This book is a timely contribution as it cuts across the water and fertilizer sectors and summarizes the state-of-the-art knowledge on plant nutrition and water management and the challenges we face in achieving the food security component of the Sustainable Development Goals. The authors describe our current understanding of plant nutrient and water interactions, while looking ahead to the best management practices and innovations that will propel crop production to higher levels. The authors also address the issue of sustainability, as only those options that achieve food security and livelihood goals, while also protecting ecosystem services, will be acceptable in the 21st century.
