dirt at the bottom of the mulch up to the top and 

 leaves the firm soil underneath level. Continue 

 this spring tillage at necessary times until the time 

 of planting. It is the open door to better crops 

 every year instead of every other year. Don't 

 let the weeds grow, and get it thoroughly fixed in 

 your mind, that if your tillage efforts are well 

 directed you are continually adding to the 

 elements, and improving the condition necessary 

 for a big crop as you carry this work on into the 

 warm spring weather to the time of planting sug- 

 gested for the different crops referred to later on. 



SUMMER TILLAGE 



Summer tillage should be identical with spring 

 tillage in the start, for recent experience points 

 to the great value of the early thorough work. 

 The plowing, however, in summer tillage should 

 be delayed and the disk used mainly during the 

 early spring. In short summer tillage is a con- 

 tinuation of spring tillage for fall seeding. 



Where summer tillage is planned, the early 

 spring disking should be rather shallow so that 

 later disking can be slightly deeper, thereby 

 throwing a little live moist soil on the top, for 

 the double purpose of keeping the mulch coarser, 

 to prevent blowing, and to keep the surface 

 more open to admit later rains. It is better to 

 use the disk mainly or entirely when possible up 

 to the time of plowing. There again, timeliness is 

 more than quantity of work.
