Show PLAN FOR SAVING RAINFALL Plow the Field as Soon as Crop Has Been Harvested and Follow This Up With Drag. Moisture conservation is not a sure cure for crop failure. Every farmer, though, knows what three or foui inches of additional rain during a dry season will do, and when it is realized that it is possible and feasible to conserve con-serve moisture to that extent it begins to look as though the saving of moisture mois-ture from one year to another would help some in case of short rainfall. Three or four Inches of rain carried over from one season to the next means three or four hundred tons ol water an acre in the subsoil water enough to carry a growing crot through any ordinary dry weather. II is possible to carry even more than this from one year to another, says A. H Leldlgh, assistant professor ol crops at the Kansas agricultural college. col-lege. How can the rainfall be saved 7 Plow the field as soon as the crop has been harvested. If it Is spring or summer, sum-mer, follow the plow with a drag. The rains will soak Into the soil Instead In-stead of running off the surface or evaporating. Fall plowing should not be dragged, as there Is danger of the soil either packing or becoming dry and blowing. The extra expense ol following such a plan ought not to cost more than a dollar an acre at most. Many places it could be done at a much smaller cost. It pays big Interest on the Investment even at the higher figure. |
