Mixing Fertilizers

Míiny opinious aro expressed on the advisability of farmers mixiug their own fertilizers. Hero is what American Cultivator says on the subject: There is now so much oompetition in making ferfilizers that they are genersily sold even at retail at very near cost, and generally much cheaper than farmers oau buy the materials and mix them. Some of the largest phosphate faetories turn off the superphósphatc as a by prodnet, getting the maiu part of . their proiit from the articles into which the boiie has been manufactured. Even the very smallest pieoes of bone are not made directly into superphosphate. They are first nsed af ter burning to remove the impurities from sugar. It is i evident that no farmer who gathers boncs in the ueighborhood and tries to work them np iuto superphosphate can . compete with establishments that first make two or three profits from the bone, and then from the refuse make with less expense than the farmer can do the fertilizer that bis grain and grass erop ! needs. We once tried dissolving broken pieces of bone and cattle horns in sulphuric acid, but got only a sticky mess, which it was impossible to dry or get J fine enoagh fo be drilled. We flnally put the heap in compost with some yard manure, and afterit had uil rotted down we distributed it as thinly as we conld with a shovel from a wagon, but then could not make a wagon load cover one-quarter the ground thitt the same amount of fertilizer would have prepared to produce a heavy wheat erop and good clover erop following it.
