Farms were located in Rio Grande do Sul State, in Brazil, one of the most representative regions of organic agriculture in the country. Samples of all N sources for cropping in each farm were collected. Lettuce, strawberries and tomatoes produced under organic, conventional and hydroponic cropping systems were sampled on these farms.  aAgriculture  aCropping systems  aHydroponics  aIsotopes  aNitrogen  aAgricultura Orgânica  aCultivo Hidropônico  aIsótopo  aNitrogênio  aSistema de Cultivo  aDelta-N-151 aNUNES, J.
