(c) State three methods of applying inorganic fertilizers to the soil. (3 marks)
Observation

However, some candidates were unable to spell correctly ‘annual’ and ‘perennial’ as classes of crops while others wrote ‘living organisms’ instead of ‘organic matter’ as a soil component, thereby losing some marks.
The expected answers include:
