Tóth, T. and M. Kertész. 1996. Application of soil - vegetation correlation to optimal resolution mapping of solonetzic rangeland. Arid Soil Research and Rehabilitation.10:1-12. An optimal resolution surveying technique was developed and tested in the solonetzic grassland of Hortobgy, Hungary. Indication of soil properties by vegetation is utilized 1.) to create a sampling design by applying satellite image of the pilot area and 2.) to estimate soil properties on the basis of statistical correlation between vegetation and of soil data. Spatial sampling scheme was designed in accordance with the local heterogeneity of the satellite image. In order to study the predictability of the vegetation categories in terms of soil chemical properties, discriminant analysis was used with pH, electrical conductivity and sodium activity of 3 depths as grouping variables. Based on the taxonomy of vegetation types about two thirds of the cases can be classified and correlated with the soil chemical properties.
