To quickly assess the difficulty of the text, read a short excerpt:
The accumulated mass of evidence ad- mits of no doubt that in many cases the apparent lack of fertility of a soil is due to the presence of some organic substance or substances soluble in soil water. This point established, there was studied the effect of fertilizers when added to aqueous ex- tracts from poor soils. A large amount of experimenting has been done on this sub- ject. It has been found that the common commercial fertilizers, as well as many other substances, when added to the soil e...x- tract containing growing plants, sometimes improve the plants, sometimes the contrary. But, in general, those particular sub- stances which improve any given soil for a crop also improve the aqueous extract of the soil for the growth of the same crop plant ; i. c., should a soil be known to respond well to the application of superphosphates when planted to wheat, then the probability is great that the aqueous extract of the soil will be improved as a culture medium for the wheat plant by addition of calcium phosphate.
