Green Spring Farm by Nan Netherton and Ross DeWitt Netherton.
The book is about farming in colonial America. Here is an excerpt from the book:
With the effort to establish scientific farming came experiments in crop rotation, with use of clovers and grasses interspersed between other crops, increased use of manure and artificial fertilizers, better plows and methods of soil preparation, and more attention to control of erosion. Interest in improving farm animals during this period led to introduction of merino sheep and new breeds of mules.
