As a rule, water penetrates sand soils much more rapidly than heavier clay soils, he explains. Also soils rich in decayed organic material will hold more water than the same soil without the organic material ma-terial added. "Hollow tubes or spiles made from four laths nailed together are useiul in controlling the amount of water for each furrow," fur-row," recommends the extension horticulturist. "These 14 to 20-inch 20-inch tubes are installed in the bank of the head ditch below c c water level. The volume of wa:c; flowing through the spile is re ulated by a small galvani.-d metal gate that can be moved up and down in saw cuts n the sides of the U.th near rj:e end of the tube," hi explains. |
