Hi there, young learners! Welcome back to Primary 2 Pre-Vocational Studies, Agricultural Science. In our previous lesson, we learned about the damages caused by harmful insects. Today, we’re going to learn about Farmers’ Friends.
Objectives
By the end of this lesson, you should be able to:
Define the term “farmers’ friends.” Appreciate the role of earthworms in agriculture. Discuss the benefits of earthworms in a group.
Farmers’ Friends; Usefulness Of Earthworms
Farmers’ Friends are organisms that help farmers by improving soil health, controlling pests, or pollinating plants. Earthworms are often called farmers’ friends because they provide many benefits to the soil and plants.
What are Earthworms?
Earthworms are small, segmented creatures that live in the soil. They are important for the health of the soil and the growth of plants.
Usefulness of Earthworms
There are many ways that earthworms help farmers, some of these include:
Soil Aeration: Earthworms create tunnels in the soil, which allow air to reach plant roots. This helps the roots to breathe and grow stronger. Nutrient Recycling: Earthworms break down organic matter, such as dead leaves and plant roots, releasing nutrients back into the soil. These nutrients are then available for plants to use. Improved Soil Structure: Their movements mix the soil, making it more fertile and easier for plants to grow. This also helps to prevent soil erosion. Water Infiltration: The tunnels made by earthworms help water to penetrate the soil more effectively. This helps to prevent flooding and drought. Plant Growth: Healthy soil with earthworms supports better plant growth. This means that farmers can grow more food and make more money.
Lesson Evaluation
Now that you’ve learned about Farmers’ Friends, let’s see if you can answer these questions:
- What are farmers’ friends?
- What are three ways that earthworms are useful to farmers?
- How do earthworms improve soil structure?
- Why are earthworms important for water infiltration in soil?
- Can you think of any other ways that earthworms help farmers?
Conclusions or Summary
Today, we learned about the importance of earthworms as farmers’ friends. They play a vital role in improving soil health and supporting plant growth. Remember, taking care of the environment and understanding the interconnectedness of living organisms is crucial for sustainable agriculture.
