Successful, high-yield crop production often depends on the application of fertilizers
to ensure that the correct quantity of nutrients is available to plants during the
growth cycle. Excess amounts of some nutrients can also be detrimental to plant
health, therefore monitoring the quantity of nutrients in fertilizers is essential. Elemental analysis techniques provide valuable information on fertilizer quality. This
information helps to determine the correct quantity of fertilizer to apply to satisfy
the nutrient requirements necessary for optimal crop yield.
