28 Progressive Agriculture 



any farming section. More especially is this true 

 under semi-humid conditions. If the principles as 

 outlined under this heading, are carefully observed 

 and carried out, it will go a long way towards, if 

 not completely defeat the ill effect of any drouthy 

 condition on good soil or in any locality with an 

 average annual rainfall of 15 inches or more. 



We shall divide this preparatory tillage into 

 three distinct classes: Spring tillage, for spring 

 and early summer planting; summer tillage for 

 fall seeding of winter wheat, oats or rye; and fall 

 tillage for other crops to follow the one just 

 harvested. 



The continued careful work referred to does not 

 necessarily mean a greatly increased amount of 

 labor, but it has reference more to timeliness and 

 the right kind of work. It is not uncommon for 

 a farmer in the start to put on his field untimely 

 as well as so much work that it is a detriment. 

 Economy in labor adds to the cash profit just the 

 same as increased crop yield, but one must not 

 economize in labor at the cost of a lesser yield in 

 the end. Don't let one dollar's worth of extra 

 timely work loom up so high that you can't see 

 beyond it five dollars more crop yield in return. 



SPRING TILLAGE 



Spring tillage is a somewhat new departure as 

 its object is to make it possible to grow spring 

 planted crops every year in much of the semi- 

 humid section. Our three years of extensive 

 experiments just past indicate that it promises 

 much more than our plan of summer tilling out-
