To quickly assess the difficulty of the text, read a short excerpt:
This last form has no power to attack ammonia, but must have a nitrite for its food, and the previous work of breaking down the organic matter and the release of ammonia must be done by other plants. Both of these organisms are present in enormous numbers in any cultivated soil, but most largely, of course, in those having a large amount of nitrifiable organic matter. The work of both organisms goes on together. Nitrogen added to the soil in the form of ammonia must go through the oxidation pro...cess conducted by these minute plants, and be changed into a nitrate before our crops can use it. This shows the importance of having nitrogen present in a fertilizer in two forms. Nitrate of soda, for instance, is already in the form of a nitrate, and plants can use it at once if they are in active growth ; if not used at once it soon washes from the soil. Then the supply of nitrogen must be kept up through the nitrification of organic ammonia in the form of cotton seed meal, fish scrap, castor pomace, tankage, etc.
