This work determines field capacity and moisture retention through correlation and regression analysis, based on physical and chemical properties in Alfisols and Ultisols in the State of Rio de Janeiro (Brazil). The field capacity was estimated “in situ” by the direct method. The other properties were obtained by laboratory methods. Studies were developed in accordance to different levels of data analysis: global or partial (local). The correlation study showed that microporosity and contents…
