Business / Agriculture / Fertilizer: Any organic or inorganic material, either natural or synthetic, used to supply elements (such as nitrogen (N), phosphate (P2O5), and potash (K2O)) essential for plant growth. If used in excess or attached to eroding soil, fertilizers can become a source of water pollution.
Entertainment / Golf / Divot Mix: (also 'sand and seed') a combination of sand, soil and grass seed (and perhaps even fertilizer in some cases) used to fill in divots, optionally dyed green to blend more closely with the color of the MORE
