Week Eight
Subject: Agricultural Science
Class: Primary Four
Week of the Second Term: 8th Week
Topic: Maintaining Soil Fertility – Mulching
Subtopic: Meaning and Use of Mulching
Instructional Objectives
At the end of the lesson, pupils should be able to:
- Define mulching and explain its importance in maintaining soil fertility.
- Identify different types of mulch and describe how to apply them in a garden.
- Demonstrate the process of applying mulch to a designated area in the school garden.
Entry Behaviour
Pupils should already have a basic understanding of soil fertility and previous lessons on maintaining soil health. They should be familiar with concepts such as fertilizers and the importance of plant growth.
Instructional Materials
- Textbook: Agricultural Science for Primary School Book 4
- Visual aids: Pictures of different types of mulch (e.g., straw, grass clippings, wood chips)
- Samples of mulch materials for demonstration (if available)

Content
Mulching
Mulching is the practice of covering the soil around plants with a layer of material to conserve moisture, improve soil fertility, and suppress weeds.
Importance of Mulching:
- Moisture Retention: Mulch helps to retain moisture in the soil, reducing the need for frequent watering.
- Weed Control: A layer of mulch can block sunlight, which helps to prevent weed growth.
- Soil Temperature Regulation: Mulch keeps the soil cooler in hot weather and warmer in cold weather, creating a more stable environment for plant roots.
- Nutrient Addition: Organic mulches, such as grass clippings or straw, decompose over time and add nutrients to the soil.
