Right Use of Lime in Soil Improvement The cultivation of our whole country has been such, as to take away the phosphoric acid from the soil without returning it, except in very minute quantities. The Elements of Agriculture A Book for Young Farmers, with Questions Prepared for the Use of Schools We observe then, that the peat contains in a given quantity, about one-third more organic matter, an equal amount of lime and nitrogen; but is deficient in potash, magnesia, phosphoric and sulphuric acids. Peat and its Uses as Fertilizer and Fuel That is to say, that the phosphoric acid in the sludge did not exert more than one-fifth of its theoretical effect. Manures and the principles of manuring At a certain stage of this descent, a blow seemed to strike her—phosphoric radiance sprang forth from her eye-balls; and immediately a mighty theatre expanded within her brain. Blackwood's Edinburgh Magazine, Volume 57, No. 357, June, 1845 Beyond, the surface was sparkling with phosphoric points, as if the sky, now covered with a uniform drapery of dark clouds, had dropped its starry mantle upon the sea. The Tiger Hunter How have the Genesee and Mohawk valleys been affected by this removal of phosphoric acid?

The Desert Home The Adventures of a Lost Family in the Wilderness The source mentioned, from which to obtain phosphoric acid, is the bones of animals. The Elements of Agriculture A Book for Young Farmers, with Questions Prepared for the Use of Schools The soil is naturally rich in potash, nitrogen, and lime, but requires superphosphate, as the percentage of phosphoric acid is low. Wheat Growing in Australia Some of these substances contain much nitrogen or phosphoric acid, but in their natural condition ferment when applied to the soil at a slow rate. Manures and the principles of manuring The manufacture of superphosphates depends on the existence of two different compounds of phosphoric acid and lime, one of which contains three times as much lime as the other.

Crops and Methods for Soil Improvement The fire-flies were abroad in thousands; and their phosphoric lamps, more than usually luminous, also betokened the approach of a rain-storm. The Boy Hunters There were the commoner corrosives—nitric, hydrochloric, phosphoric, and sulphuric acid. The Status Civilization It will further be noticed that the amounts of phosphoric acid removed by the different crops differ very much less than those of nitrogen and potash. Manures and the principles of manuring Very little is known in regard to the need of phosphates or phosphoric acid.... Human Foods and Their Nutritive Value The home-mixer may substitute tankage of guaranteed analysis for part of the nitrogen and phosphoric acid. Crops and Methods for Soil Improvement On this account molybdic acid is often used in the estimation of the phosphoric acid present in a substance. An Elementary Study of Chemistry Some of the phosphoric acid and considerable amounts of the potash are also found in the liquid manure. Agriculture for Beginners Revised Edition This is obtained by dividing the market value of a manure per ton by the percentage of nitrogen, phosphoric acid, and potash it contains. Manures and the principles of manuring How do you test a baking powder for phosphoric acid?

An Elementary Study of Chemistry The three most valuable things in commercial fertilizers are nitrogen, potash, and phosphoric acid. Agriculture for Beginners Revised Edition A point of considerable importance to notice is, that a soil rich in lime can stand a larger application of phosphoric acid than one poor in lime. Manures and the principles of manuring Elements of Fertility.—Three elements are necessary for the growth of apple trees, nitrogen, phosphoric acid, and potash. Apple Growing If a fertilizer containing 3 per cent of nitrogen, 10 per cent of phosphoric acid, and 6 per cent of potash serves the wheat well, it will serve the timothy that starts in the wheat. Crops and Methods for Soil Improvement With phosphoric acid magnesium forms salts similar to those of calcium. An Elementary Study of Chemistry This treatment changes the phosphoric acid into a form ready for plant use. Agriculture for Beginners Revised Edition It is some considerable time since we have recognised that the only three ingredients it is, as a rule, expedient to apply as artificial manures, are nitrogen, phosphoric acid, and potash. Manures and the principles of manuring The effect of phosphoric acid and potash on the tree and fruit is much more uncertain. Apple Growing If the soil is sandy and deficient in potash, the percentage of phosphoric acid may be cut to 8, and the percentage of potash raised to 10, and all these crops will profit thereby. Crops and Methods for Soil Improvement Could phosphoric acid be substituted for sulphuric acid in the preparation of the common acids? An Elementary Study of Chemistry The ordinary cotton fertilizer consists principally of nitrogen, of potash, and of phosphoric acid. Agriculture for Beginners Revised Edition With regard to the nitrogen and phosphoric acid, we may ask if these two constituents are in the best proportions. Manures and the principles of manuring Such an application will not only go far toward supplying the necessary nitrogen, phosphoric acid, and potash, but especially if coarse will add considerable humus and improve the physical condition of the soil. Apple Growing A richer soil may want the phosphoric acid and potash without the nitrogen. Crops and Methods for Soil Improvement On cooling from the fused state it forms a glassy solid, and on this account is often called glacial phosphoric acid. An Elementary Study of Chemistry The sweet potato draws potash, nitrogen, and phosphoric acid from the soil, but in applying these as fertilizers the grower must study and know his own soil.

