Show DEEP PLOUGHING AND SUB-SOILING. The matter of sub-snlltng Is not well understood by the nxernge fnrmer, too many pt rsona thinking Hint diep ploughing nnd suh-solllng nnswer the same purpose The fait is that In limnj soils the deep ploughing would be ilecl.lt tll detrlmeiitnl, while it Is dllllcult to contclve of n case wherein sub-soiling Is not beneficial The reason rea-son uli) It Is not ulwns advisable tn tut n u furtow ten or twelve lnchea deep la that such ploughing would often bring up soil that la lifeless nml lacking lack-ing In humus or oignnlc matter. Ihla soil fiom a depth would require nt least ime siason of aeration before being fit for n seed lml. In the meantime such soil would Im liable to bake ami track. Again by deep ploughing tho metnw surface soil Is hurled so deep as to place the rich plant food beyond the itnch of sh ilolw rooted plants On the other hand when the surface Is (.Uriel to n depth not exceeding elL'ht Inches nnd the sub soil below la loosened to a llko depth, the fertile soil li mains on toj. anil the subsoil Is open and randy to absorb moisture. Moreover, More-over, the continual loosening of the suli-soll inusea the plant food mid the air tn dewend until utter a few eni there will lie alxten inches of rich soil that mn lie ploughed tn the full depth i very )ear In addition to the above leitBons, Ihe speilal benefit Hint the Irrigated Ir-rigated farm receives Is In the Increased iniwclty fnr absorbing and holding water foil tlmt Is loosened tn a depth nf slxten Inches will not only absorb double the amount of water Hint will soak into the eight-Inch ploughing, but the vvntei going tn the lower depth will lemnln in the siMI more tiinn tluee times us long.
