Despite the title, this blog post is not about sex, unless we consider the teeming reproductive activity of billions of micro-organisms in every tablespoon of fertile soil.
I’m writing for those who wonder how important soil health is. Over the years, advocates for sustainable agriculture have promoted the importance of many different goals: fewer pesticides, less soil erosion, fertilizer efficiency, water stewardship, the well-being of small farmers, less food waste. And so on. We have tools with multiple indicators, but scant analysis of how goals affect one another, and hence little understanding of systemic cause and effect.
