FARMERS' COLUMN. 1 THE ECONOMY OF ARTIFICIAL MANURING. [The following paper (copied from the Agricultural Gazette) was resd by Mr Charles Gay Roberts, at a meeting of the Agricultural and Horticultural Co-operative Association, at their rooms, 47, Milbank Street, Westminster, on Monday—Mr Thomas Hughes.M.P., in the chair.] (Continued from last week.) In applying a dressing of 2 cwt. per acre, each pound of the manure requires to be spread evenly over an area of twenty one square yards; it will be obviously impossible to do this if the manure is damp or lumpy. Hence we some- times find that a superphosphate proved by analysis to be of very high quality, but badly sent out, will sometimes give results in the field inferior to those obtained from a thoroughly well prepared but poorer superphosphate. It*is specially needful to sif; out and crush all the small lumps found in Peruvian euano, for these contain the most valuable constituents. If there is any difficulty in reducing them, the addition of a little sharp sand will prevent their caking together. To ensure their even distribution, guano, nitrate of soda, and other concentrated manures should be mixed with two or three timf s their weight of ashes or dry earth. Sometimes guano so diluted may be found too dry it is then advisable to add about a bushel per acre of common salt, which, by its moisture, will prevent the fine guano dust being blown away bv the wind in sowing. Having paid special attention to this point in conducting field exp:riments, I find it a great advantage in sowing by hand to have the diluting substance differ greatly in colour from the soil. I have lately used a bright red dust collected in a brickyard and well sifted. It serves as an excellent tell-tale, and shows at once to the eye whether the manure has been sown evenly or not. On dark-coloured soils a mixture of gypsum and salt would similarly give a strong contrast, the gypsum being very dry and the salt moist: the proportions should be regulated to it the condition of tha manure that is to be diluted with the mixture. In ordinary practice we drill the manure with the seed for root crops, and apply it broadcast for corn crops. When a full dressing of anarnoniacal manure is sown with wheat there is an apparent loss, for only a part of the nitrogen is taken up by the crop. In the hope of preventing this loss, Mr Lawes is now trying the experiment of drilling the manure with the seed his results are not as yet sufficiently conclusive to make us depart from our usual custom of sowing the manure broadcast, and wo may, perhaps, better effect the saving by giving two or three small dressings instead of a single heavy one. In applying a small dressing for Swedes or Mangels, it is, no doubt, most economical to place it under the seed, for with drills two feet apart it is long before the young plants can draw much nourishment from what falls between them. If the land is in b-.gb condition, we only need the artificial to start the young plant, and when its roots are well formed they will find enough food further off to sustain their growth. On the other hand, with land in poor condition, it is not, I think, good policy to place the whole of a heavy dressing immediately beneath the seed, for in a dry season the seed will not germinate well if much guano, superphosphate, or potash salt are in almost immediate contact with it; we shall obtain a more even growth by applying one-half of the manure with the drill, and the rest broadcast. If nitrate of soda is used, the second half dressing may be reserved till the plants are set out by the hoe. For dispersing the manure evenly the water drill has some advantage over the dry drill, and great benefit has been derived from its use on farms in the Fens, where water can be obtained in the field without carting. It has not, how- ever, come into general use. and is not, perhaps, to be recom- mended where the water must be fetched from a distance. I have not had any personal experience with water-drills, but the subject is interesting, and I hope that those gentle- men present who may have used them will give us the results of their experience. (To be continual.)
