Professor Wagner has drawn up, from numerous experiments, the relative manurial values of different nitrogenous manures, which he rates as follows:—
| Nitrate of soda | 100 |
| Sulphate of ammonia | 90 |
| Blood-meal, horn-meal, and green vegetable matter | 70 |
| Finely ground steamed bone-meal, fish-meal, and meat-meal guano | 60 |

| * In the case of neither rice-meal, locust-beans, nor yellow turnips have records of ash analyses been found. For rice-meal the same percentages of phosphoric acid and potash as in Indian corn, and for yellow turnips the same as in swedes, are provisionally adopted; but in all the Tables the assumed results are given in parentheses. For locust-beans no figure has been assumed, and the columns are left blank. | |||||||||
