Nutritious Nitrogen

Accessibility for educational games is a work in progress across the industry. We continually seek solutions to make our products fully accessible, and we strive to adhere to established standards for accessibility and usability on each new project. Some of our older products may not be accessible in all areas and have not been optimized for current accessibility recommendations. Here, we offer the content and approach of this game, so that learners are better able to find alternative content and ways of learning.

Content of the module

Nutritious Nitrogen helps students explores the relationship of nitrogen integration to cattle and plant health and productivity. In two different modules, students can practice creating feed rations for animals and fertilizer regimes for plant fields and understanding how the chemistry of nitrogen relates to how animals, plants, and the environment metabolize these feeds and fertilizers over time.


Rather than relying on accuracy and speed, these modules focus on subject comprehension and do not contain timed exercises. Students can use the modules as a study tool to review a troublesome concept, or explore a new concept at their own pace. These interactions require some mouse clicking and minimal dragging.
