Pit A
Pit B
Fruit and vegetable peels mixed with dried leaves.
The same waste, with no dried leaves.
More plant waste for microbes to act on.
Less plant waste for microbes to act on.
Decomposes faster into dark, rich manure.
Decomposes more slowly.
She is testing how the waste decomposes into manure, and whether adding dried leaves changes the result.
Explanation
- Microbes in the soil decompose the buried waste into manure.
- Pit A has peels mixed with dried leaves; pit B has peels only.
- She compares the two pits to see how decomposition differs.
- This tests how well microbes turn the waste into manure.
She is testing decomposition of waste into manure by soil microbes.
