From this, we see that we may pursue either one of two courses. After we know the exact composition of the soil—which we can learn only from correct analysis—we may manure it with a view either to making it fertile for all kinds of plants or only for one particular plant. For instance, we may find that a soil contains a very little phosphoric acid, and no potash. If we wish to raise potatoes on such a soil, we have only to apply potash (if the soil is good in other particulars), which is largely required by this plant, though it needs but little phosphoric acid; while, if we wish to make it fertile for wheat, and all other plants, we must apply more phosphoric acid as well as potash. As a universal rule, it may be stated that to render a soil fertile for any particular plant, we must supply it (unless it already contains them) with those matters which are necessary to make the ash of that plant; and, if we would render it capable of producing all kinds of plants, it must be furnished with the materials required in the formation of all kinds of vegetable ashes.

It is not absolutely necessary to have the soil analyzed before it can be cultivated with success, but it is the cheapest way.

How is the fertility of the soil to be maintained, if the crops are sold?

What rule is given for general treatment?

Give an instance of matters in the soil that are to be rendered available by mineral manures?
