A color picture produced by assigning a color to a particular spectral band. Ordinarily blue is assigned to band 1 or 4 (~ 500 to 600 nm), green to band 2 or 5 (~ 600 to 700 nm), and red to band 3 (~ 700 nm to 1 µm) or 7 (~ 800 nm to 1. 1 µm), to form a picture closely approximating a color-infrared photograph.

A product obtained when phosphate rock is treated with H2SO4, H3PO4, or a mixture of those acids. * ammoniated - A product obtained when superphosphate is treated with NH3 or with solutions containing NH3 and/or other NH4-N containing compounds. * concentrated - Also called triple or treble superphosphate, made with phosphoric acid and usually containing 19 to 21% P (44 to 48% P2O5). * enriched - Superphosphate made with a mixture of sulfuric acid and phosphoric acid. This includes any grade between 10 and 19% P (22% and 44% P2O5), commonly 11 to 13% P (25 to 30% P2O5). * normal - Also called ordinary or single superphosphate. Superphosphate made by reaction of phosphate rock with sulfuric acid, usually containing 7 to 10% P (16 to 22% P2O5). * ordinary - See superphosphate, normal. * single - See superphosphate, normal.
