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 |
