F. W. Johnston is a scientific publication written in the early 19th century. The work aims to bridge the gap between practical agriculture and the sciences of chemistry and geology, advocating for a more scientific understanding of agricultural practices. The text likely delves deeply into the components of soil, the nutrients essential for plant growth, and the chemical processes involved in agriculture. The opening portion introduces the reader to the foundational concepts of agricultural chemistry and geology, setting the stage for a structured exploration divided into parts that cover organic and inorganic substances in plants, soil composition, and the importance of these aspects in farming practices. Johnston emphasizes the need for farmers to understand the chemical nature of soils and plants to improve agricultural productivity. The initial chapters detail organic and inorganic compounds that plants require, the distinction between different types of soils, and how these elements interact with agricultural processes, thus providing readers with critical insights into the scientific underpinnings of successful farming.
