Brazil is an agricultural country and extremely dependent on chemical fertilizers from the international market. The principle of using remineralizers or repair as fertilizing properties, used physical or biological soil, being in agriculture as a sustainable alternative of natural fertilization to soils. In this context, the research aimed to evaluate the agronomic efficiency of increasing doses of the remineralizing potential RR1971, in the cultivation of corn with a sandy texture, from the municipality of Piranhas, Goiás. The experiment was carried out under greenhouse conditions, in an experimental area of the Escola de Agronomia, Universidade Federal de Goiás, linked to the UFG NucliSolos Agroambiental Program. The doses used were: control (without application); 30 kg. ha-1 of K2O from RR1971 remineralizer; 60 kg.ha-1 of K2O from RR1971 remineralizer; 120 kg.ha-1 of K2O from RR1971 remineralizer, 240 kg.ha-1 of K2O from RR191 remineralizer, 60 kg.ha-1 of K2O from FMX remineralizer and 60 kg.ha-1 of K2O from synthetic fertilizer from my . It is concluded that there is release of potential for function in the soil and that plants can increase in productivity of growth productivity1971 increase in potential of increasing doses RR197.
