In my opinion this practice can be followed with profit by 

 the farmers of the states like Minnesota, Iowa and Wisconsin 

 where rainfall is more abundant. The advantage gained by the 

 sprouting of weed seed, the better seed bed gain and the conser- 

 vation of moisture is not to be lost sight of even in these states. 



On land that is fall plowed for small grain and one ought 

 not make a practice of growing grain on spring plowing it is 

 better to double disk early in spring, cross harrow, and sow 

 immediately. It might be that under some conditions single 

 disking will be sufficient. It must be borne in mind that the 

 thing to be accomplished is a finely pulverized seed bed about 

 two inches deep with a solid subsoil contact that will bring 

 moisture up to the dust mulch or within two inches of the 

 surface. For best results, this condition must be established. 

 One of the greatest objections to single disking is the fact that 

 it leaves the ground in an uneven condition covered with ridges. 



Filling Dead Furrows and Leveling Ridges 



In every field of any size can be found several dead furrows 

 and ridges left by the plow in finishing and laying out lands. 

 These should be leveled before planting corn or sowing grain. 

 It is almost impossible to plant and properly cover a row of 

 corn in a dead furrow and the row planted on the ridge is often 

 covered so deep that much of it never comes up. The yield of 

 corn and small grain in dead furrows is always light. 



Figure 1 shows a dead furrow seven inches deep before filling. 



Figure 2 shows the same dead furrow partially filled and 

 manner of filling. 



Figure 3 shows the same furrow completely filled and 

 ground left in level condition. 



A ridge or back furrow may be leveled by driving so that 

 the center of the disk comes on the middle of the ridge thus 

 throwing the dirt outward on either side of the ridge. Once 

 down and back on the same ridge will leave it in a very level 

 condition.
