WHICH HYBRID FOR YOUR SOIL CONDITIONS? 
PIONEER com hybrids are adapted to a wide range 
of soil types and conditions. They have been tested 
in rich, poor, and sandy soils. PIONEER continually 
carries on extensive experiments with different soil 
types, and recommends only hybrids with wide adapt¬ 
ability. 
If new hybrids show inability to produce well in 
many different soil types—if they do not meet the tra¬ 
ditionally high standards of PIONEER quality — they 
never reach commercial production. 
No corn produces as well on poor soil as it does on 
rich ground, but PIONEER corn ordinarily shows an 
even higher percentage increase over open-pollinated 
corn on poor soil than it does on rich land. 
For low fertility soils, PIONEER recommends an 
earlier maturing hybrid than is ordinarily grown in that 
section. On this type of soil, earlier corn gets along 
faster than later corn and produces maximum yields 
and better quality corn. 
PIONEER hybrid recommendations for sandy soils 
depend greatly on the fertility. High fertility sandy soil 
with normal warm temperature and sufficient rainfall 
often pushes corn along faster than heavy, rich loam. 
Under these conditions, a fairly late corn can be used. 
Ask local PIONEER representatives for specific in¬ 
formation concerning PIONEER hybrid adaptability to 
local soil conditions.
