I have a strong impression that most farmers can do better at making and saving fertilizers than by buying them. Lime and Sulphur (Gypsum), if your soil lacks them, you must buy; but a good farmer who keeps even a span of horses, three or four cows, as many pigs, and a score of fowls, can make for $100 fertilizers which I would rather have than two tuns of Guano, costing him $180 to $200. If he has a patch of bog or a miry pond on his farm – any place where frogs will live – he can dig thence, in the dryest time next Fall, two or three hundred loads of Muck, which, having been left to dry on the nearest high ground till November or later, and then drawn up and dumped into his barn-yard, pig-pen, and fowl-house, will be ready to come out next Spring in season for corn-planting, and, being liberally applied, will do as much for his crop as two tons of Guano would, and will strengthen his land far more. If he has no Muck, and no neighbor who can spare it as well as not, let him at midsummer cut all the weeds growing on and around his farm, and in the Fall gather all the leaves that can be impounded, using these as litter for his cattle and beds for his pigs, and he will be agreeably surprised at the bulk of his heap next Spring.
I am an intense believer in Home Production. We send ten thousand miles for Guano, and suffer the equally valuable excretions of our cities to run to waste in rivers and bays, poisoning or driving away the fish, and filling the air with stench and pestilence. No farmer ever yet intelligently tried to enrich his land and was defeated by lack of material. He may not be able to do all he would like to at first; but persistent effort cannot be baffled.
11. Shallow culture is the most crying defect of our average farming. Poverty may sometimes excuse it; but the excuse is stretched quite too far. If a farmer has but a poor span of horses, or a light yoke of thin steers, he cannot plow land as it should be plowed; but let him double teams with his neighbor, and plow alternate clays on either farm; or, if this may not be, let him buy or borrow a sub-soil plow, and go once around with his surface plow, then hitch on to the sub-soil, and run another furrow in the bottom of the former. There are a few intervales of rich, mellow soil, deposited by the inundations of countless ages, where shallow culture will answer, because the roots of the plants run freely through fertile earth never yet disturbed by the plow; but these marked and meagre exceptions do not invalidate the truth that nine-tenths of our tillage is neither so deep nor so thorough as it should be. As a rule, the feeding-roots of plants do not run below the bottom of the furrows, though in some instances they do; and he who fancies that five or six inches of soil will, under our fervid suns, with our Summers often rainless for weeks, produce as bounteous and as sure a crop as twelve to eighteen inches, is impervious to fact or reason. He might as sensibly maintain that you could draw as long and as heavily against a deposit in bank of $500 as against one of $1,500.
12. Finally, and as the sum of my convictions, we need more thought, more study, more intellect, infused into our Agriculture, with less blind devotion to a routine which, if ever judicious, has long since ceased to be so. The tillage which a pioneer, fighting single-handed and all but empty-handed with a dense forest of giant trees, which he can do no better than to cut down and burn, found indispensable among their stumps and roots, is not adapted to the altered circumstances of his grandchildren. If our most energetic farmers would abstract ten hours each per week from their incessant drudgery, and devote them to reading and reflection with regard to their noble calling, they would live longer, live to better purpose, and bequeath a better example, with more property, to their children.
My self-imposed task is done. I undertook to tell What I Know of Farming through one brief essay for each week in 1870; and, in the face of multifarious and pressing duties, and in despite of a severe, protracted illness, the work has been prosecuted to completion. Had I not kept ahead of it while in health, there were weeks when I must have left it unaccomplished, as I was too ill to write or even stand.
I close with the avowal of my joyful trust that these essays, slight and imperfect as they are, will incite thousands of young farmers to feel a loftier pride in their calling and take a livelier interest in its improvement, and that many will be induced by them to read abler and better works on Agriculture and the sciences which minister to its efficiency and impel its progress toward a perfection which few as yet have even faintly foreseen.
