Soil carbon dynamics and nutrient cycling
Chapitre 7 Section 2 SPE EcolDur; The quantity of organic carbon in soil and the quantity and type of organic inputs have profound impacts on the dynamics of nutrients. Soil organic matter itself represents a large reservoir of nutrients that are released gradually through the action of soil fauna and microorganisms: this is especially important for the supply of N, P and S to plants, whether agricultural crops or natural vegetation. Organic matter also modifies the behaviour and availability of nutrients through a range of mechanisms including increasing the cation exchange capacity of soil, thus leading to greater retention of positively charged nutrient ions such as Ca, Mg, K, Fe, Zn and…
Soil carbon, multiple benefits
Made available in DSpace on 2018-12-11T17:24:47Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-01-01 In March 2013, 40 leading experts from across the world gathered at a workshop, hosted by the European Commission, Directorate General Joint Research Centre, Italy, to discuss the multiple benefits of soil carbon as part of a Rapid Assessment Process (RAP) project commissioned by Scientific Committee on Problems of the Environment (SCOPE). This collaboration led to the publication of the SCOPE Series Volume 71 Soil Carbon: Science, Management and Policy for Multiple Benefits; which brings together the essential scientific evidence and policy opportunities regarding the global importa…
