Hydroponics, the method of growing plants without soil, presents a
feasible alternative to conventional farming in areas which are short on
water supply and limited in agricultural soil.
This book will serve as an indispensable guide for students in the
agriculture sciences, for agriculture instructors and soilless-culture
farmers. It provides up-to-date information on optimal plant nutrition,
deficiencies and toxicities of nutrients, plant growth media, optimal
root environment, environmental control, carbon dioxide requirements,
saline conditions and use of sewage in soilless culture. Other topics
include economic aspects of hydroponics, new growth methods and an
outlook for the future.
