Agricultural food production is facing a great challenge with both unprecedented population growth and dramatic increases in demands for land, water, and nutrient sources. The key to sustainable agriculture will be to better understand the way crops use water and nutrients and improve crop species to be more efficient in using these vital resources.
Improving Water and Nutrients–Use Efficiently in Food Production Systems is a timely resource providing scientists, industry personnel, and advanced studies with an up–to –date overview of the food.
Improving Water and Nutrients–Use Efficiently in Food Production Systems follows a logical progression providing the reader with appropriate context of the issue and efforts being put in place to ensure agricultural sustainability. The first five chapters provide the reader with a global context for the need for efficient use of resources in food production. The following chapters look at various agronomic means, with emphasis on genetics and breeding, by which enhanced water and nutrients–use efficiently can be achieved. The final chapters in the volume cover various efforts in increasing water and nutrient–use in food production systems currently in practice in a range of countries, including China and India as the world's two most populous.
A timely volume,
Improving Water and Nutrients–Use Efficiently in Food Production Systems, fully explores avenues by which we can successfully meet the imperative need of improving water and nutrient use in food production.
