Show important implement in preventing escape of moisture borne authorities claim when surface 1 smooth it does not hold snow ac well as when left rough other facts by anor it w seem correct to bay that no implement la so patent to prevent the escape of moisture from the soil as the barrow the ways in which it may be used to effect this end are many I 1 these include the harrowing of sum fallow land autumn plowed land land that la plowed late in the spring for imn ideate and land that has been sown to grain both auburon and spring summer fallowes fallowed fall owed land should be first compressed aa soon as it Is plowed it Is then at once harrowed when the management Is what la should be tho harrowing makes a dust mulch this mulch of fine earth dries out to the extent of one or two inches when moisture ascends from I 1 elow aa it always does on the pran ciple of it cannot pass this dust mulch but when rain falls in sufficient it passes down through this dust mulch to the bolst soil below and destroys its effectiveness in order to again be effective at must be renewed and in order to re new it the harrow must be again used the best time to use it Is as toon as the harrow can be used on the soli without the earth adhering to it it it Is not then run over the ground the surface soil will contract in drying with the result tha numerous cracks or fissures will appear in it and through these the moisture will at once begin to escape from below dy harrowing at such a time the dust mulch will bo renewed such renew ri must ba given after each rain of volume to destroy the dust mulch this may not call tor many har as such rains are not very ro quent in scy areas when land Is plowed ta the autumn it should usually be harrowed quito boon after it Is plowed some authorities object to such harrowing they say that when the surface is thus made smooth it does not hold tha enow so well as when it Is left rough is the furrows are by alie plow there la some force in the objection but when the land is rough it dries out more than it it were impacted with the barrow in the spring the ridges OB the creet of the furrow a dry out moro than would be possible it the land were smoothed and impacted with ahe harrow athla Is true of those ridges both tau and spring it would teem reasonable to claim that there is a advantage from harrowing autumn plow ed land land that blows may make an exception to this rule when land la plowed late in the for a crop of millet or other crop that should be eown late it Is important that it shall be bar rowed at nee it Is important tor the reason that the moisture escapes very readily from such land at such a time so rapidly will it escape especially from near the surface that it will eoon become so dry that wed sown on it will not germinate and when it I 1 does not of course the result is crop failure and chaa failure ma be eo complete as to be total the harrow may bo used with ad vantage on crops sown both in the au dumn and in the spring in dry areas when sown in the autumn good results will usually follow from running ive harrow mer the land when the grain Is just beginning to appear the harrow should usually be of the ad custable ju stable type that means that it should be of a type that will admit of tilting the teeth backward at any slant that may be desired whether any subsequent harrowing should be given in the autumn will depend upon tho en of the ground when the ground does not encrust the feces alty tor using the harrow a second lime la not apparent the first time it Is used it more or less renews the aust mulch in the spring it may be used on such land with much advantage when the crop is firmly rooted and of strong growth but should the crop be delicate then bar rowing at such a time must be done with much caution or the harrow may bury the wheat the weeder may be used with more advantage in some tuch instances than the barrow should the ground be impacted it may be advisable to use the spike tooth barrow with the teeth straight n some instances tho harrow should be weighted and there may be ex in in which the disk may be used on such crops with addan lage |
