INTRODUCTION

Dr Cooper devised the Nutrient Film Technique and the existence of NFT cropping is to a great extent due to his persistence and determination in the face of intial scepticism. With the spread of NFT, his experience has become international, ranging from NFT tomato and cucumber cropping under artificial light in Alaska to the production of NFT hybrid Napier grass for feeding the milking herds of India. He has a unique understanding of NFT cropping which is evident in this book.
First published in 1979, The ABC of NFT quickly established itself as the 'hydroponic NFT bible' throughout the world. It can be fairly said that many of the world's commercial NFT growers used this visionary work as their inspiration. Today, Dr Cooper's extraordinary vision has become a reality. In this new edition, Dr Cooper looks at the development of NFT, and challenges conventional hydroponic thinking in a forward that suggests that further research work is needed to explore the use of non-chemical nutrition.
The ABC of NFT is arguably one of the most important documents published in hydroponics literature. For the commercial NFT grower, it is essential reading.

ABOUT THE AUTHOR

Dr Allen Cooper was commissioned into the Royal Engineers in 1942, seconded to the Indian Army and served with the Royal Bombay Sappers & Miners until 1946. He then read for a B.Sc. in Horticulture at Wye College from 1947-1950, after which he was awarded a post-graduate scholarship to study plant pathology at Reading University from 1950-1953 for his Ph.D. In 1953, Dr Cooper was appointed plant physiologist at the Chesnut Experimental Station, and in 1955 he joined the staff of the Glasshouse Crops Research Institute. In 1978 he became Managing Director of Nurtient Film Technology Ltd., one of the companies of Ariel Industries of Leicester. He retired in 1989 at the age of 65 years.
