Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Hints on Soils and Fertilizers We have already learned that the soil con tains mainly two classes of materials, humus and mineral elements. We have defined humus as decayed vegetable matter, such as the re mains of plants that were not used by man, but left upon the soil. The elements of a mineral nature are just as essential to the welfare of the plant as the Organic matter, or humus. We will discuss these mineral ele ments from a chemical point of view in our next chapter, but we will now consider them briefly from a phy'sical standpoint.

Book excerpt: Excerpt from Soils and Fertilizers The attempt has been made so to present the subject that the pupil who has no knowledge of chemistry or other natural science will be able to understand it. No chemical symbols or formula: have been used. Use has been freely made of a limited number of names of chemical substances contained in commercial fertilizers which contribute to the nutrition of plants. These, however, are terms with which the pupil can familiarize himself as readily as with the geographical and other names that he has already mastered.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soils and Fertilizers, for Public Schools: A Discussion Upon the Nature and Treatment of Soils and the Value of Fertilizers There has been much ob eet'ion to the teaching of Agriculture in our District Schools, because teachers claim they do not have time to take up an additional subject, when they have so many subjects that are already required, and which must be taught. However, in recent years Agriculture has been coming into its own, and is being taught more and more in the schools. Teachers have begun to realize that any subject which holds the interest and attention of the pupils is worthwhile, and that any sub ect which does not hold their attention is not worthy of a place in our already crowded School course. In order to make Agriculture interesting to the pupil, we must base the work upon real practical problems which he can understand and appreciate. To do this is no small task, and it is a thing which demands a great deal of perseverance and initiative, on the part of teachers In such schools. The more ideas which an author attempts to incorporate into a text book, the more complex his text becomes, and the more difficult it is to follow. Therefore, in this text book we have taken' only a few of the most important conditions and have tried to incorporate them in such a manner that they can be used by the average district or graded school. We have tried further to make the book correct - theoretically and practically. The entire text has been written for boys and girls of the country schools, with these two things in mind, and the success which attends its use presupposes a proper presentation of many minor details, which it would be impossible to include under this cover. Many teachers get the idea that the sub ect of Agriculture as taught in our public schools is a Vocational Sub ect. This is' a mistaken idea, and the teachers should above all bear in mind that we are not making better farmers so much as we are making better men and women who are farmers. Naturally the teaching of Agriculture will make better farmers, and will serve to keep more of our boys on the farm.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soils, How to Handle and Improve Them Many of the early books on farming were written in a technical style. They smacked of the lecture room and the library rather than of the soil. They were scholarly rather than practical. A spirit of directness and simplicity is beginning to dominate agricultural literature. The modern type of farm books is born of actual contact with the soil and a desire to be of service to the men who are getting a living from the soil. They are democratic; they discuss common things in a plain way. The long and tedious tables of figures in the old books are giving place to crisp summaries. The technical lecture-room phrases are replaced by words in common use on farms. The idea is not to present less science - for nothing is so practical as sound science - but to present science in a simple and practical way. This new spirit is contemporaneous with the farmers' institute, the farmer's reading-course, Nature-study, elementary agriculture in the public schools and other efforts to serve the man who tills the soil. It is an expression of a general movement which aims to democracise agricultural teaching. This book is an attempt to set forth the important facts about the soil in a plain and untechnical manner. It is not a contribution to agricultural science, but an interpretation of it - a new presentation of what is already known.

This book was released on 2017-10-29 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Fertilizers in Relation to Soils and Crop Production Most young plants start from a seed, which contains an embryo, or germ, that is extremely rich in albuminoids, fat, phosphates, and potash. The seed also contains a store of food, in the form of starch, fat, etc, intended to nourish the young plant until the roots and leaves are sufficiently developed to gather their own supplies, The future health and vigor of the plant will depend on: (1) the amount of food available to the tiny rootlets sent out by the young plant: (2) the temperature of the soil, (3) an abundance of sunshine, and (4) a sufficient supply of oxygen. The plant requires oxygen for respiration, and it gives of carbon dioxide as a result of the oxidation of its food, that is, it breathes; it gives off water from its leaves, or lungs, it assimilates food, and it even excretes waste material. In all this it is very similar to the animal. But it even goes further, and collects its food from the simple substances, such as carbon dioxide. Ant. Various soluble salts found in the soil, and from these builds up the complex sugars, starches, fat, and albuminoids which are essential for the life processes of the plant and which are the only foods of the animal. It is subject to im provement by selection and breeding, as is the animal, but, unlike the animal, it is entirely dependent upon the supply of food constituents within its reach, and it has no way of drawing attention to its wants, excepting as its appearance may make them known to the careful and trained observer. A clear conception of the fact that an infant plant, like the infant animal, requires warmth, air. Sunshine, and an abundance of easily absorbed food, will greatly aid in under.

Book excerpt: Excerpt from Manures and Fertilizers: A d104-Book for College Students and a Work of Reference for All Interested in the Scientific Aspects of Modern Farming The preparation of this volume was undertaken for the purpose of meeting a distinct lack in collegiate agricultural textbooks in the United States. It was hoped to prepare a book reasonably free from extended details, such as are found in certain of the larger foreign works, and likewise to avoid the rather superficial treatment of the subjects which has necessarily characterized many of the books which have been written for the purpose of meeting the earlier requirements of the American agricultural colleges, and the present demands of agricultural high schools. The intent has been to provide in a measure for the needs of the graduate student in agriculture; also for the requirements of students in the agricultural colleges, teachers in agricultural schools, graduates of agricultural schools and colleges, agricultural institute lecturers, and the rapidly increasing number of intelligent men who are daily interesting themselves in the scientific phases of modern farming. In connection with the treatment of some of the newer and more controversial phases of certain of the topics, authorities have been cited freely, in order that the reader may readily pursue the subjects further, if desired. These citations have been introduced at the bottom of the respective pages, so as to permit of more convenient and ready reference than would be possible if they were placed at the ends of chapters, or at the end of the volume.

Download or read book Fertilizers and Their Use Classic Reprint written by Robert Harcourt and published by Forgotten Books. This book was released on 2018-03-17 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Fertilizers and Their Use On our comparatively new lands, and in general farm practice where a judicious rotation of crops is followed. And where grain is fed on the farm and the manure properly cared for, it may not be necessary to use commercial fertilizers; but where the nature of the crops grown prevents rotation, and where very little farmyard manure is produced, they may be required. More and more each year it is found that the increased cost of production and the consequent need of producing maximum crops, and the growing demands of the larger towns and cities for garden and fruit products of high quality, are causing market gardeners and fruit growers to consider seriously the advisability of using some form of fertilizer. This has created a demand for information concerning these substances which it has not been easy to fill; for experience has shown that the farmer must posses a wide knowledge of plants, soils and the fertilizers themselves before he can properly use them. To intelligently and economically use fertilizers, it is essential that the farmer understand the needs of the cr0ps, their power to gather the essential plant food constituents from the soil, and the purpose of their growth, i.e., whether the object is to produce an immature plant for early market, or whether maturity is required. He must also know something about the available supply of plant food' tn the soil and the nature of the fertilizer being used. These fertilizers are expensive, and unless they are intelligently applied in conjunction with very thorough cultivation they will not give their best results. They cannot take the place of cultivation; for they are food materials, and can only aid the growth of the plant as they are absorbed by the roots, and these cannot develop fully in a poorly cultivated soil.
