Fallow lands should be broken up early in summer, as soon as corn planting is over; about midsummer plow again; and the last time early in September to prepare for seed.

A grass or clover lay[4] may be plowed under deeply at

midsummer, and not disturbed till sowing-time; and the fall plowing should not disturb the inverted sod.

When wheat is to be sown on wheat again, as large a part of the straw should be left in the harvest-field as possible. This is to be plowed under; but, if it can be done without endangering the fences, it would be better to burn it over; the ashes will contain all the valuable salts. On this point we extract the following note appended by the editor of Liebig’s Agricultural Chemistry.

“In some parts of the grand-duchy of Hesse, where wood is scarce and dear, it is customary for the common people to club together and build baking-ovens, which are heated with straw instead of wood. The ashes of this straw are carefully collected and sold every year at very high prices. The farmers there have found by experience that the ashes of straw form the very best manure for wheat; although it exerts no influence on the growth of fallow-crops (potatoes or the leguminosæ, for example). The stem of wheat grown in this way possesses an uncommon strength. The cause of the favorable action of these ashes will be apparent, when it is considered that all corn-plants require silicate of potash; and that the ashes of straw consist almost entirely of this compound.”

But this procedure does not depend upon theoretical reasonings; it has been abundantly substantiated by the practice of English cultivators. We find on page 333 of the “British Husbandry,” an admirable work published under the superintendence of the Society for the Diffusion of Useful Knowledge, the following statement:

“The ashes of burnt straw have also been found beneficial by many intelligent practical farmers, from some of whose experiments we select the following instances. Advantage was taken of a fine day to fire the stubble of an oat-field soon after harvest, the precaution having been previously taken of sweeping round the boundary to prevent injury to the hedges. The operation was easily performed,

by simply applying a light to windward, and it completely destroyed every weed that grew, leaving the surface completely covered with ashes; and the following crop, which was wheat, produced full five quarters per acre. This excited further experiment, the result of which was, that in the following season, the stubble having been partly plowed in according to the common practice, and partly burned, and the land sown with wheat, the crop produced eight bushels per acre more on that portion which had been burned, than on that which had been plowed in. The same experiment was repeated, on different occasions, with similar results; and a following crop of oats having been laid down with seeds, the clover was found perfectly healthy, while that portion on which the burning of the stubble had been omitted, was choked with weeds. It must, however, be recollected, that if intended to have a decided effect, the stubble must be left of a considerable length, which will occasion a material deficiency of farmyard manure; though the advantages will be gained of saving the cost of moving the stubs, the seeds of weeds and insects will be considerably destroyed, and the land will be left unimpeded for the operation of the plow.

“On the wolds of Lincolnshire, the practice of not only burning the stubble, but even the straw of threshed grain, has been carried, in many cases, to the extent of four to six loads per acre; and, as it is described in the report of the county, has been attended, in all those instances, with very decidedly good effect. It is even said to have been found superior, in some comparative trials, to yard-dung, in the respective rate of five tons of straw to ten of manure!”

We frequently ride past immense piles of wheat straw, encumbering the yard or field where it was threshed; and never without thinking upon the unthriftiness of a farmer who ignorantly takes everything off his wheat land, returns nothing to it, and is content with annually diminishing crops.
