This upward movement of soil water is what wecall capillary attraction. We all know that when we breakthe crust and form what is called a dust mulch we checkthe loss of water from this source; when checked by themulch, of course, the plant roots have a chance to take it. After every cultivation, new water passages commence 60 CULTIVATION 61 to form, as a result of the up-coming water dampening theunder side of the dust mulch. Repeated cultivations, eventhough it has not rained, break these water passages, andthe result is, you save more moisture for your crop. Cultivate from 8 to 12 times or more if you like. Eachtime you loosen up the surface, you give the crop moreair and also check the Fig. 17.—Planet Jr., cultivator rigged for shallow work, Plants need plenty of air; one reason why a plant will notgrow well on wet land is, because the soil is so full of waterthat the air cannot get in to aid the liberation of plantfood. The cabbage plant simply fills the soil with roots, there- 62 LATE CABBAGE still maintain a good dust mulch. Fig. 17 shows a PlanetJr. cultivator rigged for shallow cultivation. If some one had told you that you could harvest 18tons of cabbage per acre if you would cultivate shallow,or only 12 tons if you cultivated deep, I am sure youwould rig your cultivator for shallow work.
