CONTENT OF THE LESSON

LESSON 1 – INTRODUCTION

Soil fertility is the ability of soil to sustain agricultural plant growth by providing essential plant nutrients.

When the soil loss its fertility, it can support agricultural plants because of burning, leaching, overgrazing, land clearing and erosion.

 

WAYS OF MAKING THE SOIL FERTILE 

 

Soil can be make fertile in the following ways:

1. Adding fertilizer

2. Mulching

3. Crop rotation

4. leaving fallow

5. Afforestation

 

LESSON 2 – HOW TO MAINTAIN SOIL FERTILITY 

1. ADDING FERTILIZER 

Fertilizer is an organic and inorganic materials that is added to the soil to supply plant nutrients.

Organic materials are decayed death plants and animals and their waste products in the environment. While inorganic materials are chemical compound.

 

2. MULCHING 

Mulching is a layer materials that is spread on top of the soil to protect the soil nutrients.

Mulching is very important because,

  • it preserves the soil moisture
  • it improves fertility and and health of the soil
  • it reduces weed growth, and
  • it enhances the visual appeal of the area.

 

3. CROP ROTATION 

 

Crop rotation is the practice of growing different crops on a piece of land at different seasons.

The planting of a particular crop this season will not be planted next season on the same land.

 

4. LAND FALLOW 

Fallow is the practice of leaving agricultural land for about a season or more without planting to naturally recover its nutrients.

 

5. AFFORESTATION 

Afforestation is the planning of new trees across the land without trees.

It is also a common practice that proceed deforestation.

 

ASSIGNMENT

Find out the meaning of compost.

 

LESSON 3 – LESSON SUMMARY AND WEEKLY ASSESSMENT 

 

POST LESSON ACTIVITIES

Make a list of all materials needed for the next lesson and the ones the pupils have to sort out. For example – animals dung, dry leaves, etc.

 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Asks pupils to state why we apply animals compost to the plants.

Pupil’s Activities – State why we apply animals compost to the plants.

3. Relates pupils to respond to one of the ways of improving soil fertility.

4. Displays chart showing ways of improving soil fertility for the pupils to identify and discuss.

 

Pupil’s Activities – Discuss the activities on the chart.

5. Guides pupils to perform experiments on one or two ways to making the soil fertile – fertilizer or manure.

Pupil’s Activities – Participate in carrying out the experiments set up by the teacher.

6. Summary each lesson on the board.

Pupil’s Activities – Copy as the teacher writes.

 

CONCLUSION

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
