“That is a capital letter,” said the Deacon. “It is right to the point, and no nonsense about it.”
“He must make a good deal of manure,” said the Doctor, “to be able to use 40 loads to the acre on his meadows and pastures once in three years, and the same quantity every year on his field of mangel-wurzel.”
“That is precisely what I have been contending for,” I replied; “the dairymen can make large quantities of manure if they make an effort to do it, and their farms ought to be constantly improving. Two crops of hay on the same meadow, each year, will enable a farmer to keep a large herd of cows, and make a great quantity of manure—and when you have once got the manure, there is no difficulty in keeping up and increasing the productiveness of the land.”
HOW TO MAKE MORE AND BETTER MANURE ON DAIRY FARMS.
“You are right,” said the Doctor, “in saying that there is no difficulty in keeping up and increasing the productiveness of our dairy farms, when you have once got plenty of manure—but the difficulty is to get a good supply of manure to start with.”
This is true, and it is comparatively slow work to bring up a farm, unless you have plenty of capital and can buy all the artificial manure you want. By the free use of artificial manures, you could make a farm very productive in one or two years. But the slower and cheaper method will be the one adopted by most of our young and intelligent dairymen. Few of us are born with silver spoons in our mouths. We have to earn our money before we can spend it, and we are none the worse for the discipline.
Suppose a young man has a farm of 100 acres, devoted principally to dairying. Some of the land lies on a creek or river, while other portions are higher and drier. In the spring of the year, a stream of water runs through a part of the farm from the adjoining hills down to the creek or river. The farm now supports ten head of cows, three horses, half a dozen sheep, and a few pigs. The land is worth $75 per acre, but does not pay the interest on half that sum. It is getting worse instead of better. Weeds are multiplying, and the more valuable grasses are dying out. What is to be done?
In the first place, let it be distinctly understood that the land is not exhausted. As I have before said, the productiveness of a farm does not depend so much on the absolute amount of plant-food which the soil contains, as on the amount of plant-food which is immediately available for the use of the plants. An acre of land that produces half a ton of hay, may contain as much plant-food as an acre that produces three tons of hay. In the one case the plant-food is locked up in such a form that the crops cannot absorb it, while in the other it is in an available condition. I have no doubt there are fields on the farm I am alluding to, that contain 3,000 lbs. of nitrogen, and an equal amount of phosphoric acid, per acre, in the first six inches of the surface soil. This is as much nitrogen as is contained in 100 tons of meadow-hay, and more phosphoric acid than is contained in 350 tons of meadow-hay. These are the two ingredients on which the fertility of our farms mainly depend. And yet there are soils containing this quantity of plant-food that do not produce more than half a ton of hay per acre.
In some fields, or parts of fields, the land is wet and the plants cannot take up the food, even while an abundance of it is within reach. The remedy in this case is under-draining. On other fields, the plant-food is locked up in insoluble combinations. In this case we must plow up the soil, pulverize it, and expose it to the oxygen of the atmosphere. We must treat the soil as my mother used to tell me to treat my coffee, when I complained that it was not sweet enough. “I put plenty of sugar in,” she said, “and if you will stir it up, the coffee will be sweeter.” The sugar lay undissolved at the bottom of the cup; and so it is with many of our soils. There is plenty of plant-food in them, but it needs stirring up. They contain, it may be, 3,000 lbs. of nitrogen, and other plant-food in still greater proportion, and we are only getting a crop that contains 18 lbs. of nitrogen a year, and of this probably the rain supplies 9 lbs. Let us stir up the soil and see if we cannot set 100 lbs. of this 3,000 lbs. of nitrogen free, and get three tons of hay per acre instead of half a ton. There are men who own a large amount of valuable property in vacant city lots, who do not get enough from them to pay their taxes. If they would sell half of them, and put buildings on the other half, they might soon have a handsome income. And so it is with many farmers. They have the elements of 100 tons of hay lying dormant in every acre of their land, while they are content to receive half a ton a year. They have property enough, but it is unproductive, while they pay high taxes for the privilege of holding it, and high wages for the pleasure of boarding two or three hired men.
