Legumes Fix Nitrogen
Project Type: Technology
Research how legumes “fix” nitrogen and why crop rotation keeps farm land more productive.
Design a flow chart about nitrogen fixation to include:
- Nitrogen fixing legumes and their bacteria
- Atmospheric nitrogen
- Fixed nitrogen
Write 1-2 page(s) on why crop rotation keeps farm land more productive
The following are site to help understand the nitrogen cycle and research crop rotation. Students may use these and or any other site they find.
Type in “nitrogen cycle” or “crop rotation”
