## Abstract In a field experiment where sulphate of ammonia was applied in April at 0, 2, 4, 6, 8 and 12 cwt. per acre to three grass mixtures which were cut for silage in early June, the nitrate‐N content of the herbage was detectable at the 4‐cwt. level and considerable at the 12‐cwt. level. A cl
