Page 76 - The conclusions drawn from this study were, in part, as follows: 1. The minimum value of n that should be used in the design of drainage ditches in central Illinois is 0.040. This value obtains at high stages during the summer months in the most carefully maintained channels, where the bottom of the channel is clear of vegetation and the side slopes are covered with grass or low weeds, but no bushes. This low value of n should not be used unless the channel is to be cleared annually of all weeds...

The figures presented show that on this soil a reaction between pH 4.8 and 5.4 should be maintained if potatoes are to be grown on the same soil year after year.
