Instant Insights: Using Manure in Soil Management
Häftad, Engelska, 2024
667 kr
Skickas inom 5-8 vardagar
This book features five peer-reviewed reviews on the utilisation of manure to improve soil management and health.The first chapter reviews ways to improve manure management in animal housing during storage and after application in the field. The chapter also considers manure application methods and their effects on nitrogen utilisation and soil carbon storage.The second chapter discusses the role of manure and compost in maintaining soil health, as well as ways of integrating livestock and crop production to optimise soil health.The third chapter reviews the impacts associated with the application of livestock and poultry manure on the ability of soil to deliver a range of ecosystem services that sustain plants, animals, people and the environment.The fourth chapter discusses the responsible storage, treatment and processing of livestock manure, as well as the measures available to mitigate the production of greenhouse gas emissions during these processes, such as slurry mixing.The final chapter reviews the main technologies for manure valorisation into bioenergy and biofertiliser products. It discusses developments in more established technologies such as solid-liquid (S/L) separation, as well as more innovative techniques, such as ammonia stripping/scrubbing.

Instant Insights: Regenerative Techniques to Improve Soil Health
Häftad, Engelska, 2024
667 kr
Skickas inom 5-8 vardagar
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.

Instant Insights: Organic Soil Amendments
Häftad, Engelska, 2025

Skickas inom 5-8 vardagar
This book features four peer-reviewed reviews on organic soil amendments.The first chapter examines the role of biofertilisers and consortia of microorganisms in improving the effectiveness of organic fertilisation, before moving on to consider the use of animal excrement, including manures, slurry and guano. The chapter also considers the use of products or by-products of both animal and plant origin as fertilisers.The second chapter provides a critical evaluation of the potential of compost to improve soil health, as well as the sources of variability and potential risks of compost for environmental quality. Two case studies evaluate the trade-offs between benefit and risks in the use of compost in perennial and annual crops.The third chapter discusses optimising slurry management in agricultural practices and highlights current decision tools for optimising manure management. It also reviews modifying animal slurry pH to enhance its value as a biobased fertiliser through methods such as bio acidification and alkalinisation.The final chapter provides an overview of the main technologies for manure valorisation into bioenergy and biofertiliser products. It discusses developments in more established technologies such as solid-liquid (S/L) separation, anaerobic digestion and composting, as well as more innovative techniques, including struvite precipitation.
