§ Dr. David ClarkTo ask the Minister of Agriculture, Fisheries and Food whether he is investigating methods of reducing and controlling emissions of ammonia gas from agricultural systems; and if he will make a statement.
§ Mr. RyderYes. Ammonia is released from animal urine and faeces. Research is being done to understand the mechanisms of ammonia release and to devise systems of farm waste treatment and application to land that will minimise volatilisation and losses.
