Book Synopsis First Principles of Soil Fertility (Classic Reprint) by : Alfred Vivian
Download or read book First Principles of Soil Fertility (Classic Reprint) written by Alfred Vivian and published by Forgotten Books. This book was released on 2018-02-07 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from First Principles of Soil Fertility This little book is intended primarily for home read ing. It is written, however, largely from lecture notes used by the author in a course in soil fertility given to winter course students, and, therefore, will be found to be a suitable text for short courses. It is an at tempt to present in non-technical language a subject of great scientific and practical interest to the farmer. The subject of Soil Fertility is so large, that each phase of it could of necessity be only briefly considered in a small book, and the writer did not pretend to make the discussion of any topic exhaustive. For this reason some things have been omitted which might have been discussed with profit in a larger work. Only the more important facts concerning the maintenance of fertility have been presented, but it is believed that the statements so far as they go are in accord with the best scientific thought and practice of the day.

Book Synopsis The Relation of Fertilisers to Soil Fertility (Classic Reprint) by : Frederick Bickell Guthrie

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.

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.

Download or read book Soil Fertility (Classic Reprint) written by W. C. Welborn and published by Forgotten Books. This book was released on 2017-10-29 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soil Fertility All plants are made up of substances taken from the earth and the air. The roots of plants absorb water from the moist soil, and with it some of the solid parts of the earth dissolved in the water. When a plant is burned, the ash remaining is composed mainly of what came from the earth during the growth of the plant. Plants, after becoming dry, have generally from 1 to 10 per cent of ash. The other 90. To 99 parts were derived from the air. Practically half the weight of dry plants is derived directly from the air through the medium of the leaves. All plant leaves absorb carbonic-acid gas - the gas that is used to charge mineral waters. This gas is easily produced by pouring strong acid on limestone. It is produced in nature on a vast scale by the burning and rotting of wood and other vegetable substances. It is also given off from the lungs of animals. When the leaves of plants absorb carbonic-acid gas from the air, the plants use the carbon (convert ing it into solid tissue), and give off oxygen gas, pure as originally. Oxygen for breathing is necessary to the life of man and animals. It is thus seen that animals and plants are dependent upon each other for the breath of life. This mutual dependence does not stop here. Animals must have certain salts which help to make up the solid parts of the earth, in order to live and grow. But man and animals can not digest stone or earth. These earthy salts must be taken into plants and be combined there into substances digestible and nourishing to animals. Then, the manure of animals is a good food for plants. When animals die their bodies also add fertility to the earth. That a farmer can not enrich the air with plant food so as to benefit his cr0ps is readily seen. This has been done successfully only in green houses, where the air can be controlled. All efforts in this direction must be mainly confined to adding plant food to the soil, or to improv ing the condition of the soil so that its own large stores of plant food may be more easily taken up by plants.
