Healthy Soil Biology

Untitled

This presentation will cover the biology of what makes healthy soil and some of the human impacts on soil quality, erosion, etc. The study of soil ecology can be useful for both gardening and for application in the field of Environmental Science.

Introduction

Untitled

Human agricultural and industrial practices are degrading soil at a faster rate than it is naturally generated, and we have lost a third of our arable land over the course of only 40 years. (Milman, 2015). This puts the future of food production at great risk, especially with a fast-growing human population. Additionally, soil is Earth’s largest carbon sink and plays an important role in regulating the carbon cycle. (Thunberg, 2022). Soil is an important ecosystem that supports most of life on earth, and in most ecosystems, more biodiversity can be found in the soil than above it. (University of Minnesota, ret: 2023).
