About This Book
The text introduces the composition and properties of garden and field soils through simple experiments and classroom exercises, describing clay, sand, silt, organic matter, lime, and water relations; it explains how soil organisms affect fertility, how plant roots access nutrients and moisture, and how cultivation, drainage, and erosion influence land use. Emphasis is placed on observing local soils, practical apparatus and exercises for school pupils, pictorial aids, and the processes by which soils develop and change across landscapes.
