CHAPTER V The Economics of Weeds Every farmer realizes that weeds are among the most important factors in success or failure in agriculture. They occur wherever the soil is cultivated and stand ever ready to take the place of the crop planted if proper tillage, is not given. They not only rob the crop of sunshine and needed space in earth and air, but they also deprive the soil of more or less of its available plant food, draw out its mois- ture, and according to the present belief of some authorities actually poison the soil for other plants. Weeds, however, are by no means to be considered an unmixed evil. In many cases they are rather to be "thought of as a blessing in disguise, for they compel that tillage of the land which is neces- sary for the conservation of moisture and the healthy growth of most crops. " The truth is," writes L. H. Bailey in a famous paragraph, "that weeds always have been and still are the closest friends and helpmates of the farmer. It was they which first taught the lesson of the tillage of the soil, and it is they which never allow the les- son, now that it has been partly learned, to be forgotten. The one only and sovereign remedy for them is the very ss. Meadowsweet.
