SULPHATE OF IRON.
On the 6th October last a quarter of an acre on the face 'of the Big Hill pasture at Ruakura Farm of Instruction was top-dressed with sulphate of iron at the rate of 1 cwt. per acre. As far as the eye can judge, the dressing has been beneficial, and at the present moment the plot is a brighter green than any other portion of the paddock. The growth of clover has been stimulated, and moss, which is prevalent on adjoining portions of the paddock, has to some extent been eradicated. On the other hand, sulphate of iron applied alone (with the seed) to a plot sown with rape-seed at the same rate per acre as above caused an entire failure of germination.
As the amount of sulphate of iron required by plants is exceedingly small, it is difficult to account for the beneficial results obtained in the pasture land, unless that it may be of benefit as a fungicide. A portion of No. 4 paddock (also pasture) was top-dressed on 25th February last, and this will be carefully watched.
