244 GRASSES AND HOW TO GROW THEM. 



in time if the spread of the plants is not checked the 

 field is completely possessed by the grass. 



In combating this grass, the following are among the 

 most effective of the measures that may be adopted : 



1. Plough after the crops have been harvested. Work 

 the roots to the surface by using some form of spring 

 tooth or other harrow. Then rake with the horse rake 

 and burn when dry. Follow with one or two crops of 

 corn planted in hills and to which the most thorough 

 cultivation is given. 



2. Sow rye in the autumn. Let the rye mature the 

 following season or graze it which is preferable and 

 follow with a smothering crop as sorghum or corn sown 

 thickly. If necessary grow corn on the same land the 

 next year, managed as outlined above. 



3. Manure the land heavily with reasonably well 

 composted manure. Give to it careful and thorough 

 preparation. Grow on it corn or sorghum, preferably 

 the latter, sown thickly with the drill and as grain is 

 sown and then follow with corn grown as described 

 above. 



4. Plough the land carefully after the gi-ass has made 

 a good start in the spring. AMien ploughing it turn 

 narrow rather than wide furrows. Then use the disk 

 until a good seed bed is formed and then sow barley 

 thickly, using 21- to 3 bushels of seed per acre. Plough 

 again as soon as the barley crop is removed. 



5. Summer fallow the land, ploughing the same or 

 stirring the surface after it has been ploughed with 

 sufficient frequency to prevent the plant from breathing 

 ihrough the leaves for a single season.
