摘要: Lemke, R. L., VandenBygaart, A. J., Campbell, C. A., Lafond, G. P., McConkey, B. and Grant, 2012. Long-term effects of crop rotations fertilization on soil C N in a thin Black Chernozem southeastern Saskatchewan. Can. J. Soil Sci. 92: 449-461. Carbon sequestration is important due to its influence fertility impact the greenhouse gas (GHG) phenomenon. influenced by agronomic factors, but what extent still being studied. studies provide one best means making such assessments. In this paper we discuss quantify effect cropping frequency, fertilization, legume green manure (LGM) hay crops rotations, tillage organic carbon (SOC) changes Chernozemic fine-textured This was based 50-yr (1958-2007) rotation experiment which initiated land that had previously been fallow-wheat (Triticum aestivum L.) (F-W), or F-W-W...
