What reading level is First Principles of Agriculture book?
To quickly assess the difficulty of the text, read a short excerpt:
47 Mcui TIT?- ; h-needed fertilizer soda. The chief source of supply is from salt-mines, such as exist so largely in Cheshire, and also from the evaporation of sea-water. Good samples of Cheshire salt contain as much as 98 per cent, of chloride of sodium; but the salt obtained from sea-water usually contains chloride of magnesium, and it is more than usually disposed to become moist, which renders its distribution more difficult. Its action as a fertilizer is in many respects peculiar, by reaso...n of its apparently inconsistent influ- ences, for in many cases we see it giving a decided check to vegetable growth, and yet thereby increasing the production of corn. For some crops, such as the mangel wurzel, salt is a direct requirement of the plant as food. Beans, cabbages, and onions also appear to flourish with liberal supplies. The analysis of the ash of mangel wurzel shows considerable varia- tion in the quantity of salt present. According to Way and Ogston the average of four analyses of the bulb showed a variation of from 10 per cent, to 49*51 per cent, of salt in the ash, and an average of 24*55 per cent.
