19. FERTILIZER COMPUTATION
• To supply a certain amount of plant nutrients, determine the amount of fertilizer to
be applied per hectare based on thee composition of the fertilizer materials to be
used.
• Fertilizer grade or analysis refers to the MINIMUM GUARANTEE of the NUTRIENT
CONTENT IN TERMS OF PERCENT TOTAL N, PERCENT AVAILABLE P202, AND
PERCENT WATER SOLUBLE K2O in a fertilizer.

20. EXAMPLE
• Ammonium sulfate
21 kg of N

the set containing
all elements being
considered or
studied. It is
usually denoted by
∪.
The empty set,
denoted by { } or ∅,
is a set that
does not contain
any element. It
is also known as
the null set.
