The third is also a mineral element, which completes the trine in fertility. Such crops as the cereals draw mostly on the phosphates within the soil; but a crop of potatoes draws mostly on the potash contained in the soil. You cannot go on indefinitely raising potatoes on the same land without furnishing potash. If you do, the tubers produced will be entirely lacking in starchy matter and altogether too much gluten. When these three constituent elements of fertility are in the land and rightly balanced, then your land is in the highest condition of fertility. But if one of these elements is taken out by poor methods of farming, then your land, to use a horseman’s phrase, is said to be out of fettle. But in the next twenty-five years, when the farmers of this country get down to hardpan, when the yield of their crops has deteriorated to such a degree not only in the quantity of the product, but also in the quality of the product, which is more important than quantity, in other words, when necessity compels them, then I look for the fruits of the labors of the agricultural experiment colleges. Renewing the soil is analogous to the redemption of the soul of man. We have the Word for it, and the promises are sure and steadfast; yet we may have all the knowledge on the subject, but that will not obtain eternal life. The Lord cannot save us unless we co-operate with him and do our part. While I am, and always have been, an earnest advocate of the greater use of legumes in restoring the fertility of our land, I am fully alive to the importance of putting back all the manure from the farmyard onto the land. I was raised on an extensive truck garden, and there is no reason to doubt the capacity of the soil to yield a product to which no one can yet forecast the limit. As an instance of the possibilities of the land under intensive culture, the Long Island market gardeners apply from seventy to eighty tons of stable manure to their early cabbages per acre, and as the plants are much closer and are much more sure to head universally, a yield of fifty tons to the acre is not an excessive estimate. The above will show what can be done with a liberal supply of stable manure.
