Micronutrient Fertilizer Use in Pakistan：Historical Perspective and 4R Nutrient Stewardship

Micronutrient research has been an important component of the soil fertility and plant nutrition program in Pakistan since the identification of zinc deficiency in rice in 1969. Since then, considerable progress has been made on diagnosis and management of micronutrient nutrition problems in crops. However, now there is growing R&D evidence that micronutrient malnutrition in humans could be addressed through enriching staple food grains with micronutrients.

This book presents the latest R&D information on micronutrient problems in crop plants/cropping systems and their corrective measures. The current status, the constraints, and economic benefits of using micronutrient fertilizers for optimizing crop productivity and soil resource sustainability are discussed along with estimating future potential requirement of micronutrient fertilizers to optimize crop productivity, produce quality, and soil resource sustainability.

Wide-scale preventable micronutrient deficiencies in human populations originate from micronutrient-deficient soils over which staple cereals and other food crops are grown. This book summarizes R&D information on fertilizer use-based micronutrient biofortification in staple food grains to address "hidden hunger" in human populations. The book also presents the best management practices by which micronutrient deficiencies could be corrected in crop plants in a farmer-friendly manner.
