GREEN MANURING.
RECLAMATION OF SWAMP LAND
An instructive demonstration i r the reclamation of swamp land is to be seen at the Ruakura Farm of Instruction. A field of 5 acres of burnt-out swamp land —one of the poorest patches on the property —recently drained was sown to horse beans. The land had been limed and manured • with basic slag and bonedust, i%c\vl. of each, followed by a subsequent top-dressing of 3cwt. of supe'rphosphates. Two small plots had additional dressings, one of 2cwt of kainit and the other of 40Ib of sulphate of ammonia. The crop of beans was a good one, particularly so on the better portions, but apparently the potassic and nitrogenous dressings had no beneficial effect. The bacterial nodules on the roots were very pronounced. To provide the desired humus the beans were ploughed under. Judging by past experience of reclaimed swamp lands at Ruakura, this double green manuring is required to give the required heart to the soil and to render it fit for effective use.
