              Abstract
              Repeated fertilisation of crops with manure commonly increases both the amount and the quality of soil organic matter the mineralisation of which strongly determines the availability of N to plants In the rhizosphere the microbial mineralisation/immobilisation of N is enhanced due to rhizodeposition release of organic compounds from roots In this work we studied N transformations during incubation of maize root mucilage in soils that had been previously fertilized with composted pig manure or with ammonium nitrate for 7 years Our work revealed mucilage was rapidly mineralised average halflife of 3 days inducing a rapid N immobilisation of 94 mg N g−1 of mucilage C followed by a slow remineralisation Fertilisation with manure induced a persistent stimulation of the soil organic matter mineralisation leading to an enhanced content of soil inorganic N +23 in 58 days of incubation Due to this stimulation of microbial activity in the soil fertilized with manure the decrease in inorganic N during the biodegradation of mucilage lasted a shorter time as compared to the mineral fertilisation However the type of fertilisation did not significantly change the amount of N immobilisedThis work was funded by the ‘Green pork production’ research initiative on environmentfriendly pig production The authors address special thanks to V Boitel ARVALIS Vegetal Institute Le Rheu France for providing the experimental plots We also thank S Bienaimé for inorganic N analysis S Deschaumes and P Marchal for their helpful contribution to the experiment
