Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soils and Fertilizers It is evident from the preceding example that any thing like an adequate idea of the growth and compo sitiou of plant bodies could not be gained until the composition of air and water was established. The discovery of oxygen by Priestley in 1774, of the composition of water by Cavendish in 1781, and of the r61e which carbon dioxide plays in plant and animal life by De Saussure and others in 1800, formed the nucleus of our present knowledge regarding the sources of matter stored up in plants. It was between 1760 and 1800 that alchemy lost its grip because of advances in knowledge and the way was opened for the development of modern chemistry.

Book excerpt: Excerpt from Commercial Fertilizers and Soil Fertility in California When any one of the elements, nitrogen, phosphorus, or potassium, is so lacking that growth of plants is much restricted, it is spoken of as the limiting factor if there is. An adequate supply of the other two. In case the supply of either of the two is low, one of them may become the limiting factor in plant growth, after the supply of the previously deficient element is made adequate. The important. Point is to produce a favorable condition in the soil for the growth of plants by adding that element in which the soil. Is deficient. In the majority of cases, California. Soils are most likely to be deficient in nitrogen. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.

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 Fertilizers What then is the first duty of the agriculturist in Porto Rico indeed, what is the prime necessity? It is to bring back to the land some' of the old-time fertility which gave to the island the name Porto Rico - 4rich port. The elements of plant food most likely to be needed in soils are nitrogen, phosphorus, and potash. Very poor soils, like most of those found in' Porto Rico, need all three of these, and in many instances lime also. 'therefore, in improving the soil we must seek out and apply especially all the nitrogen, phosphorus, and potash that we can find. Upon the application of these to our fields depends the future prosperity of the island. Let us then look to the sources from which we can obtain these elements. Of fertility.

Download or read book The Relation of Fertilisers to Soil Fertility Classic Reprint written by Frederick Bickell Guthrie and published by . This book was released on 2015-07-07 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Relation of Fertilisers to Soil Fertility Recent investigations have brought to light a host of other causes of infertility, but the idea still persists at the back of many soil analyses, that the determination of the amount of certain specified plant-foods, dissolved by specific solvents from the soil, is a certain guide to the nature of the manuring required. As a matter of fact, neither the chemical composition of the soil nor of the crop affords any certain foundation on which advice as to manuring can be based. A. D. Hall and E. J. Russell, dealing with the results of a soil survey of the south-eastern counties of England, draw, amongst other general conclusions, the following which have special reference to the connection between the composition of the soil and plant: "We are not as yet in a position to deduce the agricultural properties of a soil, either its behaviour under cultivation or its adaptability to particular crops, except in the roughest general fashion." In dealing with a number of typical wheat-soils the authors say, "chemical analysis of these soils revealed no connection between their chemical composition and their suitability for wheats," and the same remark applies no doubt to other crops. They also point out that excess or deficiency of any particular plant-food, such as nitrogen, does not necessarily imply a fertile or infertile soil. Even in the case of calcium carbonate, they show that many soils poorly supplied with this ingredient are not benefited by the application of lime, whereas for other soils examined, containing the same or a greater proportion, liming is essential. They find that, "other things being equal, dry soils are more likely to respond to potassic manuring than others better supplied with water, but no richer in available potash." The same applies to phosphoric acid. "Little, if any, direct connection can be traced between the phosphoric acid and the productiveness." As far as regards the value of soil-analysis, as a basis on which to afford advice as to soil treatment, I have no reason to alter the opinion expressed in a paper on "Soil Analysis," read before this Association at the Brisbane meeting, 1895, wherein the view is expressed that a rational scheme of soil-analysis which shall attempt rather to determine the factors influencing fertility than to elaborate methods for determining the chemical constitution of the soil, can be made of considerable value to the farmer. This statement has been amply borne out by experience, and to day the analysis of farmers soils on the lines then laid down is one of the functions of the Department most regularly availed of by farmers. In spite of all the labour expended for many years on this subject, manuring still remains very largely empirical in its nature. We know, in a broad and general way, that a soil deficient in plant-food is not likely to produce good crops without manuring, and that a soil rich in plant-food is likely to prove a fertile one. But much further than this we cannot go. If a soil is well supplied with, say nitrogen and potash, but poor in phosphates, it by no means follows with any certainty that it will be benefited by phosphatic manuring.
