F335 STORYLINES NOTES

AGRICULTURE AND INDUSTRY

1. Growing one crop multiple times on the same soil can destroy the soil's fertility by
depleting specific nutrients. Agricultural technology appropriate for one place may
not be suitable for another because of differences in growing conditions and soil
types. Sustainable farming is…

nitrate(V) ammonium sulfate and ammonium phosphate. Some ammonia is used in
the fermentation industry to adjust pH.
8. Pesticides (insectides, herbicides, fungicides) kill insects that eat our crops,
weeds that compete with the crops for soil nutrients, and moulds that rot plants and
seeds. Some are banned, e.g. DDT,…

6. A paint is usually made up of two main parts: the colouring matter (pigment) and the

evaporation is high, the sea is saltier. Salt was used to preserve food before
refrigerators and freezers were invented.
3. Underneath the sediments of the ocean floor are lavas, generated by long, thin
underwater ridges. Lava and gases high in chlorine, bromine and sulfur compounds
