POTASH AND POTATOES.
For the past five year?, at an agricultural station in Germany, plots have been arranged no which potatoes have always received dressings of farmyard manure, and other plots on which no farmyard manure has been applied but suitable quantities of mineral fertilisers, phosphoric acid with potash, and potash alone, in order to compare the different results, although as it is pointed out, potatoes, in regular farming practice, are seldom grown without the help of farmyard manure, or only moderate dressings of it, is used, it is essential to apply potash, and that the effect of omitting this constituent is more felt by the crop than the omission of either nitrogen or phosphoic acid. The experimenter concludes his report with the remark that the results obtained by his rivals serve to confirm previous experience that the potato crop is particularly grateful for liberal supplies of readily available potash. If kainit is used it should be applied quite early, -even in the autumn or winter. There is no fear of loss of potash, and by being put in the soil in good time, the potash is ready to be taken up by the plant, and the salt in the kainit has lost the power of acting with detriment on the qulity of the crop, a3 it sometimes does if applied when the potatoes are put in the ground.
