To quickly assess the difficulty of the text, read a short excerpt:
It is obvious that the carbonic acid contained in the air of the soil, being from twenty to one hundred or more times more abundant, relatively, than in the common at- mosphere, must act in a correspondingly more rapid and energetic manner in accomplishing the solution and disin- tegration of mineral matters.
c. The organic acids of the humus group probably aid in the disintegration of soil by direct action, though our knowledge is too imperfect to warrant a positive conclu- sion. The ulmic and... humic acids themselves, indeed, do not, according to Mulder, exist in the free state in the soil, but their soluble salts of ammonia, potash or soda, have acid characters, in so far that they unite energetical- 140 HOW CROPS PEED.
ly with other bases, as lime, oxide of iron, etc. These alkali-salts, then, should attack the minerals of the soil in a manner similar to carbonic acid. The same is probably true of crenic and apocrenic acids.
d. It scarcely requires mention that the ammonia salts and nitrates yielded by the decay of plants, as well as the organic acids, oxalic, tartaric, etc., or acid-salts, and the chlorides, sulphates, and phosphates they contain, act upon the surface soil where they accumulate in the manner al- ready described, and that vegetable (and animal) remains thus indirectly hasten the solution of mineral matters.
