Land may be made to retain its fertility for generations

Since cowpeas, clover, and alfalfa add atmospheric nitrogen to the soil and at the same time are the best feeding-materials, it follows that these crops should hold an important place in every system of crop-rotation. By proper rotating, by proper terracing, and by proper drainage, land may be made to retain its fertility for generations.

EXERCISE

2. What is meant by the protein of a food?

3. Why is it better to feed the farm crops to animals on the farm rather than to sell these crops?
