“But will not the manure,” asked the Deacon, “injure the quality of the potatoes?”
I think not. So far as my experiments and experience go, the judicious use of good manure, on dry land, favors the perfect maturity of the tubers and the formation of starch. I never manured potatoes so highly as I did last year (1877), and never had potatoes of such high quality. They cook white, dry, and mealy. We made furrows two and a half feet apart, and spread rich, well-rotted manure in the furrows, and planted the potatoes on top of the manure, and covered them with a plow. In our climate, I am inclined to think, it would be better to apply the manure to the land for potatoes the autumn previous. If sod land, spread the manure on the surface, and let it lie exposed all winter. If stubble land, plow it in the fall, and then spread the manure in the fall or winter, and plow it under in the spring.

WHAT CROPS SHOULD MANURE BE APPLIED TO.
“It will not do any harm on any crop,” said the Deacon, “but on my farm it seems to be most convenient to draw it out in the winter or spring, and plow it under for corn. I do not know any farmer except you who uses it on potatoes.”
My own rule is to apply manure to those crops which require the most labor per acre. But I am well aware that this rule will have many exceptions. For instance, it will often pay well to use manure on barley, and yet barley requires far less labor than corn or potatoes.
People who let out, and those who work farms “on shares” seldom understand this matter clearly. I knew a farmer, who last year let out a field of good land, that had been in corn the previous year, to a man to sow to barley, and afterwards to wheat on “the halves.” Another part of the farm was taken by a man to plant corn and potatoes on similar terms, and another man put in several acres of cabbage, beets, carrots, and onions on halves. It never seemed to occur to either of them that the conditions were unequal. The expense of digging and harvesting the potato-crop alone was greater than the whole cost of the barley-crop; while, after the barley was off, the land was plowed once, harrowed, and sowed to winter wheat; and nothing more has to be done to it until the next harvest. With the garden crops, the difference is even still more striking. The labor expended on one acre of onions or carrots would put in and harvest a ten-acre field of barley. If the tenant gets pay for his labor, the landlord would get say $5 an acre for his barley land, and $50 for his carrot and onion land. I am pretty sure the tenants did not see the matter in this light, nor the farmer either.
Crops which require a large amount of labor can only be grown on very rich land. Our successful market-gardeners, seed-growers, and nurserymen understand this matter. They must get great crops or they cannot pay their labor bill. And the principle is applicable to ordinary farm crops. Some of them require much more labor than others, and should never be grown unless the land is capable of producing a maximum yield per acre, or a close approximation to it. As a rule, the least-paying crops are those which require the least labor per acre. Farmers are afraid to expend much money for labor. They are wise in this, unless all the conditions are favorable. But when they have land in a high state of cultivation—drained, clean, mellow, and rich—it would usually pay them well to grow crops which require the most labor.
