TOP-DRESSING PASTURES.
Mr. P. W. Smallfield, Fields Superintendent, Auckland, says •.-"There are a number of phosphatie fertilisers used for top-dressing—the principal ones being superphosphate, slag , and rock phosphates. For general Waikato conditions, superphosphate is probably the most satisfactory fertiliser. The average soil is light and on light soils the response from slag and rock sulphate is not as quick as- it is on heavy soils. Superphosphate is quick in action and when applied in March or April it produces a flush of grass while the weather conditions arc suitable and early autumn topdressing with super is important for securing an increased winter growth of grass. On pastures that are not in good condition and where fog and weeds are present to a considerable extent, super may bring on a rank growth of log, which is neglected by stock and on such land slag or a mixture of slag and super would he preferable so as to encourage a good, white clover growth. On the heavy lands of North Auckland, where (he primary aim is pasture improvement rather than the quick stimulation of grass, slag is probably the most efficient fertiliser to use.
