As a member of the Study Group on Sustainable Agriculture (GEAS), Alexandre Caique Costa e Silva has a passion for using science as a way to identify and develop environmental farming practices and technology.


Over the course of his work as an Agronomy graduate student at the Instituto Federal do Ceará in northeastern Brazil, Silva has focused on the physiological responses that crops have to various ecological fertilization methods, such as green manuring. Using instruments like CI-600 In-Situ Root Imager and CI-203 Handheld Laser Leaf Area Meter, Silva is observing the impacts these different treatments have on plant growth over time.


In 2014, Silva began working with Professor Natanael Pereira to conduct research on “Magnum” watermelons, which had received a treatment of phosphate fertilizer, by observing root characteristics with a minirhizotron system. For this study, Silva installed ten, 60 centimeter transparent tubes in red clay soil in Brazil. After three to four weeks, ten total treatments were applied to each sample.


Using the CI-600, Silva and his team took non-destructive images of each crops’ roots and observed that the root length density differed depending on the combination of doses and forms of phosphate fertilization that was applied.
