Two University of Alberta researchers have published a
step by step plan to one-day end the use of environmentally harmful
chemicals on commercial crops by developing plants that produce their
own fertilizer.
U of A plant biologist Allen Good says the energy required to produce
nitrogen fertilizers has pushed the world-wide cost for agricultural
producers to a $100 billion a year. Good says that while they are
necessary for high yields, those nitrogen fertilizers also damage the
environment. Emissions from nitrogen fertilizers add to greenhouse gas
emissions and chemical run-off from farm fields cause algae blooms in
fresh water lakes and rivers. Good says the cost of cleaning up the
environment adds another $50 billion to the world-wide cost of
commercial agriculture fertilizers.
Good and his U of A co-author Perrin Beatty says some plants, like
peas, have the natural ability to split atoms of nitrogen gas and use
the bioactive elements that enhance growth. Mass produced and consumed
cereal crops like wheat, rice and maize cannot naturally split nitrogen
atoms and need commercial fertilizers. Fertilizer producers use huge
amounts of natural gas to to split nitrogen atoms to supply its
bioactive components that are then spread on fields in the form of a
chemical .
Good and his U of A co-author Perrin Beatty say the fix is to
genetically alter agricultural products like cereal crops so they can
process nitrogen from the atmosphere naturally and still get the same
growth enhancing effect as commercial fertilizers.
