What reading level is First Principles of Soil Fertility book?
To quickly assess the difficulty of the text, read a short excerpt:
No stronger argument in favor of rotation of crops is necessary.
Planning a Rotation. — Rotations are in use that cover periods of from two to seven years. In planning a rotation the farmer must be guided by his own condi- tions and requirements in the way of crops. A few general rules may be laid down, however. Every rota- tion should include at least one cultivated or hoed crop, such as corn, potatoes, etc., in order to receive the benefits of such a crop in the way of destroying weeds, impro...ving tilth and setting free potential plant food.
At least one leguminous crop should be included. The legumes are generally deep rooted crops, and in addi- tion to increasing the nitrogen supply of the soil, bring up plant food from the subsoil and leave it where it will be available to the succeeding crop. These deep rooted plants render the subsoil more porous and hasten its disintegration. A crop that is exacting in its food requirements should follow one that is less exacting, or in general terms, the crops should vary as much as possible in their food requirements, manner of growth, root system and the season of the year in which they occupy the ground.
