Enhanced top soil carbon stocks under organic farming.
It has been suggested that conversion to organic farming contributes to soil carbon sequestration, but until now a comprehensive quantitative assessment has been lacking. Therefore, datasets from 74 studies from pairwise comparisons of organic vs. nonorganic farming systems were subjected to metaanalysis to identify differences in soil organic carbon (SOC). We found significant differences and ...
متن کاملLong – Term Tillage and Manure Effect on Soil Physical and Chemical Properties and Carbon and Nitrogen Mineralization Potentials
The objective of this work was to study the effects of tillage and liquid manure applications on some physical and chemical properties as well as on the carbon and nitrogen mineralization potential of a meadow soil. Our results indicated that tillage and manure applications had no effect on the concentration of Cu, Mn, total N and organic C in 0-15 cm layer of soil after 15 years of treatment. ...
متن کاملRyegrass - derived pyrogenic organic matter changes organic carbon and nitrogen mineralization in a temperate forest soil
Pyrogenic organic matter (PyOM) is considered as a technique to improve soil fertility and store carbon (C) in soil. However, little is known regarding soil organic C and nitrogen (N) mineralization in PyOM-amended soils. To investigate the relationship between the C and N mineralization rates and the possible consequences in terms of C storage and N availability, we incubated ryegrass-derived ...
متن کاملPlan B Project for Master in Statistics: The Effect of Farming Practices on Changes in Soil Organic Carbon and Nitrogen
The amount of organic carbon and nitrogen stored in the soil are thought to be related to climate change. This collaboration with researchers from the Department of Soil, Water, and Climate investigated the effects of farming practices on changes in soil organic carbon and nitrogen. Specifically, the effects of irrigation systems and the amount of manure applied were studied using soil samples ...
