Use of Disk Harrow in Covering Manure 



The value of drawing manure direct from barn to field is 

 being realized more and more every year by farmers of the 

 Northwest. Until recent years, the practice has been to leave 

 stubble land in the fall and scatter manure on it during the 

 winter and spring months. This is to be plowed under in spring 

 for crop. This practice not only delays plowing until spring, 

 which is a bad thing, but gets much of the manure down so deep 

 that some of the value is lost and in case of a dry seed season, 

 shuts off the water supply at the bottom of the furrow slice. 



Much better results are being secured by fall plowing and 

 spreading the manure on top of plowing during winter and 

 spring months. The disk harrow is used in spring for pulver- 

 izing the seed bed and mixing the manure with the surface 

 soil. So well does this work out, that with manure applied at 

 the ordinary rate very little trouble is experienced in working 

 harrows, cultivators, and seeding machinery on land so tested. 

 The illustration opposite shows a disk harrow disking in manure 

 as described above. 



Use of Disk Harrow in Eradicating Quack Grass 



No other tillage implement is so effective in the eradication 

 of quack grass as the disk harrow. When the sod is first 

 turned over, it can be cut up and pulverized with the disk so 

 as to expose the roots to suit wind. This should be followed 

 with a harrow and all roots raked up and burned after the harrow. 

 In about ten days new shoots will be seen coming up on the 

 inverted sod. Now get out the disk and go over the field 

 again, lapping half; repeat the harrowing and burning process. 

 Keep this up as often as any quack stem shows green above the 

 field. It may be found necessary to replow in about six weeks' 

 time, after which the treatment should be the same as described 

 above. One season of this treatment if carefully done, will 

 eradicate the worst fields of quack grass.
