Effect of Microgravity on Nitrogen Fixation in Red Clover Study
Investigating the impact of microgravity on nitrogen fixation in red clover at Johnson County Central High School in Tecumseh, NE. The experiment aims to determine if clover exposed to space conditions fixates nitrogen similar to Earth conditions, crucial for growing food in space. Hypothesis, experiment setup, materials used, and initial research findings are presented, along with acknowledgments to sponsors and a call for questions.

Abstract In order to grow our own food in space we need fertile soil. Red clover is a legume that uses bacteria in the soil to naturally fixate nitrogen, making the soil fertile. In this experiment we planted both our sample and control, and will compare how much nitrogen is added to the soil by the clover.
Hypothesis We believe that the clover exposed to microgravity will release the same quantities of nitrates as it would on Earth.
Experiment Our experiment allowed the seeds to germinate in space. The clamps were opened on U-2. The seeds were planted upon return to JCC, and the nitrogen content will be tested throughout its life cycle. Materials: Cotton, Soil (Contains Proteobacteria), Red Clover (Trifolium pratense L), Water
