Paperback. Etat : New. This book features four peer-reviewed reviews on regenerative techniques to improve soil health.The first chapter discusses some common issues regarding the use of bio-based fertilisers, such as the concentration of nutrients leading to losses of reactive nitrogen (N) and phosphorus into the environment.The second chapter provides a critical evaluation of the potential of compost to improve soil health, as well as its effect on soil nutrient cycling, soil hydraulic properties, crop productivity, soil biodiversity and environmental quality. Two case studies on the benefits and risks of using compost in perennial and annual crops are also included.The third chapter reviews the benefits of service crops, including cover and catch crops, in both intensive cropping systems and low input systems. The chapter discusses an array of studies from temperate Europe to illustrate these benefits, including the use of service crops for reducing N leaching losses.The final chapter addresses how crop rotations affect nitrogen flows in organic farming systems and how these rotations can be utilised to optimise the nitrogen cycle and improve nitrogen use efficiency. The chapter utilises 30 years' worth of data collected from over 90 different temperate field studies published between 1990 and 2020.…

Paperback. Etat : New. This book features five peer-reviewed reviews on biofertiliser use in agriculture.The first chapter examines the role of biofertilisers and consortia of microorganisms to improve the effectiveness of organic fertilisation, before moving on to consider the use of animal excrement, including manures, slurry and guano.The second chapter presents the key issues in the optimum use of treated wastes in crop nutrition. The chapter also discusses technical processes such as precipitation of salts, incineration and post-treatment of ashes, as well as production of carbonaceous materials.The third chapter discusses some common issues regarding the use of bio-based fertilisers, such as the concentration of nutrients leading to losses of reactive nitrogen and phosphorus into the environment.The fourth chapter addresses the key issues of arbuscular mycorrhizal fungi (AMF) and soil health, specifically focussing on improved soil structure and stability, soil contamination, carbon sequestration and nutrient retention.The final chapter provides an overview on the use of plant growth-promoting bacteria/rhizobacteria (PGPB/PGPR) and its consequent effects on plant and soil health. The chapter also explores interactions between PGPB/PGPR and other components of the rhizosphere, such as AMF.…
