Abstract

Five of the top ten problems facing humanity (http://cnst.rice.edu/content.aspx?id=246) over the next 50 years (food, water, energy, environment and poverty) are directly related to the health of soil resources. Several different factors, including: (a) excessive tillage; (b) inappropriate crop rotations; (c) excessive grazing or crop residue removal; (d) deforestation; (e) mining and/or fracking; and (f) construction or urban sprawl, have contributed to the global problem of soil degradation. Understanding and implementing sustainable agricultural and land management practices that improve soil health is essential for mitigating and reversing these trends, if we are to successfully meet the needs of more than 9.5 billion people who will be sharing our fragile planet by the middle of the 21st century.The overall focus for this Special Issue was on agricultural factors contributing to soil degradation and suggested strategies for mitigating and reversing those trends. The discussion was anchored by invited contributions reflecting perspectives from Africa, Australia, China, Eastern Europe, India, Latin America, North America, Russia, and Western Europe. Voluntary contributions were evaluated, and incorporated into the issue to provide a global perspective on soil degradation and strategies to mitigate its devastating effects.This Special Issue draws upon published literature addressing soil quality and/or soil health, soil and crop management strategies to mitigate soil degradation, and future research needs and strategies that will steadily improve the fragile layer that lies between us and starvation. Your participation and contributions to this important endeavor were most welcome.

Abstract

The role of biochar in improving soil fertility is increasingly being recognized and is leading to recommendations of biochar amendment of degraded soils. In addition, biochars offer a sustainable tool for managing organic wastes and to produce added-value products. The benefits of biochar use in agriculture and forestry can span enhanced plant productivity, an increase in soil C stocks, and a reduction of nutrient losses from soil and non-CO2 greenhouse gas emissions. Nevertheless, biochar composition and properties and, therefore, its performance as a soil amendment are highly dependent on the feedstock and pyrolysis conditions. In addition, due to its characteristics, such as high porosity, water retention, and adsorption capacity, there are other applications for biochar that still need to be properly tested. Thus, the 16 original articles contained in this book, which were selected and evaluated for this Special Issue, provide a comprehensive overview of the biological, chemicophysical, biochemical, and environmental aspects of the application of biochar as soil amendment. Specifically, they address the applicability of biochar for nursery growth, its effects on the productivity of various food crops under contrasting conditions, biochar capacity for pesticide retention, assessment of greenhouse gas emissions, and soil carbon dynamics. I would like to thank the contributors, reviewers, and the support of the Agronomy editorial staff, whose professionalism and dedication have made this issue possible.

Abstract

The role of soils for achieving the Sustainable Development Goals is multifarious. Soils are the essential basis for food and biomass provision in support of food security (SDG 2) and energy security (SDG 7). Soil carbon sequestration is paramount for climate action (SDG 13). Soil-mediated water purification and retention, nutrient and matter cycling, and soils habitat functions are essential for maintaining ecosystem services and biodiversity (SDG 15). Healthy soils perform well in all these functions simultaneously. However, the globally increasing demand for food, fiber, and bio-based products poses massive challenges to soil health. Minimizing trade-offs between biomass production and soil health requires systemic approaches to assessment and governance of sustainable soil management in agriculture and food systems. It provides interdisciplinary insights into key questions: What are the impacts of agricultural management practices on sustainability targets in specific geophysical and socio-economic contexts? What are the opportunities and risks of future trends such as climate change, digitalization, and emerging technologies for soil management and soil health? How can institutions and governance instruments be improved to enable decision makers to take action on sustainable soil management? The book was initiated in the frame of the National German research program ‘BonaRes—Soil as a sustainable resource for the bioeconomy’, and it is meant to trigger interdisciplinary thinking.
