Scenario: You are a volunteer at a community garden. The soil has become depleted and lacks nutrients. You want to improve the soil quality using composting.
Task: Explain how bacilli contribute to composting and describe the conditions that promote their activity.
Exercice Correction:
Bacilli play a vital role in composting by breaking down organic materials like plant debris, food scraps, and leaves. They act as decomposers, converting complex organic molecules into simpler substances that enrich the soil. These substances include nutrients like nitrogen, phosphorus, and potassium, which are essential for plant growth.
To promote the activity of beneficial bacilli in compost, the following conditions are crucial:
By understanding these factors and creating the optimal conditions for beneficial bacilli, you can effectively improve the soil quality in your community garden through composting.
