In the historical past of the foreign Plant nutrients Colloquium from its first assembly in 1954, this assembly, the thirteenth Colloquium, is the 1st to be held in Asia and may be the final within the twentieth century. the twentieth century has visible large adjustments within the quantity and actions of mankind. Our inhabitants has elevated from round 1. 7 billion to greater than five. eight billion and technological suggestions have thoroughly altered our lifestyle. by reason of such speedy switch, we face many difficulties together with adjustments in our surroundings of a world scale. yet, whereas nutrition scarcity has been a major problem to mankind all through our historical past, critical nutrients shortages within the twentieth century were restrained to constrained instances and parts. As Lester Brown discusses during this quantity, farmers have elevated foodstuff creation heroically on call for. We, the plant nutritionists can be pleased with our aid to the world's farmers which has helped them make their success attainable. through the twentieth century, the technology of plant food additionally has accomplished nice development as defined by way of Jack Loneragan; it turned validated as a self-discipline firmly established in technology, outlined the chemical parts assisting plant development, and has contributed to advancements in plant construction and environmental caliber, as readers will locate in lots of contributions during this volume.

Example text

But it would be a courageous person who would claim that all essential nutrients have been discovered; wiser to say that the plant does not need other elements at a concentration above the lowest level so far measured. Micronutrients in future food production While it is possible that other chemical elements may be found to be essential in trace amounts, it seems unlikely that any will have as significant an impact on food production as the established essential micronutrients such as copper or molybdenum.

But the agricultural significance of the essentiality of these trace elements was still not generally realized, for in the same review Hoagland (1932), after discussing the beneficial effects of Cu in overcoming various plant diseases in the field, noted "One explanation of the influence of copper under field conditions is that it inactivates some toxic substance developed in the soil, but the phenomenon is still obscure". He advanced a similar explanation in the following year for an effect of Zn in curing "the non-parasitic disease known as 'little leaf' ...

While plant physiologists and chemists had been exploring the responses of plants to trace amounts of various chemical elements, plant pathologists had been frustrated by their inability to find organisms responsible for a number of severe and widespread diseases. These apparently independent lines of research converged when Samuel, a plant patbologist researching the cause of a local outbreak of 'grey speck' disease in oats, and Piper, a chemist working on the response of oats to Mn in water cultures, observed that the "symptoms of Mn deficiency in water-cultures corresponded exactly with the symptoms of Grey Speck disease of oats in the field", and showed that applying manganese sulfate to an oat crop suffering from Grey Speck disease increased grain yield from nothing to nearly 3 t ha- I (Samuel and Piper, 1928, 1929).
