Although good crops may follow the application of lime, the latter is not a direct fertilizer or manure and is no substitute for such.
The pitchers accumulate vast quantities of insects in the course of a season, and must thus abundantly manure the surrounding soil when they die.
The phosphate thus produced forms an efficacious turnip manure, and is quite equal in value to that produced from any other source.
The most suitable soil is a light, sandy loam enriched with well decomposed manure, in a rather moist situation.
Its industrial establishments include factories for tobacco, cloth, matches, leather, artificial manure, besides breweries and distilleries.
The acid renders it available as a manure by converting the calcium phosphate, Ca 3 P 2 O 8, that it contains into the soluble monocalcium salt, CaH 4 P 2 O 8, or "superphosphate."
The fact that the growth of a leguminous crop, such as red clover, leaves the soil in a higher condition for the subsequent growth of a grain crop - that, indeed, the growth of such a leguminous crop is to a great extent equivalent to the application of a nitrogenous manure for the cereal crop - was in effect known ages ago.
Most of the nitrogen in the straw of the cereals, and a very large proportion of that of the much more highly nitrogenyielding crops, returns to the land as manure, for the benefit of future cereals and other crops.
But a long course of continuous cropping with these grain crops, without affording compensation to the soil in the form of manure or deep cultivation, has so ex.
Manure, &c., and a covered shed for loading and unloading packages and materials which it is undesirable to expose to the weather.
Other industries are the manufacture of cellulose, artificial manure, flour and malt; and there are saw-mills, iron foundries and breweries in the town.
The chief industries of Grimsby are shipbuilding, brewing, tanning, manufactures of ship tackle, ropes, ice for preserving fish, turnery, flour, linseed cake, artificial manure; and there are saw mills, bone and corn mills, and creosote works.
The discovery of the uses of the bare fallow and of manure, by making it possible to raise crops from the same area for an indefinite period, marks a stage of progress.
Repetition of one crop in the field exhausts the ground; but rotation of the crops is good for the soil.
Much stress is laid on the value of manure, and mention is made of clover.
It is in itself an excellent manure, Sir Richard adds; and so it should be, to enable land to bear this treatment.
He was one of the first to use oil-cake and bone-manure, to distinguish the feeding values of grasses, to appreciate to the full the beneficial effects of stock on light lands and to realize the value of long leases as an incentive to good farming.
In one case, indeed, the average produce by mixed minerals and nitrogenous manure was more than that by the annual application of farmyard manure; and in seven out of the ten cases in which such mixtures were used the average yield per acre was from over two to over eight bushels more than the average yield of the United Kingdom (assuming this to be about twenty-eight bushels of 60 lb per bushel) under ordinary rotation.
The average results show that, under all conditions of manuring - excepting with farmyard manure - the produce was less over the later than over the earlier periods of the experiments, an effect partly due to the seasons.
The exhaustion of the soil induced by both barley and wheat is, however, characteristically that of available nitrogen; and when, under the ordinary conditions of manuring and cropping, artificial manure is still required, nitrogenous manures are, as a rule, necessary for both crops, and, for the spring-sown barley, superphosphate also.
Both the quantity and the quality of the produce, and consequently its feeding value, must depend greatly upon the selection of the best description of roots to be grown, and on the character and the amount of the manures, and especially on the amount of nitrogenous manure employed.
Other essential conditions of success will commonly include the liberal application of potash and phosphatic manures, and sometimes chalking or liming for the leguminous crop. As to how long the leguminous crop should occupy the land, the extent to which it should be consumed on the land, or the manure from its consumption be returned, and under what conditions the whole or part of it should be ploughed in - these are points which must be decided as they arise in practice.
The outgoing tenant must leave the straw and manure of the year, if he received them at the beginning of his lease, and even where he has not so received them, the owner may retain them according to valuation (Art.
The bed forms a warm seed-bed in the cool weather of early spring, and holds the manure which is drilled in usually to better advantage.
Although used in the early days to a limited extent as a food for milch cows and other stock, and to a larger extent as a manure, no systematic efforts were made anywhere in the South to manufacture the seed until the later 'fifties, when the first cotton seed mills were established.
Industries include slate quarrying, shipbuilding, iron and brass foundries, alum, vitriol, manure, guano and tobacco works.
The chief industrial establishments are iron foundries, railway and motor engineering works, breweries, flour-mills, tanneries and manufactories of confectionery, artificial manure, &c. There is water communication by the Ouse with the Humber, and by the Foss Navigation to the N.E.
Nitric acid (up to 50%) is formed in the first tower, and weaker acids in the successive ones; the last tower contains milk of lime which combines with the gases to form calcium nitrite and nitrate (this product, being unsuitable as a manure, is decomposed with the acid, and the evolved gases sent back).
The trees are to be top-dressed from time to time with well-decayed manure and turfy loam, and considerable space must be left in the pots for this and the watering.
It is well after the borders are completed to remove the top soil, in which no roots are to be found, every two or three years, and to replace it with a mixture of good loam, rotten manure, lime rubbish and bone meal, to the depth of 6 or 7 in.
The shoots are trained up near the glass, and, with plenty of heat (top and bottom) and of water, with air and light, and manure water occasionally, will form firm, strong, well-ripened canes in the course of the season.
The Indians and white settlers used it as a manure, and the name is Narragansett for "fertilizer."
It is an important industrial centre, carrying on cotton weaving and spinning, tanning, distilling, and the manufacture of coffee, sugar, manure and saltpetre.
The plant grows freely in good garden soil, preferring a deep welldrained loam, and is all the better for a top-dressing of manure as it approaches the flowering stage.
Farm-yard manure, guanos and other fertilizers.
In the case of plants the method of procedure was to grow some of the most important crops of rotation, each separately year after year, for many years in succession on the same land, (a) without manure, (b) with farmyard manure and (c) with a great variety of chemical manures; the same description of manure being, as a rule, applied year after year on the same plot.
Experiments on an actual course of rotation, without manure, and with different manures, have also been made.
Amongst the field experiments there is, perhaps, not one of more universal interest than that in which wheat was grown for fifty-seven years in succession, (a) without manure, (b) with farmyard manure and (c) with various artificial manures.
Even without manure the average produce over forty-six years, 1852-1897, was nearly thirteen bushels per acre, or about the average yield per acre of 1 The higher yield of wheat in the later years of the 19th century appears to be largely attributable to better grain-growing seasons.
Experiments upon the growth of barley for fifty years in succession on rather heavy ordinary arable soil resulted in showing that the produce by mineral manures alone is larger than that without manure; that nitrogenous manures alone give more produce than mineral manures alone; and that mixtures of mineral and nitrogenous manure give much more than either used alone - generally twice, or more than twice, as much as mineral manures alone.
Of the twenty plots into which this land is divided, two were left without manure from the outset, two received ordinary farmyard manure for a series of years, whilst the remainder each received a different description of artificial or chemical manure, the same being, except in special cases, applied year after year on the same plot.
