Condizione: New. Instant Insights: Soil health indicators (Paperback or Softback).

Paperback. Condizione: New. This collection features four peer-reviewed literature reviews on soil health indicators.The first chapter describes indicators and frameworks for soil health currently in use. It evaluates the principles underpinning current approaches to monitoring soil quality/health and shows these principles have been applied in the development of a practical soil health toolkit for use by UK farmers.The second chapter reviews the range of physical, chemical and biological indicators of soil health and how they can be used in practice. It focusses on measuring soil health in organic vegetable cultivation and, in particular, ways of measuring the effects of adding organic amendments to improve soil health.The third chapter discusses key issues in soil organic carbon (SOM) modelling and the development of increasingly sophisticated, dynamic SOM models. It looks at the role of SOM models in improving soil health monitoring and developing decision support tools for farmersThe final chapter reviews current challenges in collecting more systematic and reliable data on earthworm communities, including issues in identifying different earthworm groups. It includes a case study on developing a robust method for accurate measurement of earthworm communities in soil in assessing and improving soil health.
