Seite v - A sower went out to sow his seed ; and as he sowed, some fell by the way-side, and it was trodden down, and the fowls of the air devoured it ; and some fell upon a rock, and as soon as it was sprung up, it withered away, because it lacked moisture ; and some fell among thorns, and the thorns sprang up with it, and choked it ; and other fell on good ground, and sprang up, and bare fruit an hundred fold. And when He had said these things, He cried, He that hath ears to hear, let him hear.
Seite iii - Where grows ? — where grows it not? If vain our toil, We ought to blame the culture, not the soil...
Seite 192 - ... years ago it was recognised by the Romans that the occasional growth of plants of the leguminous family had the effect of increasing the growth of the gramineous crops with which they were alternated, and it was stated that the effect was equivalent to that of applying manure. Thus Varro says that, " Certain things are to be sown, not with the hope of any immediate profit being derived from them, but with a view to the following year, because, being ploughed in and then left in the ground, they...
Seite 250 - ... of mine own knowledge, in some countries where, in times past, there was one bushel made or used, there is now many loads,- and all risen from the profitable experience which men have found in the same.
Seite 314 - ... the soil with a roller, but this should be followed by a light harrow to secure a mulch on the surface. Where the fields are exposed, and the soil is blown by the wind, an effort should be made to prevent damage from this source. The most effective plan is to lay out the land in long narrow fields so as to have crops that cover the ground in the early spring, such as clover and rye, alternate with the cultivated ground. With the successful growing of clover and possibly alfalfa, the dairy industry...
Seite 85 - Edgerton. Cropped about 60 years, largely to wheat at first, but during the last 40 years it has been fi.rmed in a rotation, consisting of two crops of corn, one of oats and two of clover and timothy, of which the first was cut and the second pastured. The field has not produced good...
Seite 218 - For this purpose a manure spreader, or at least a wagon used for this work only, is very useful and almost necessary. The other method is to allow the manure to accumulate in the stall or covered feeding shed while it is constantly tramped by the animals and kept moist by the liquid excrement, sufficient bedding being used to absorb the excess and to keep the stock clean, and then to haul and spread it on the land when conditions permit. It should not be left, however, to dry out and heat and decompose...
Seite 378 - system " of dry farming has been or is likely to be established that will be of general applicability to all or any considerable part of the Great Plains area ; (2) that any hard and fast rules can be adopted to govern the methods of tillage or of time and depth of plowing; (3) that deep tillage invariably and necessarily increases the water-holding capacity of the soil or facilitates root development; (4) that alternate cropping and summer tillage can be relied upon as a safe basis for a permanent...
Seite 132 - ... favorable that when irrigation water is applied bountiful crops may be secured. But profitable agriculture does not depend solely upon the successful growth of the crop. The costs of production and the relatively higher charges for transportation and distribution are very important factors. And, further, the prosperity of some of the irrigated sections of the West has been more largely due to increases in land values than to the profits of crop production. The costs of crop production may be...
