This reference guide is designed to improve general understanding of the best management practices for the use of water and fertilizers throughout the world to enhance crop production, improve farm profitability and resource efficiency, and reduce environmental impacts related to crop production.

The book cuts across the water and fertiliser sectors and summarises 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 book also addresses 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.
