Replicate data on:  Roots and other residues from leys with or without red clover; quality and effects on N2O Emission Factor after ploughing
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Detailed data of the soil characteristics, field management, amount and N content of below (roots +crown) and above (stubble and herbage) ground grass mixture, red clover and red clover grass swards at the end of the 3rd production year, together with fluxes of greenhouse gas emissions (N2O, CO2, CH4) and soil air composition (CO2, N2O, CH4, N2 and O2) of a field experiment in Norway.These data supplement the findings presented in the corresponding research article “Roots and other residues from ley with or without red clover: quality and effects on N2O Emission Factor after ploughing”. For understanding of the effects of incorporating ley above and below ground residues on cumulative greenhouse emissions refer to article from this research.</p' .
