Abstract

With the need to meet the global demand for food, agriculture has been developing in order to increase production, and one of the most used resources is fertilizers, with the aim of increasing the amount of nutrients in the soil and, consequently, obtain a greater gain in productivity. the fertilizers can be organic or inorganic, where the inorganic ones have known chemical structures, facilitating the correct dosage where they are used, in addition to increasing the speed of absorption of minerals by plants. However, the incorrect use of fertilizers, such as excessive use and application at the wrong time and in an inappropriate way, in an inappropriate place, it can cause several environmental problems, such as soil acidification, erosion, contamination by toxic substances, loss of nutrients, efficiency and biodiversity. Thus, this work presents studies of bibliographic surveys on compounds inorganic substances used as fertilizers.
