Estimativa da água disponível do solo por meio da teoria fractal.

Abstract

Many researches, in several areas, have been done using fractal geometry, it has been useful to estimate soil physical hydric properties, thus the objective of this work was to determine the availability of water of the soil (AD) using fractal theory based on two easy physical properties, the water retention curve (DSWRC) and the distribution curve of soil particles (DPSD ). Using the fractal theory by the determination of fractal dimension (D) based on the water retention curve permitted to estimate, with high precision, the availability water values, using Brook and Cary model.
