THE EFFECT OF PHOSPHATI MANURES.
AN EXPERT OPINION. \ A farmer recently wrote to the Victorinn Department of Agriculture asking to be informed whether long-continued application of artificial fertilisers in connection with wheat growing injuriously affected the soil, even when tho land was cropped only every third year. The reply furnished was follows:— "The continued application of phosphates to wheat growing land will not injuriously affect the soil. What will happen is: That -if the amount of phosphate acid applied be continually in excess of the requirements of the crop the phosphoric acid will, accumulate until a point irf reached when further applications-, will .cease to ho profitable. The soil will then -he. comparatively rich in phosphoric acid, but may bo deficient in nitrates or in potash, in which care the money invested in phosphates will be mora profitably employed in adding these other deficient elements. In any cap?, the intelligent. farmer should occasionally test his laud by means of small experimental plots to find just what the soil' requirements are."-
