The Nature and Amount of the Fluctuations in Nitrate Contents of Arable Soils

摘要: The study of the fluctuations in amounts nitrate present arable soils is important both from practical and scientific points view. supply soil very commonly a limiting factor crop production Great Britain, so that any process which increases tends to increase productiveness, vice versa. From point view interest even wider. No constituent, not moisture, shows such great as nitrates, none susceptible external influences. Further, represents end one chain decompositions amount formed over given period therefore measure extent this particular decomposition has proceeded.
