Agricultural, horticultural, forestry and fodder production etc. for the burgeoning population are ever increasing enterprises that impose heavy tasks on the management of natural resources. Short term profitability at the cost of sustainability disharmonises the natural forces and processes resulting in peril of the inhabitants of the earth. To this end an understanding with conviction of the principles of soil, plant and water analysis as applied to horticulture will enhance the realization of management goals in harmony with nature. Intended primarily to be a text book, it will help educate learners to follow those principles. Students, planners, faculties and anyone interested in achieving those goals will find it necessarily useful.
