Clover, instead of taking nutriment from the atmosphere for the wheat or corn plant, gathers its essential elements from the soil in which its roots have penetrated, and which too, by their powerful growth, can push themselves where the wheat root can not until a way is opened for it. The clover plant, when cut for hay, will remove from the acre from two hundred and fifty to three hundred and fifty pounds of inorganic matter; while the wheat plant removes, in its straw, about two hundred pounds, and in its seed from, twenty-five to thirty pounds. The largest amount of removed matter in the straw is silica, which exists in the clover plant only in minute quantities. Clover is, however, rich in the alkalies and phosphates; and hence it follows that a single clover crop will supply a large amount of the valuable and expensive nutriments to two or more crops of the cereals or grains, even from its decayed roots. This modified view of the value and use of clover in a rotation seems to me agreeable to observation, and to all the phenomena of growth and nutrition. In weak lands or soils the clover tops should not be removed, while in strong soils it is not of so much consequence to plough in the crop; indeed when the growth is large, and can not be broken up and incorporated with the soil, it has seemed to exert an injurious effect.
