Soil is the Earth's living skin. It provides anchorage for roots, holds water long enough for plants to make use of it and the nutrients that sustain life. This book is about the best soil in the world - the black earth or chernozem: how it is being degraded by farming and how it may be farmed sustainably.
Industrialisation of farming has laid bare contradictions between the unforgiving laws of ecology and economics. Soil organic matter is the fuel that powers soil systems and the cement that holds the soil together but agriculture is burning it up faster than it is being formed: even the chernozem cannot long survive this treatment.
Here is the evidence for this trend and, based on long-term field experiments, ecological principles for sustainable agriculture that can reverse the trend and, at the same time, feed the world.
