“…crop brings environmental risks that include a potential impact on tropical soil ecosystem sustainability (NAVARRETE et al, 2018). The increased need for fertilizers due to the expansion of sugarcane production is a threat to the ability of the soil to maintain its potential for selfregulation in the long term, i.e., its sustainability (SCHWAB et al, 2023). Soil management practices used in sugarcane agriculture require synthetic mineral fertilizers (nitrogen/phosphorus/potassium -NPK) and full recycling of waste products from the RESUMO: Neste estudo avaliou-se a hipótese de que a combinação de Nitrospirillum amazonense estirpe BR11145 com adubo biológico preparado com base em microbioma autóctone da localidade de aplicação do produto, produzido com Microgeo ® , resulta em benefícios morfológicos e nutricionais para o desenvolvimento inicial de plantas de cana-de-açúcar e para a química do solo.…”

In this study, we analyzed the hypothesis that the combination of Nitrospirillum amazonense strain BR11145 with biological fertilizer prepared using Microgeo® and native microbiome from location of the product application results in morphological and nutritional gains for the initial development of sugarcane plants and soil chemistry. For this purpose, pre-sprouted sugarcane seedlings were grown in a greenhouse mesocosm experiment using soil amended with nitrogen/phosphorus/potassium fertilizer. The experimental treatments consisted of: 1) biological fertilizer with the addition of N. amazonense (100 mL ha-1), 2) biological fertilizer without the addition of N. amazonense, 3) inoculation with N. amazonense at a dose of 100 mL ha-1 with 2x108 viable cell mL-1, 4) inoculation with N. amazonense at a dose of 200 mL ha-1 with 2x108 viable cell mL-1, and 5) control, without the addition of biological fertilizer and N. amazonense. The biological fertilizer was applied at dose of 300 L ha-1, which was split at planting (200 L ha-1) and in the post-emergence phase (100 L ha-1). After 164 days of planting, it was detected an increase in leaf length +3, number of green leaves, leaf area and sulfur content in the leaves of sugarcane plants that received the biological fertilizer with the addition of N. amazonense. In conclusion, the combination of N. amazonense with biological fertilizer revealed positive effects through morphological and nutritional characteristics in sugarcane plants during their early stages of development when compared to plants grown only with the inoculation of N. amazonense, biological fertilizer or mineral fertilizers, with few notable positive effects on soil chemistry.
