Experimental study of the impact of the chrome from high energetic efficient fertilizers on the soil

Brazilian environmental legislation on the effects of some chemical elements discarded on the soil is still very recent, especially regarding the various transformations of different types of chromium that can be used together with fertilizer made of leather scraps. This fact is mainly due to lack of experimental data that show clearly the various modifications undergone by the various types of chromium released into the earth's crust, associated with fertilizers. This very fact does not occur in many developed countries, such as Italy for example, where there are already several studies on the effects of various types of chromium, which are used in conjunction with leather fertilizer. This work presents an experimental study on the behavior of chromium (III) in arable soil, using hydrated leather fertilizer as energy-efficient fertilizer.
