Lectures On The Inorganic Nutrition Of Plants By D R Hoagland

The first book bearing the title of this volume, Inorganic Plant Nutrition, was written by D. R. HOAGLAND of the University of California at Berkeley. As indicated by its extended title, Lectures on the Inorganic Nutrition of Plants, it is a collection of lectures - the JOHN M. PRATHER lectures, which he was invited in 1942 to give. at Harvard University and presented there between April 10 and 23 of that year - 41 years before the publication of the present volume. They were not "originally intended for publication" but fortunately HOAGLAND was persuaded to publish them; the book appeared in 1944. It might at first blush seem inappropriate to draw comparisons between a book embodying a set of lectures by a single author and an encyclopedic volume with no less than 37 contributors. But HOAGLAND'S book was a compre hensive account of the state of this science in his time, as the present volume is for ours. It was then still possible for one person, at least for a person of HOAGLAND'S intellectual breadth and catholicity of interests, to encompass many major areas of the entire field, from the soil substrate to the metabolic roles of nitrogen, potassium, and other nutrients, and from basic scientific topics to the application of plant nutritional research in solving problems encountered in the field.

The burgeoning demand on the world food supply, coupled with concern over the use of chemical fertilizers, has led to an accelerated interest in the practice of precision agriculture. This practice involves the careful control and monitoring of plant nutrition to maximize the rate of growth and yield of crops, as well as their nutritional value.
