Managing for Healthy Soils
AgGuide - A Practical Handbook
We are told that in a teaspoon of soil there may be more organisms than the total number of people on the planet. Who is conducting the count? And what does it mean? To be brutal about it: So what?
We now know that just as biodiversity and balance is important in our agricultural and natural systems and landscapes to keep them healthy and robust, the same processes are vital for our soils. There’s a lot going on down there that deserves a closer look. And even if we can’t see it, a healthy, living soil will grow better plants, be more resilient and improve our agricultural productivity.
So this book is designed to for a twin purpose:
• to make up for the mechanistic approach of 40 years ago—to present a clearer picture of what remained a secret to the uninitiated for so long—to reveal the living, pulsing, teeming world beneath our feet, and
• to help manage our soil resource by understanding that any actions we take will have an impact on soil health.
Managing for Healthy Soils is a must for any farmer, horticulturalist or home gardener. It explains how to class your type of soil, understand the limitations and potential, and manage it sustainably. Soil tests for moisture, water infiltration, pH, soil nutrients, soil texture, soil compaction, structural stability and more will help you understand your soil context.
