Leaves from the woods, buckwheat straw, bean, pea, and hop vines, etc., plowed under long enough before planting to allow them time to rot, are very beneficial. Sea-weed, when bountifully applied, and turned under early in the fall, has no superior as a manure for the potato. No stable or barn-yard manure should be applied to this crop. If such nitrogenous manure must be used on the soil, it is better to apply it to some other crop, to be followed the succeeding year by potatoes. The use of stable manure predisposes the tubers to rot; detracts very much from the desired flavor; besides, generally not more than one half as many bushels can be grown per acre as can be obtained by using manures of a different nature. Market gardeners, many of whom from necessity plant on the same ground year after year, often use fine old stable manure with profit. Usually they plant only the earlier varieties, crowd them with all possible speed, dig early, and sell large and little before they have time to rot, thus clearing the ground for later-growing vegetables. Thus grown, potatoes are of inferior quality, and the yield is not always satisfactory. Flavor, however, is seldom thought of by the hungry denizens of our cities, in their eagerness to get a taste of something fresh. Market gardeners will find great benefit from the use of wood-ashes, lime, and the phosphates. Sprinkle superphosphate in the hill at the rate of two hundred pounds per acre; mix it slightly in the soil with an iron rake or potato-hook, then plant the seed. Just before the last hoeing, sprinkle on and around the hill a large handful of wood-ashes, or an equal quantity of lime slacked in brine as strong as salt will make it. But for the generality of farmers, those who grow only their own supply, or those who produce largely for market, no other method of preparing the soil is so good, so easy, and so cheap as the following; it requires time, but pays a big interest: Seed down the ground to clover with wheat or oats. As soon as the grain is off, sow one hundred and fifty pounds of plaster (gypsum) per acre, and keep off all stock. The next spring, when the clover has made a growth of two inches, sow the same quantity of plaster again. About the tenth of July, harrow down the clover, driving the same direction and on the same sized lands you wish to plow; then plow the clover neatly under about seven inches deep. Harrow down the same way it was plowed, and immediately sow and harrow in two bushels of buckwheat per acre. When it has grown two inches, sow plaster as before; and when the buckwheat has grown as large as it will, harrow down and plow under about five inches deep. This, when cross-plowed in the spring sufficiently deep to bring up the clover-sod, is potato ground _first-class in all respects_.
