Book excerpt: "Poplars, aspens and cottonwoods, which are widely distributed over the United States are everywhere subject to serious injury by wood-boring insects. One of the chief of these is the aspen borer, which feeds in the trunks or larger branches, so weakening the wood that the tree is readly broke off by windstorms. Plantations for paper pulp are often completely destroyed. This bulletin give methods of controlling the aspen borer or reducing its damage to a minimum. It is based on extensive studies made in the Pike Peak region of Colorado, but the data in general apply to all regions of the United States where the poplars are native. The introduced Lombardy poplar is very seldom injured, but the commercial cottonwood of the Mississippi Valley seems to be the only native species of poplar which is at all immune to the attack of this index."--Page [2].

Download or read book Alsike Clover written by A. J. Pieters and published by . This book was released on 1921 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Alsike clover is most at home in northern latitudes or at high altitudes. It thrives best in a cool, moist climate. In the Ohio Valley alsike clover is especially adapted to low, wet, fertile land. On such land it will yield heavy crops of first-class hay and will make more than one crop in a season. This crop will grow on "sour" land on which red clover will not thrive. Where it is not possible to apply lime and so insure a stand of red clover, alsike clover may be used. Mixed with red clover on uplands, alsike clover insures a stand on spots where red clover does not catch. Alsike clover is used mostly in mixtures with timothy or other grasses. In such mixtures it improves the hay and increases the yield. The grasses serve to support the clover and make it easier to cut and cure. Alsike clover will endure overflow that would kill most crops. It has been know to grow a year in water-soaked and water-covered soil and make a heavy growth. In the South it is recommended for creek bottoms and other wet lands. It is a good clover to seed in swales or on wet, natural meadows. It volunteers readily and ill spread in such places. Its disadvantages are: (1)On uplands alsike clover grows short and does not make a mass of growth equal to that of red clover. (2)Alsike clover makes no second crop except on low, rich land. (3)On uplands the pasturage after cutting for hay or a seed crop is too small to be useful. (4)There appears to be some danger to horses and mules of a little-known disease said toe result from eating alsike clover."--P. [2]
