What reading level is Agricultural Pamphlets book?
To quickly assess the difficulty of the text, read a short excerpt:
Humus not only absorbs and retains moisture from the atmosphere, but also ammonia ; and this it does in virtue of its porosity, no less than in virtue of the chemical affinity which the humic and ulmic acids found in humus possess for ammonia.
3. The organic remains in soils contain nitrogen, and, on gradual decomposition, give rise to the formation of ammonia, which at once is fixed by the humic acids generated at the same time during the decomposition of the organic matters of the soil.
4. Or...ganic matters, in order to be decomposed, must be brought into contact with atmospheric air, the oxygen of which changes them by degrees into brown and black humus, both of which include various organic combinations, characterised by great avidity for absorbing oxygen from the atmosphere, by which they are finally resolved into carbonic acid. Organic matters thus furnish a continual source of carbonic acid in the soil, and afford thereby organic food to the plant, which food appears to be highly beneficial in the earliest stages of vegetable life, before the green leaf is fully formed, and the more mature plant can avail itself of the carbonic acid of the atmosphere.
