INORGANIC FERTILIZERS

Macro-nutrients. Nitrogen.

By the end of the lesson, the learner should be able to:



To identify plants macronutrients.
To classify macro-nutrients as fertilizers and liming elements.


To identify role of nitrogen in plants.
To state symptoms of nitrogen deficiency in plants

List down macro- elements.
Q/A: Definition of an ion; expose ionic form of elements.

Discuss, giving examples the role of nitrogen and the deficiency symptoms.
