The agricultural sector is extremely socioeconomically relevant in Brazil. Agricultural production systems are dynamic and they currently focus on plant production, with emphasis on sustainability and soil health aimed at ensuring the regenerative agriculture implementation by using natural inputs rather than the chemical ones. The objective of the present study is to investigate Rekal soil remineralizer effects on the biological health of soils cultivated with soybeans in four experimental sites located in Goiás State under different soil conditions and agricultural management procedures. The experiment followed a randomized block design with four treatments, namely: the standard treatment with potassium chloride (KCl) and three treatments based on increasing the remineralizer doses. Soil samples were collected before treatment application and after the crop cycle was over. The samples were used to assess soil biological health based on the BioAS methodology (Embrapa), which includes physical, chemical and biological indicators, with emphasis on the activity of enzymes β-glucosidase and arylsulfatase, organic matter content and soil quality indices. According to the results, there were significant increase in the activity of enzymes β-glucosidase and arylsulfatase, organic matter accumulation and improved soil chemical and biological quality indices in comparison with the standard treatment (without Rekal remineralizer application). This finding pointed out that Rekal is a technological and sustainable alternative capable of both enhancing nutrient cycling and improving featured related to soil fertility and resilience in soybean production systems.
