Modern crop production depends on addition of fertilizers to supplement natural soil fertility.
Historically, crop production management has progressed to more intensive methods. Precise nutrient
management has become essential for sustainable agricultural production systems. Addition of
all plant nutrients must be considered for optimum crop production. With intensification of crop
production, the need for micronutrient fertilization increases. Boron deficiency has been recognized
as one of the most common micronutrient problems in agriculture.
