Greg begins with a description of the "old" agricultural system, involving a summer fallow and ploughing and details a list of its disadvantages. He then follows with an outline and explanation of his new system, which requires the land to only be ploughed once and increases the produce. With an appendix pointing out how the infant turnip may be protected from insects by a critical application of lime.
