Student User Guide
Build a compost pile and monitor its performance while learning what to look for to determine the health of your compost.
Key Concepts
As a student you will gain practical experience through hands-on team activities, including a compost pile build with field tests to learn how to measure and read key performance indicators of compost health.
AEYD is the tool for logging your team data and viewing compost pile performance. After your teams recipe and measurement data has been successfully submitted, your dashboard will display your teams measurement results aka performance. NOTE: These performance visualizations are interactive, by hovering your pointer over a visualization a tooltip will appear and provide details about that point.
Getting Started
Logging In
Team Scribes can log in using the email/password combination provided by your instructor.
NOTE: Please treat the email/password credentials as sensitive information and do not share, save or post where they might be compromised.

Manage Your Team Name
Your team name can be updated by clicking on pencil icon to the right of your team name.
Manage Your Team Recipe
The recipe tool is used for calculating the Carbon to Nitrogen ratio (C:N), Moisture, and Bulk Density on an analysis of feedstocks and proportions of a given Recipe.
Edit Recipe
Click on the edit recipe button to update your recipe feedstock composition.
Your recipe feedstocks have been added in your Mix. Update parts by clicking on the pencil icon. View feedstock calculations and recipe results above the list of selected ingredients.
Logging Measurements
Add Measurement
Click on the add measurement button:
Select from two types of manual logs:
Training Daily Measurement
This measurement (or manual log) captures daily field testing of temperature and oxygen for training at (4) orientations: Lower Edge, Lower Middle, Upper Edge, Upper Middle.
Training One-Time Measurement
This measurement (or manual log) captures lab test results and one-time recipe mix field test calculations; these measurements are only taken once during the course:
Hand Squeeze Moisture
Bulk Density Field Test
Free Air Space Field Test
Oven Dryer Moisture
Edit Measurement
To modify an existing measurement, click on the edit measurement button, select measurement and modify.
View Your Performance
Once measurements have been successfully submitted you will begin to see results visualized on your dashboard. All visualizations are interactive and allow you to explore the data you’ve entered.
Recipe Mix
Results of your recipe feedstock mix is visualized in this section.
Feedstock Distribution
Stacked bar chart of feedstock distribution in percent where the recipe is 100%, feedstocks are listed in alphabetical order. Hovering over a feedstock part will show parts in a tooltip.
Water
Bar chart of gallons of water in your recipe.
Recipe Mix Results & Field Tests
Results from your recipe feedstock mix calculation as well as recipe field tests are visualized in this section.
Bulk Density
Bar chart of recipe feedstock mix calculation results and field test results.
Target: 700 - 1,000 lb/cubic yard
C:N
Bar chart of recipe feedstock mix calculation results where N=1.
Target: 20:1 - 40:1
Free Air Space
