An Agricultural Geography of Great Britain is a comprehensive account of Great Britain''s agricultural geography. The relationship between agriculture and geography is highlighted, with emphasis on the points of contact between them, including soils, geology, climate, and systems of farming. The farming systems of Great Britain are described, along with the agriculture of Scotland and the border country as well as the agricultural regions of England and Wales. This book is divided into four sections and begins with an overview of the factors affecting the choice of a farming system, including economic circumstances, soil, climate, topography, disease, and the personal preference and individual skills of the farmer. The next section is devoted to Great Britain''s farming systems, which include hill sheep farming and hill sheep with cattle; stock rearing and fattening; dairy farming; horticulture and market gardening, often with some livestock; and pigs and poultry. The agriculture of Scotland and the border country is then considered, followed by a discussion on the agricultural regions of England and Wales. This monograph is intended primarily for agriculturists and geographers as well as students of agricultural geography.

A Practical Course in Agricultural Chemistry provides practical methods in agricultural chemistry. This book discusses the major developments in agricultural analysis, including the atomic absorption technique and gas chromatography. Organized into six chapters, this book starts with an overview of the best instrument to use in soil sampling. This text then discusses a number of various methods for the mechanical analysis of soils. Other chapters consider the methods for the determination of phosphate, nitrogen, and potash in farmyard manure. This book discusses as well the methods for the determination of some of the individual minerals. The final chapter deals with the variation of the color of a solution with a change in the concentration of one of its constituents, which forms the basis of colorimetric analysis. This book is a valuable resource for students taking agricultural chemistry as a subsidiary course as well as for students in farm institutes or agricultural colleges.
