		<abstract>The objective of the present work was to quantify Fe2O3 by laboratory and orbital sensors. The study area was a 473 ha bare soil field located in the region of Barra Bonita, SP. A sampling grid was established (100 m x 100 m) and the places were georreferenced. In these points, earth samples were collected in two depths (0-20; 80-100cm) for laboratory analyses and reflectance obtaintion with a laboratory sensor (450 to 2500 nm). In the same places of soil sampling collection, reflectance data were obtained from a TM-Landsat-5 image. Most of the generated equations showed high r2 for Fe2O3, 0,82 for laboratory and 0,67 for orbital. Comparing the intervals of iron between values esteemed by radiometric data and values determined in laboratory analyses, radiometric data presented a global success of 92,2% against 91,3% for orbital data. The majority of the confusions observed between the determined values and the quantified ones are in an acceptable interval.</abstract>
