Comparison of models and tools for the prediction of trace metals of farming soils

Having soils that meet international standards, where fertilizers have an adequate concentration of copper that do not degrade the soil, is very important for farming. In this context, reliable and quality information is needed to support decision-making on environmental risk issues, such as land use change, reduced fertilizer use time, the choice of those with fewer trace elements such as copper etc. For this reason, in very important software simulation that allows to estimate the effect of fertilizers on the concentration of traces in the future. Currently, it is possible to use Hydrus 1-D, which is a free access and internationally used software, which however is difficult to handle data and of high mathematical complexity. This research proposes to alternatively use a model implemented in Matlab, which performs functions equivalent to Hydrus 1-D, but with a soil database with a single screen input. As a result of the work, results and conclusions are delivered, which validate the experimental data and show the advantages of using this new software.
