Soil doesn’t just exist in nature and rural areas, it lies beneath our buildings and roads in urban areas. Soils are incredibly diverse, given the changing climates and topography across the planet. Some soils have higher salt content, others are desert soils. Each flavor of soil supports certain plants, even though they may seem like “harsh” environments.
One key question in permaculture is, how can we design our communities to blend in with the natural environment? Every community has different characteristics and needs. Climate differs in the city than the countryside. Larry discusses composting mechanisms, trees and fungi, soil microbes, soils in non-farming ecosystems, deserts, urban environments, and community-centered design.
