TAILIEUCHUNG - CHARACTER AND VARIETIES OF MANURES NAND EXCREMENTS OF ANIMALS

To understand the science of manures is the most important branch of practical farming. No baker would be called a good practical baker who kept his flour exposed to the sun and rain.

May mechanical effects be produced by chemical action How does potash affect the soil To understand the science of manures is the most important branch of practical farming. No baker would be called a good practical baker who kept his flour exposed to the sun and rain. No shoemaker would be called a good practical shoemaker who used morocco for the soles of his shoes and heavy leather for the uppers. No carpenter would be called a good practical carpenter who tried to build a house without nails or other fastenings. So with the farmer. He cannot be called a good practical farmer if he keeps the materials from which he is to make plants in such a condition that they will have their value Pg 94 destroyed uses them in the wrong places or tries to put them together without having every thing present that is necessary.

In this section of our work we mean to convey some of the information necessary to this branch of practical farming. We shall adopt a classification of the subject somewhat different from that found in most works on manures but the facts are the same. The action of manures is eithermechanical or chemical or a combination of both. For instance some kinds of manure improve the mechanical character of the soil such as those which loosen stiff clay soils or others which render light sandy soils compact these are calledmechanical manures. Some again furnish food for plants these are called chemicalmanures. Many mechanical manures produce .
