Description :
The main aim of this work was to search for chaotic parameters using some basic concepts of nonlinear dynamical system theory with spatial series of soil properties. Three spatial series consisting of 1000 data point transects were used. The AA. selected horizontal and vertical electrical conductivity (ECh and ECv, respectively) and gravimetric water content from a vertisol (Typic Hapludert) under rice cropping. Each spatial transect was oriented from South to North with 1-m spacing. It was used the TISEAN Software Package for deriving nonlinear parameters from spatial series. All the spatial series showed a higher deterministic component.
