The Nutrient Buffer Power Concept for Sustainable Agriculture

The Nutrient Buffer Power Concept, a revolutionary soil testing procedure developed and tested for over more than three decades in European, African and Asian soils, looks at soil testing to devise appropriate and accurate fertilizer recommendations for many field crops, such as, summer rye, wheat, and maize among cereals, red gram among pulses, white clover among fodder crops, and black pepper and cardamom among perennial crops, with a totally new perspective as compared to routine and "text book" methods of soil testing. The center piece of the concept is the accurate quantification of a soil nutrient's "buffer power," which is then integrated into routine soil test data to devise appropriate and accurate fertilizer recommendations.

Dr. Nair has written an excellent and timely book on the nutrient buffer power concept, which he pioneered, and its role in agricultural sustainability. The book will be useful to scientists, students, and professionals in crop and soil sciences and allied fields.

There has been serious decrease in factor productivity on lands that ushered the "Green Revolution" because of unscientific soil fertility management. "Nutrient Buffer Power" is a novel approach for precise soil fertility management. I congratulate Dr Nair for sharing his lifelong experience in plant nutrition and soil fertility management through the remarkable book "The Nutrient Buffer Power Concept for Sustainable Agriculture"

Indian agriculture, is at a cross roads. Highly extractive agriculture of the green revolution has run out of steam. Of the 328.73 mha of geographical area, in India, as much as 120.40 mha has degraded soils, a result of severe carbon depletion due to unscientific soil nutrient management still rooted in "text book" knowledge. Professor Nair's book comes as a breath of fresh air.
