Crop Rotation and Nitrogen Effects on Normalized Grain Yields in a Long-Term Study

information is available on their effect on year-toyear variability. Effects of year-to-year variability in agricultural production systems There have been several attempts to analyze what have always been a concern, but few studies are conducted for a long effect these different aspects of management may have enough period of time where management system evaluations and assessments can be made...

Effect of Crop Rotation and Nitrogen Fertilization on the Quality and Quantity of Soil Organic Matter

Particulate Organic Matter Affects Soil Nitrogen Mineralization under Two Crop Rotation Systems

Changes in the quantity and/or quality of soil labile organic matter between and after different types of cultivation system could play a dominant role in soil nitrogen (N) mineralization. The quantity and quality of particulate organic matter (POM) and potentially mineralizable-N (PMN) contents were measured in soils from 16 paired rice-rapeseed (RR)/cotton-rapeseed (CR) rotations sites in Hub...
