Managing soil fertility in organic farming systems

12 Complex relationships exist between different components of the organic farm and 13 the quantity and quality of the end products depend on the functioning of the whole 14 system. As such, it is very difficult to isolate soil fertility from production and 15 environmental aspects of the system. Crop rotation is the central tool that integrates 16 the maintenance and development of soil fertil...

Soil organic carbon dynamics jointly controlled by climate, carbon inputs, soil properties and soil carbon fractions.

Soil organic carbon (SOC) dynamics are regulated by the complex interplay of climatic, edaphic and biotic conditions. However, the interrelation of SOC and these drivers and their potential connection networks are rarely assessed quantitatively. Using observations of SOC dynamics with detailed soil properties from 90 field trials at 28 sites under different agroecosystems across the Australian ...

Comment on "Managing soil carbon" (II).

Lal et al. have recently argued (1, 2) that restoring soil carbon levels worldwide is important for a number of purposes, including reducing atmospheric CO 2 concentrations. We agree, but we question how much eroded soil C is ultimately delivered to the atmosphere. Previous estimates of the proportion of eroded soil carbon oxidized range from 0% to near 100% (3, 4). We believe that the true val...
