon
  • Decomposes organic matter into mineral elements
  • Suppresses pests, parasites and diseases
  • Controls plant growth
  • Recycles nutrients for plant roots, microorganisms, bacteria, fungi and litter-feeding insects (larvae, crickets, ants, termites)
  1. Mechanized rough tillage of soil upsets fragile soil structure
  2. Failure to protect microbes… misunderstanding their importance. Microbe life can be nurtured by using cover crops and feeding them with fish emulsions
  3. Failure to build organic matter after using chemical fertilizers. Important to add various crop covers to maintain organic matter in the soil for abundant micro-life and strengthen vigorous roots.
