Published online by Cambridge University Press: 27 March 2009
Extract
Ammonium nitrate and ammonium sulphate wore compared as top-dressing applications in thirty-six field experiments on winter wheat and eighty-nine on grassland in various parts of Great Britain in 1956-62. The rates of application were 35-60 lb./acre of nitrogen for winter wheat and 30-100 lb./acre for grassland in one application only.
