Outline: How should we understand soil productivity from a sustainable perspective?
Since the end of World War II the industrialisation of agricultural practices has been the leading scientific paradigm. However since Rachel Carson’s book “Silent Spring” (1962) documented the far-reaching impact of pesticide use on plants, birds and other organisms, we have also learned about the gradual impact of mineral fertilizers and other chemical and pharmaceutical inputs on soil productivity. Soil degradation, depletion and erosion are worldwide threats to food security. Thus we need a paradigm shift regarding productivity, one that includes all natural cycles in the soil and interactions between soils and plants. We have to think in a radical new way about what productivity means, and discuss measures for sustainable management of the natural capacity of healthy soils.
