Agricultural, horticultural, forestry, and fodder production, among other endeavors aimed at meeting the needs of a growing population, present significant challenges for the management of natural resources. The pursuit of short-term gains at the expense of sustainability disrupts the delicate balance of the earth's forces and processes, posing a threat to its inhabitants. To address this issue, it is crucial to gain a comprehensive understanding of the principles of soil, plant, and water analysis as applied to horticulture. This understanding will facilitate the attainment of management objectives in harmony with nature. Designed as a textbook, this work will serve to educate learners on these principles, making it a valuable resource for students, planners, faculty members, and anyone else committed to achieving these goals.
