Summary

Agriculture needs detailed information about the variability of cause and effect relation-ships between soil properties and agricultural crops. Often the difficulty in obtaining such information is in the number of required samples in these studies. The objective of this study is to use the magnetic susceptibility (MS) to predict soil attributes and citrus trees in order to facilitate the identification and development of specific areas of management. The study area is located in the municipality of Gavião Peixoto, SP, under the occurrence of an Oxisol, which is installed an orchard of pêra-rio orange under limão cravo for 14 years. A sampling grid was drawn at regular intervals of 50 m, a total of 312 points in an area of 93.58 hectares. We analyzed the chemical and physical attributes related to soil and plant. Data were analyzed using geoestatistics and multivariate statistics. The results indicate that the magnetic susceptibility proved to be a promising tool in identifying areas with higher productive potential.
