Black carbon (BC) is an important fraction of many soils worldwide and plays an important
role in global C biogeochemistry. However, few studies have examined how it influences the …

The quantity and chemical composition of soil organic carbon (C) are primary factors
controlling the growth and activity of soil microorganisms. However, availability of …

The chemical composition and quantity of plant inputs to soil are primary factors controlling
the size and structure of the soil microbial community. Little is known about how changes in …

Altered rates of native soil organic matter (SOM) mineralisation in the presence of labile C
substrate ('priming'), is increasingly recognised as central to the coupling of plant and soil …

Background and aims Biochar additions to tropical soils have been shown to reduce N
leaching and increase N use efficiency. No studies exist verifying reduced N leaching in field …

Although roots are an important source of soil organic matter (SOM) and are thought to be
the major constituent of the particulate organic matter (POM) fraction, few studies have …

Root-deposited photosynthate (rhizodeposition) is an important source of readily available
carbon (C) for microbes in the vicinity of growing roots. Plant nutrient availability is …

The productivity of temperate forests is often limited by soil N availability, suggesting that
elevated atmospheric N deposition could increase ecosystem C storage. However, the …

Plants often impact the rate of native soil organic matter turnover through root interactions
with soil organisms; however the role of root-microbial interactions in mediation of the …

Understanding the dynamics of soil C is key to managing soil organic matter to enhance soil
quality and ecosystem functioning, and reduce trace gas emissions from soils. Our objective …
