• Abstract:

   The high productivity of conventional agriculture is temporary, as it compromises future productivity due to its intensive soil use methods, in addition to the dependence on imported inputs that make up the formulations of soluble fertilizers, such as NPK. It is crucial to strengthen agricultural practices aimed at productivity and environmental conservation, employing the use of inputs and fertilizers in a sustainable manner. This work proposes a systematization of the concepts pertinent to the context of agrogeology and soil remineralization. Soil remineralization is a process that involves the replacement of plant nutrients in the soil using fine minerals with the aim of restoring soil fertility. They are divided into macronutrients, essential for plant metabolism and development (P, K, S, Ca and Mg) and micronutrients: beneficial (Na, Co, Si, Ni, Se and V) and essential (B, Cl, Cu, Fe, Mg, Mo and Zn). Normative Instruction, number: 5, of March 10, 2016, in its Article 4, sets out the criteria for specifications and guarantees that remineralizers must present for registration purposes with the Ministry of Agriculture, Livestock and Food Supply (M.A.P.A), in order to ensure efficiency and effectiveness in replacing NPK in agricultural crops.
