Foliar fertilization is a widely used crop nutrition strategy of increasing importance worldwide. Used wisely, foliar fertilizers may be more environmentally friendly and target oriented than soil fertilization though plant responses to foliar sprays are variable and many of the principles of foliar fertilization remain poorly understood.
The aim of the book is to provide up-to-date information and clarification on the scientific basis of foliar fertilization and plant responses to it with reference to the underlying environmental, physiological and physico-chemical determinants. Information drawn from research, field trials and observational studies, as well as developments in formulation and application techniques, are discussed.
