Linking soil microbiome with sustainability

ustainable agriculture depends on healthy soil and soil microbial diversity and thus must focus on managing soil microbes to
deliver more efficient ecosystem services to crops. Moreover, intensified crop production demands integrated nutrient management
systems to maintain agricultural productivity and protect the environment. Using beneficial native microbes that promote plant
health and quality, and recycling crop residues with low environmental impact are ultimate practices for sustainable food and energy
production. Here I will present our studies on using biological native resources (beneficial bacteria and fungi) and recycling organic
residues for sustainable crop production. Our studies have shown that sugarcane endophyte bacteria and fungi when inoculated in
plantlets promote sugarcane plants growth, quality and health (microorganisms antagonistic to sugarcane pathogens). Subsequently
following the crop cycling production, our studies on recycling of crop residue as a sustainable practice, showed that the combination
of sugarcane residue (vinasse), rich in carbon, nitrogen and potassium when applied together with inorganic fertilizer, emits more
nitrous oxide than inorganic fertilizers through nitrification process carried out by bacteria. To mitigate N
2
O emissions we showed
that the use of inhibitors of nitrification is a practical solution and, more importantly these compounds do not affect soil-borne
microbial community diversity.
