" Prove all things; hold fast that which is ; lOMMERCIAL fertilizers are coming more and more in general use with market gardeners, and are now quite extensively substituted for stable manure—and that not without good reason. If we examine a good average high-grade com- mercial fertilizer, analyzing 5 per cent, available nitrogen, 6 per cent, phosphoric acid, and 8 per cent, potash, we will find that one ton of it con- tains, besides less valuable ingredients : 100 lbs. nitrogen, at 18 cents, - - • - $18 00 120 '* phosphoric acid, at 8 cents, - - 9 60 160 '* potash, at 5 cents, - - - - 8 00. Total, - $SS 60 Such a^ertilizer probably retails at Mo or $4^ P^^ ^^n, and is fully worth it. All this large amount of plant food, and per- haps one-half more, can be drawn in a single load, while it will take ten such loads of stable manure to supply the same amount of nitrogen (and that in a far less available condition), sixteen such loads to supply the same amount of potash, and thirty to supply the same amount of phosphoric acid. In an average, therefore, the substitution of the commercial fertilizer for barn- yard manure will save 14-15 of the labor and expense in hauling and in application, besides all the additional trouble and labor of composting. In a further comparison of the two manures we come to the following results: A moderately liberal application of compost requires 50 tons to the acre. This means the application of 400 lbs. of nitrogen, 500 lbs. of potash, and 200 lbs. of phosphoric acid, at a cost of $100 to ;gi 25, not taking in consideration the large expense of handling and applying it. Men most liberal in the use of commercial fertilizers apply, and recommend to use, one ton per acre, at a cost of less than (34) Manures for the.
