What reading level is The Growth of Wheat Seedlings As Affected By Acid Or Alkaline Conditions book?
To quickly assess the difficulty of the text, read a short excerpt:

Distilled water 0. 129 Potassium sulphate 0. 215 Sodium nitrate . 048 Hydrochloric acid . 257 Potassium chlorid 173 Sulphuric acid . 290 These figures indicate that the least increase was found in the sodium nitrate solution. This is explained by Table 1, which shows that even when sodium nitrate was used alone the solution was alkaline at the end of the experiment, and therefore the further use of calcium carbonate simply acted as a stimulant to a very slight extent.
The weight of the tops, or rather of the stems grown in solutions with and without lime, show no such marked difference, indicating that the appearance of the stems of young wheat seedlings is not always a criterion of the vigor of the plant and therefore of the probable yield of the mature crop.
