Characterization of soils irrigated with untreated urban wastewater using multiway techniques

This work aims to characterize the different types of soils corresponding to citric fruits and rice, with the target of determining those variables that affect them. All this is carried out using a Tucker3 model, through the use of loading plots for all modes. Heavy metal, soil properties, and their evolution with depth are studied for different locations grouped in predefined agricultural parcels. Differences between the rice and the citric fruit soils have been determined according to them, and also different behaviors of the variables within each type of soil, for the parcels analyzed.
