Red phosphorus, uncatalysed or catalysed with 2% copper (w/w), was compared with superphosphate as a fertiliser.Results showed;-(a) That the addition of uncatalysed red phosphorus to superphosphate did not prolong the fertilising effect of the mixture beyond that of superphosphate itself; (b) That red phosphorus was about 20-30% as effective as superphosphate when uncatalysed and 60% as effective when copper-catalysed.

UNDER the usual management system, pasture surpluses are converted into fodder for feeding in periods of shortage, and sheep or cattle are grazed on pastures most of the year. It is this type of management which influences the present evaluation of pasture species. Whether this outlook is to continue is debatable, but it can be said that the potential production of many species is rarely achieved in practice.

The milk production conditions on 44 farms (18 designated and 26 non‐designated) have been assessed by score‐card marks for visual conditions, facilities, equipment, and methods. Over a period of one year fortnightly samples from these farms were subjected to routine resazurin tests and laboratory pasteurized counts. The results were compared with the total score‐card marks and the equipment assessments of the farms. It was found that neither test alone sufficed to detect unsatisfactory production, but failure on the two tests combined agreed well with the production conditions and facilities. The relation of season and mean shade atmospheric temperature to the thermoduric bacterial content of the milk was studied but no clear association was observed.
