---
**Part 1: Causes of Reduction in Soil Fertility**
**Objective:**
1. To help students understand factors that lead to the reduction of soil fertility.
2. To discuss the importance of maintaining soil fertility.
**Duration:** 45 Minutes
**Materials Needed:**
- Chart paper
- Markers
- Samples of soil (fertile and infertile)
- Pictures or flashcards showing various causes of soil degradation
**Introduction (10 Minutes):**
1. Greeting and attendance.
2. Brief overview of the day's lesson.
3. Ask students, "What do plants need to grow healthy and strong?" Guide the discussion towards the importance of fertile soil.
**Lesson Content:**
1. **Definition of Soil Fertility:**
- What fertile soil is and why it is important for growing crops.
2. **Causes of Reduction in Soil Fertility:**
- **Overcultivation:** Constant growing of crops without giving the soil time to recover can deplete nutrients.
- **Soil Erosion:** Water and wind can remove the top layer of soil which contains most nutrients.
- **Overgrazing:** When too many animals feed on land, they can destroy vegetation and compact the soil.
- **Deforestation:** Cutting down trees can lead to erosion and loss of soil fertility as roots hold the soil in place.
- **Use of Chemical Fertilizers and Pesticides:** Excessive use can harm beneficial organisms and disrupt soil chemistry.
- **Poor Waste Disposal and Pollution:** Dumping waste improperly can lead to contamination of soil.
**Activity (15 Minutes):**
1. Show samples of fertile and infertile soil. Discuss the differences.
2. Use pictures or flashcards to illustrate the causes discussed.
3. Group activity: Divide students into small groups. Give each group chart paper and markers to draw one cause of soil fertility reduction and present it to the class.
**Conclusion (5 Minutes):**
1. Recap the causes.
2. Discuss ways to maintain soil fertility like crop rotation, using compost, and planting cover crops.
3. Open the floor for any questions.
**Assessment:**
- Participation in group activity.
- Ability to identify causes of soil fertility reduction.
