Show DISK HAS IMPORTANT PLACE when land Is broken in spring im clement should be Used Rather than plowed for crop dy by PROF PRO F THOMAS SHAW tile the disk has a more important place in dry than in other areas it may bo be used betimes in preparing land for sowing in the absence of the plow it has haa a place on the summer fallow it also has haa a place on stubble lland land sometimes in the autumn and sometimes in the spring I 1 when land is broken in the spring in growing t areas the land should bo be disked rather than plowed for the r next crop the reasons tor for this are y first that the sod burled buried by tile the first plowing flowing will more effectually decay when it tt is allowed to lie two years burled buried than when allowed to lie but one oie second that the sods are thus kept out of the way of the cultivable processes process ess that follow particularly of the harrows until they have reason ably well decayed third on blow land disking does not completely bury the stubbles and this is a decided ads vantage in li holding soils that might otherwise blow through the action of the wind the stubbles thus left incorporated corp orated with the surface soil tend so far to prevent blowing the seed bed Is ie left firm below and in a very dry year such a condition is favorable to the retention of plant growth and therefore is so far favorable to the retention of moisture it would probably be more accurate to say that bo be cause the process Is more favorable to the retention of moisture it is also more favorable to successful plant growth on the summer fallow tile the disk may have a place betimes as well as tile the barrow first it may have a place when weeds become so BO rooted thattie that the harrow cannot dislodge them hem and seel ond in areas where the rains are tor f orential in the manner in which thoy they fall in the summer season weeds frequently ly become so deeply rooted th that t the harrow will not dislodge themon them on summer fallowed fallowes fall owed land this is especially ally true of wild oats and of nearly all it is also true of certain of the volunteer grains in wes western areas to dislodge these it is nee feces es i eary esary to use the disk and in many instances the disk will not pr provo avo sum clent clentry ly effective it is necessary to use somo some kind of an instrument that will cut off the weeds balow the surface of the ground the best implement for this purpose has yet to be invented notwithstanding the disk on summer fallow land will destroy many weeds that cannot be destroyed with the har row jow tile the place for the disking of stubbles in dry areas is an ail important one As soon as the crop has hag been removed much good may result from the disking of the land under many conditions in the first place it opens up the bom packed surface soil so that the rains may enter it when they fall later in the second place it destroys weed growth that would otherwise produce seeds and in the third place it makes atle plowing of the land subsequently much easier than it would otherwise be it would not be correct to say that in all instances the disking of the land after harvest is helpful but it Is helpful in ninny many instances it is not greatly helpful when there Is virtually no moisture in the soil after harvest and when none fall later which sometimes liap happens penH but it Is greatly helpful in destroying weeds when these are growing numerously in the soil it prevents many of them from seeding and it destroys many of them outright the effect which it has upon the easy plowing of the land sub Is very marker marked when soils blow it is IB usually better neither to plow or to disk the land in the autumn in the spring it may be disked the stubbles that are mixed with the surface soil will so far prevent the land from blowing the uso of the disk however has oftentimes been abused by using it when preparing the land for sowing when tb he e plow should bo used instead |
