Zubris and Richards9 found synthetic fibers using polarized light microscopy in several soils in the U.S. to which organic wastewater sludge had been applied.
Initially, several soils were assessed as sensible heat storage mediums, with sand and gravel selected as the most appropriate.
Carbonate leaching rates in several soils in Switzerland and in the Lake Constance region were calculated and related to landscape development.
Diffusion tube experiments were carried out using several soils packed to field densities to determine the effective diffusivity of chloride ion as a function of soil moisture content.
In this work we analysed the rhizobia present in nodules of the variety "Riñón" in several soils from León province in order to select native rhizobial strains to be used as biofertilizers.
Validations with data from several soils indicated that the approach offers consistent and accurate predictions of PCCs when used with Zapata's model for plastic soils and with the Mechanistic Empirical Pavement Design Guide (MEPDG) model for non-plastic soils.
