Interested in taking a scientific approach to farming?  Give this oldie a try: The First Book of Farming by Charles L. Goodrich.

Although not entirely up to date, The First Book of Farming nevertheless contains many sound principles.  It explores the needs of a plant, examining each of its parts in turn:

• Roots.
• Seeds.
• Leaves.
• Stems.
• Flowers.

Simple experiments encourage the reader to observe for himself the way plants function.  Along the way, practical conclusions are drawn about such things as tilling, cultivation, soil fertility, and more.

The First Book of Farming appears to have been written for older students, but it will provide food for thought for adults of all ages, as well.  Best of all, it’s available free online!
