    Introduction

    Introduce the lesson by briefly explaining to the learners the content of the topics the mode of coverage of the topic and the objectives to be achieved by the end of the chapter coverage..

    Lesson development

    Step 1

    Describing the broad categories of the plant nutrients;

    Introduction

    • Plant nutrients occur in the soil in form of soluble substances.
    • These substances are taken in by the plants in different quantities depending on their roles in the plant tissues.

    Essential Elements

    • These are nutrients needed by plants for various uses.
    • They are divided into two broad categories namely:

    Ø  Macronutrients

    Ø  micronutrients

    Step 2

    Naming the major nutrients required by the plants;

    Macro-nutrients

    ·         These are also referred to as major nutrients.

    ·         They are required by the plant in large quantities.

    They include;

    • carbon,
    • hydrogen,
    • oxygen,
    • nitrogen,
    • phophorus,
    • potassium,
    • sulphur,
    • calcium
    • magnesium

    Step 3

    Discussing the fertilizer elements and the liming elements required by the plants;

    • nitrogen
    • phosphorus
    • potassium

    Conclusion

    Review the lesson by briefly explaining the main categories of the plants nutrients, naming the major nutrients by the plants and the fertilizer elements and the liming elements required by the plants.

    Introduction

    Introduce the lesson by briefly explaining the main categories of the plants nutrients, naming the major nutrients by the plants and the fertilizer elements and the liming elements required by the plants.

    Lesson development

    Step 1

    Explaining the forms in which nitrogen occurs;

    Nitrogen.( N03, NH4+)

    Its sources are; artificial fertilizers, organic matter and atmospheric fixation by lightning and nitrogen fixing bacteria.

    Step 2

    Discussing he role of nitrogen in plants;

    Role of nitrogen in plants

    1.        Chlorophyll formation making the plant succulent deep green in colour.

    2.        Encourages vegetative growth especially in crops where leaves are harvested e.g. kales, Cabbages and pasture grasses.

    3.        Protein formation and protoplasm of all living cells.

    4.        Regulates the availability of phosphorous and potassium in plants.

    5.        Increases the size of grain cereals and their protein content.

    Step 3

    Escribing the nitrogen deficiency symptoms in plants;

    Deficiency symptoms

    1.        Chlorosis or yellowing of the leaves.

    2.        Production of anthocyanin pigment instead of chlorophyll in tomatoes causing purplish colour.

    3.        Stunted growth where plants become dwarfed with extremely short roots.

    4.        Premature leaf fall.

    5.        Premature ripening of fruits.

    6.        Production of light seeds.

    Effects of excess nitrogen

    1.        Scorching of the leaves.

    2.        Delayed maturity.

    3.        Excessive succulence in stems hence fall/lodging.

    Loss of nitrogen from the soil

    1.        Soil erosion

    2.        Leaching

    3.        Volatilization

    4.        Crop uptake

    5.        Used by microorganisms

    Conclusion

    Review the lesson by briefly describing the forms in which oxygen exists in the soil, the role of nitrogen in the soil, symptoms of the nitrogen deficiency and the ways through which nitrogen is lost in the soil
