Abstract

A soil data-base facilitated by the Secretaría de Agricultura y Recursos Hidráulicos-204 sites-is used to evaluate selected physical and chemical properties of soils irrigated with sewage water. Semivariograms were elaborated to evaluate spatial dependence of boron, carbonates, electric conductivity, chloride, pH and organic matter for the upper 30 cm. Three of the six parameters-boron, electric conductivity and organic matter-seem to be relatively spatially dependent, but no clear dependence was found in the case of pH, carbonates and chloride... In order to continue, download full text in PDF.