An Elementary Study of Chemistry On page 24 you learned that phosphoric acid, potash, and nitrogen are the foods most needed by plants. Agriculture for Beginners Revised Edition As their value depends on their nitrogen and phosphoric acid, these alone have been given. Manures and the principles of manuring You will readily perceive, therefore, that the sulphuric and phosphoric acids require amendments, and the ammonia should be changed from a carbonate to a sulphate of ammonia, which is not volatile. Guano A Treatise of Practical Information for Farmers This gives nearly the same quantity each of nitrogen, phosphoric acid, and potash, and is near a 7-7-7 fertilizer. Crops and Methods for Soil Improvement For this reason commercial hydrogen dioxide always contains phosphoric acid. An Elementary Study of Chemistry Lime is just as necessary to plant growth as the potash and nitrogen and phosphoric acid about which we hear so much, but it cannot take the place of these plant foods. Agriculture for Beginners Revised Edition In one important respect do the drainings of manure-heaps differ from urine—that is, in the percentage of phosphates they contain, the latter being practically devoid of phosphoric acid. Manures and the principles of manuring Potassic fertilizers give the best results when applied to clovers, but dressings of phosphoric acid may also be helpful. Clovers and How to Grow Them If there had been no applications of phosphoric acid and potash, the clover would have failed to maintain fertility, as is proved by other plats in this experiment. Crops and Methods for Soil Improvement For example, a solution of hydrogen dioxide decomposes more slowly when it contains a little phosphoric acid than when perfectly pure. An Elementary Study of Chemistry The elements usually lacking in wheat soils are nitrogen, phosphoric acid, and potash. Agriculture for Beginners Revised Edition A very considerable variation in the amount of phosphoric acid occurs for the reason above stated, the guano made from fish-scrap being naturally much richer in this ingredient than whole-fish guano. Manures and the principles of manuring In time the supply of phosphoric acid and potash might run low, but not for a long term of years. Clovers and How to Grow Them In the same way the land-owner may forget the necessity of any kind of plant-food in the soil except nitrogen, phosphoric acid, potash, and lime.

Fables of Infidelity and Facts of Faith Being an Examination of the Evidences of Infidelity Two of these plant foods, namely, phosphoric acid and potash, are minerals. Agriculture for Beginners Revised Edition It is a valuable manure, especially so for its nitrogen, which varies from 4 to 8 per cent, while it contains of phosphoric acid from 13 to 20 per cent. Manures and the principles of manuring But lest it should, attention should be given to fertilizing the land occasionally with farmyard manure, or with phosphoric acid and potash applied as commercial fertilizers. Clovers and How to Grow Them Thirty pounds of acid phosphate to each 100 pounds of the manure gives a mixture containing one pound of nitrogen, three pounds of phosphoric acid, and two fifths of a pound of potash. Crops and Methods for Soil Improvement In other words, the use of superphosphate furnishing only, or principally, phosphoric acid, lime and sulphuric acid, must have a tendency to impoverish the soil of nitrogen and potash.

Crops and Methods for Soil Improvement This with phosphoric acid makes phosphate of lime, the basis of the bones and teeth, in which nearly all the calcium of the body is found. Public School Domestic Science The principles of the method are as follows:—If the substance does not already contain sufficient phosphoric oxide to saturate the alumina, some phosphate is added. A Text-book of Assaying: For the Use of Those Connected with Mines. In this way the increase in returns could only be due to the phosphoric acid. Manures and the principles of manuring Those three are potash, which is abundant and will be abundant 100 years from now, phosphoric acid, or phosphorus, with which our soils are fairly well supplied, and nitrogen, which comes from the vegetable matter.

