GETTING THE FARM IN SHAPE The best way to do this blasting is to drive a crowbar downinto the ground within six inches of the desired depth of the hole.In the bottom of the hole made by the crowbar, explode from one-quarter of a cartridge to one cartridge of 40 per cent, dynamite. Donot tamp, as this would cause the explosive to loosen the ground toomuch. 59 r ■■ \l) L- THE THIRD STAGE PREPARING THE LANDFOR CROPS PLOWING WITH DYNAMITEDYNAMITE IN THE ORCHARD
Text Appearing After Image:
PREPARING THE LAND FOR CROPS PLOWING WITH DYNAMITE PLOWS have been used for many centuries to break up thesurface of the earth, so that seeds could be easily planted andgrow better; but from the forked stick of the savage to the greatgang plow of the modern farmer, plows have rarely broken up theground satisfactorily to a depth greater than eight or ten inches. In rich, open soil that is properly fertilized, plowing will breakup the ground sufficiently for many years, but eventually a hardstratum, sometimes called plow hardpan or plow sole, formsjust below the depth to which the plow reaches. This plowsole must be broken up, or the land will begin to fail. Even when plow sole does not exist, land that has been bearing crops formany years is wonderfully improved, if the lower soil is broken upand aerated once in every six or eight years. Land that has only a thin surface soil underlaid by an imper-vious or partly impervious subsoil, sometimes known as hardpan,will not produce crops at
