Saulo Augusto Quassi de Castro

Saulo Augusto Quassi de Castro is a Guest Researcher at the Department of Plant and Environmental Sciences, University of Copenhagen, specializing in plant and soil sciences. His research focuses on nitrogen dynamics in agricultural systems, particularly in sugarcane and wheat production.

His educational background includes an Agricultural Engineering degree (2014), Master's (2017), Specialist (2020), and Doctorate (2022) in Soils and Plant Nutrition from Luiz de Queiroz College of Agriculture (ESALQ/USP) at the University of São Paulo.

• Agricultural Engineer (2014) - Universidade de São Paulo
• Master in Soils and Plant Nutrition (2017) - Universidade de São Paulo
• Specialist in Soils and Plant Nutrition (2020) - Universidade de São Paulo
• Doctor in Soils and Plant Nutrition (2022) - Universidade de São Paulo

Dr. Quassi de Castro's research primarily investigates nitrogen fertilization techniques, with emphasis on the absorption, assimilation, and redistribution of nitrogen using isotopic techniques (15-Nitrogen). His work examines both foliar and soil application methods and their impact on the soil-plant-environment system. He also studies soil management systems, crop rotation, and the use of biostimulants to mitigate abiotic stresses in sugarcane cultivation.

His recent publications (2023-2024) demonstrate expertise in optimizing fertilizer application, understanding nutrient dynamics in sugarcane systems, and developing sustainable agricultural practices. His research spans plant nutrition, soil science, and agricultural engineering with particular focus on improving nutrient use efficiency in tropical crops.

Scientific Recognition:

• Scholarship from São Paulo Research Foundation (FAPESP)
• PIBIT/CNPq scholarship (2011-2012)
• FAPESP scholarship (2012-2014)
• Participation in research grants supported by FAPESP, CNPq, and Agrisus Foundation

Dr. Quassi de Castro has guided students in specialization courses in 'Soils and plant nutrition' and 'Plant physiology, nutrition, and plant development' since 2017 through SolloAgro (University of São Paulo). His research has practical applications for improving sugarcane production systems while addressing environmental concerns related to fertilizer use.