The House by the Church-Yard The crystals are sometimes used as a standard for phosphoric acid. A Text-book of Assaying: For the Use of Those Connected with Mines. But as this could also be produced by an overdose of soluble phosphoric acid as well as ammonia salts, it is not a property that belongs exclusively to nitrate of soda. Manures and the principles of manuring Each lemon yields two to eight drams of acidulous juice and contains seven to nine per cent of citric acid, besides phosphoric and malic acids, in combination with potassa and other bases. Mother's Remedies Over One Thousand Tried and Tested Remedies from Mothers of the United States and Canada The supply of phosphoric acid from bone is too small, when compared with the land's need, to deserve more than a small fraction of the consideration it receives by users of commercial fertilizers.

Manures and the principles of manuring In other words, he must give it more nitrogen, phosphoric acid, and potash than it can use for simple growth and maintenance, and thus make it burst forth into flower-or fruit-product. The Fat of the Land The Story of an American Farm It varies greatly in content of phosphoric acid. Crops and Methods for Soil Improvement We learned in a previous chapter that the plant foods, nitrogen, phosphoric acid, potash and lime, are apt to be found wanting in sufficient available quantities to supply the needs of profitable crops. The First Book of Farming Instead of separating and weighing this compound, the phosphoric oxide in it can be determined by titration. A Text-book of Assaying: For the Use of Those Connected with Mines. As has been shown in the Introduction, there is practically in the case of most soils no necessity to add to a manure any more than the three ingredients, nitrogen, phosphoric acid, and potash. Manures and the principles of manuring Less nitrogen and more phosphoric acid and potash are to be used, and the mulch should not be removed in the early spring. The Fat of the Land The Story of an American Farm The value of a pound of phosphoric acid in floats, as compared with that of a pound in the treated rock, known as acid phosphate, is a matter upon which scientists differ widely.

The First Book of Farming It should be borne in mind that these oxides will also contain any phosphoric oxide that happened to be in the mineral. A Text-book of Assaying: For the Use of Those Connected with Mines. This is due to the fact that the most of their potash, phosphoric acid, and nitrogen pass into the body of the trees at the approach of winter. Manures and the principles of manuring The green leaves constitute the machinery of the manufacture, for which the solar light from above, and the potash, phosphate of lime, phosphate of magnesia, and phosphoric acid from below are the raw materials.

Blood absorbs oxygene from the air, whence phosphoric acid changes its colour, gives out heat, and some phlogistic material, and acquires an ethereal spirit, which is dissipated in fibrous motion. Zoonomia, Vol. I Or, the Laws of Organic Life The use of fifty pounds of acid phosphate to each ton of manure will assist materially in preserving the nitrogen, and the gain in phosphoric acid will repay all the cost. Crops and Methods for Soil Improvement This form still continues to take on lime and by and by gets back to the original insoluble form called insoluble phosphoric acid. The First Book of Farming It is better, however, to carry the separation so far as to get phosphoric acid, an alkaline phosphate, or the magnesia precipitate. A Text-book of Assaying: For the Use of Those Connected with Mines. The older, therefore, a rock is, the richer it is likely to be in phosphoric acid.

A soil that is deficient in the three may not give any return from potash alone, and usually does not, although it may give a marked increase from use of phosphoric acid alone. Crops and Methods for Soil Improvement Heavy soils are generally supplied with potash but lack phosphoric acid. The First Book of Farming On the other hand, very secondary results were obtained with phosphoric and sulphuric acids. Scientific American Supplement, No. 832, December 12, 1891 As an example of how, in many cases, the amount of phosphoric acid removed from the farm is very often much greater than that restored, a case quoted by Crusius may be cited. Manures and the principles of manuring Seeds that have a thick cuticle or bran, and little gluten, contain a smaller per centage of phosphoric acid, and more silica.

Nearly all the phosphoric acid has come from rock, and its use has been necessary and profitable, but the misrepresentation fostered the old-time prejudice. Crops and Methods for Soil Improvement We also learned that of the plant foods there is often not enough available nitrogen, phosphoric acid, potash and lime for the needs of the growing plants. The First Book of Farming The difficulty from excess of lime is overcome by adding it now and then during carbonatation; but other means are found desirable; and phosphoric acid, magnesia, soda, etc., have been used with success. Scientific American Supplement, No. 832, December 12, 1891 The risks of loss of phosphoric acid in the treatment of farmyard manure are not so great as in the case of nitrogen.
