LIMING ONIONS ^*^ 



How Much Lime? 



If the soil on test shows but moderate acidity-that is, if the color 

 on the til-TeVseale show, yellow to sM.W.tly green-^a ton o l^es^on^

Summary 



1 Of the 114 set onion fields examined in the summer of 1926 a 

 large proportion was found to be loo acid ... grow a mix.mun, crop. 



2 Crop measurements show better yields on the less acid sods. F„r 

 any degree of acidity the yield following tobacco averaged poorer tHau 

 following onions. 



3 Both seed and set onions respond favorably to the use of lime. 



4 Onions grow satisfactorily on la slightly acid soil. Sufficient lime 

 to change the soil acidity to the point where it sbows light green to bliush 

 color with the Soil-Tex is all that is necessary. 



5 Autumn is the best time to apply Unie; but if the s,oil is very 

 acid it is better to apply lime in the spring than not at all. 



6. In using lime for onions, crops that are likely to follow must be 

 given consideration. 



7. On account of black root-rot, tobacco cannot be expected to pro- 

 duce a full crop on a well limed soil.
