Soil organic matter pools and carbon fractions in soil under different land uses.

This study investigated changes in the content of soil organic matter (SOM) and humic substances (fulvic acid, humic acid and humin) of soil under different land uses. On an integrated coconut orchard, the presence of cover crops and the management of crop residues led to an increase of SOM content. However, cultivation on the same area resulted in a substantial loss of fulvic acids in the top-most layer of soil, indicating a reduction in organic material that enhances soil physical properties and improves plant growth.

Status of the World’s Soil Resources

A reference document on the status of global soil resources that provides regional assessments of soil change. The information contained inside is based on peer-reviewed scientific literature, complemented with expert knowledge and project outputs. It provides a description and a ranking of ten major soil threats that endanger ecosystem functions, goods and services globally and in each region separately. It also describes direct and indirect pressures on soils and ways and means to combat soil degradation.

Nutrient stripping: the global disparity between food security and soil nutrient stocks.

Despite increased food production, modern agricultural systems are inherently leaky and unsustainable, particularly with regard to excessive nutrient mining. This paper uses case studies to investigate the global extent of this issue, specifically the failure of macronutrient (e.g. nitrogen, phosphorus) management to deliver continued improvements in yield, and the failure of agriculture to recognise the seriousness of micronutrient depletion (e.g. copper, zinc, selenium). It advises that agricultural sustainability can only be achieved using a whole-systems approach that socially and environmentally re-engineers agricultural systems at all scales.
