Humic Substances in Terrestrial Ecosystems.
No full textThis book highlights the increasing importance of humic substances in the different scientific fields related to terrestrial ecology, soil quality conservation, and environmental chemistry. It shows that modern humic substances research is not only directed to unravel their yet ill-defined chemical structure but is successfully exploring the interconnected chemical, biological, and physical processes that maintain the ecological equilibrium of soil and ensure a sustainable agricultural production. The book will primarily be of interest to soil scientists and to ecological and environmental scientists. People in the fields of forest science, agronomy, analytical and environmental chemistry, water science, environmental engineering, and coal science will also find this publication worthy of their attention.Includes bibliographical references and index.Chapter 1.

Metodo per sequestrare il carbonio organico in un suolo
No full textLa presente invenzione concerne un metodo per sequestrare il carbonio organico in un suolo, caratterizzato dal fatto di comprendere le seguenti fasi operative: a) porre a contatto un suolo comprendente humus con un catalizzatore comprendente un complesso di tipo metallo-porfirina e/o metallo-ftalocianina; b) esporre detto suolo comprendente humus a contatto con detto catalizzatore a radiazioni elettromagnetiche aventi lunghezza d’onda nell’intervallo dell’UV e/o del visibile. In particolare, il suddetto metodo è utilizzabile per mitigare l’emissione di CO2 prodotta naturalmente da un suolo e migliorare la stabilità strutturale di un suolo, così da limitare le perdite di suolo fertile a causa dell’erosione superficiale
