Página 305 - ... 9. There is strong presumptive evidence that the nitrogen which exists in the air, in the shape of ammonia and nitric acid, and descends, in these combinations, with the rain which falls on the ground, satisfies, under ordinary circumstances, the requirements of the clover crop.
Página 303 - ... the better it is, nevertheless, made thereby for producing in the succeeding year an abundant crop of wheat, other circumstances being favorable to its growth. " Indeed no kind of manure can be compared, in point of efficacy for wheat, to the manuring which the land gets in a really good crop of clover. The farmer who wishes to derive the full benefit from his clover-lay, should...
Página 284 - ... large quantities of manure were used. Taking all these circumstances into account, is there not presumptive evidence that notwithstanding the removal of a large amount of nitrogen in the clover-hay, an abundant store of available nitrogen is left in the soil, and also that in its relations towards nitrogen in the soil clover differs essentially from wheat?
Página 136 - ... beans then), than to make the ready dollar. In this I have fully succeeded. I wanted to make two spears of grass grow where but one grew before, and I am sure I am getting three, some of my neighbors say four ; however, I call it three. The meadows that used to cut from one-half to one ton of hay per acre, now yield on an average over two.
Página 303 - When the clover-lay is plowed up early, the decay of the clover is sufficiently advanced by the time the young wheat-plant stands in need of readily available nitrogenous food, and this, being uniformly distributed through the whole of the cultivated soil, is ready to benefit every single plant. This equal and abundant distribution of food, peculiarly valuable to cereals, is a great advantage, and speaks strongly in favor of clover as a preparatory crop for wheat. " Nitrate of soda, an excellent...

The society shall consist of such citizens of the state as shall signify in writing their wish to become members and shall pay, on subscribing, not less than one dollar and annually thereafter one dollar; and also of honorary and corresponding members.

The soils were pounded down and passed through a wire sieve. "The three layers of soil, dried and reduced to powder, were mixed together, and a prepared average sample, when submitted to analysis, yielded the following results : — Composition of...

Agricultural experiences contradicting prevailing, and it may be, generally current theories, are, unless I am much mistaken, of far more common occurrence than may be known to those who are either naturally unobservant or unacquainted with many of the details of farming operations. Indeed, an interesting and instructive treatise might be written on the apparent anomalies in agriculture, and a collection of trustworthy facts of the kind alluded to would afford valuable...
Página 284 - In chemical inquiries especially, nothing must be taken for granted that has not been proved by direct experiment. The following questions naturally suggest themselves in reference to this subject : What is the amount of nitrogen in soils of different characters ? What is the amount, more particularly after a good and after an indifferent crop of clover ? Why is the amount of nitrogen in soils larger after clover than after wheat and other crops ? Is the nitrogen present in a condition in which it...
Página 276 - ... soil-constituents by the crops usually sold off the farm, leading, as is well known, to more or less rapid deterioration and gradual exhaustion of the land. Even the best wheat-soils of this and other countries become more and more impoverished, and sustain a loss of wheat-yielding power, when corn-crops are grown in too rapid succession without manure. Hence the universal practice of manuring, and that also of consuming oil-cake, corn, and similar purchased food on land naturally poor, or partially...
