Kflecte or Holllng I.niul. During tho spring of 1889, a series of observations win mado by tho Wisconsin Wis-consin Experimental Station, which indicated that tho rolling of lnnd has a vory porccptlblo effect upon Its tompornturo. Tho results obtained h.-o summarized us follows: (1) Rolling land mukos tho torn-pcrnturo torn-pcrnturo of tbo soil nt l.C Inchosbolow tbo surfuco from lu to 0g 1. warmer thun similar unrolled ground, and nt throe inches from V to C wnrmor. (2) Rolling lnnd, by firming tho soil, increases ltd power of drawing water to tbo surfneo from bolow, and this influence has been obsorvod to cxtond to a depth of throo or four feet, (it) Tho evaporation of molatiiro Is moro rapid than from unrolled ground, unless un-less the surface soli is vory wet, and then the rovorso is tho enso; the drying effect of rolling bus boon founjl to extend to a depth of four feet. (4) In cases of broadcast needing, gormina-tipi gormina-tipi Is more rpld nntl moro complotn. (6) In tbolr experiments on oats, tho yield stood 01.12 bushels on rolled ground, and 68.89 bushols on tho unrolled un-rolled ground. fC) Tho outs from tho rollod ground wolgbod 2.03 pounds por bushol moro thnn that from tho unrolled un-rolled ground; tho kernol nlso nvorug-cd nvorug-cd larger. But it must bo remembered that this is nn isolated case, and the observations observa-tions should bo repeated, to moro fully ful-ly establish tho conclusion which wo huvo drawn. Tho observations wero all tdcon between 1 and 4 P. M.; tho tompornturo of tho soil was tnkon by moans of cylindrical bulb thormomo-tew, thormomo-tew, which wero ptishod down into tho soil ut dlfToront depths, and allowed to romaln somo time before registering. Tho air temperature- wus tuKon by whirling the thermometer four foot nbovo the ground. His plainly evident evi-dent that rolling tends to raise tho tompornturo of tho noil, and thoro Is no question but what tills tonds to Insure In-sure a healthy gormluntlon of tho seed. |
