Paperback. Condizione: New. Print on Demand. This book is a collection of lectures on investigations carried out at the Rothamsted Experimental Station, delivered by famed scientist Robert Warington before the Association of American Agricultural Colleges and Experiment Stations in Washington in the year 1891. As the first series of such lectures, the author had the privilege of reading all of them to the man who inspired their creation, Sir John Bennet Lawes, prior to delivery. Sir Lawes played a pivotal role in establishing the trust through which Rothamsted passed under its new management, and also generously provided some hitherto unpublished results for inclusion in the lectures. Given the importance of nitrogenous matter in determining soil fertility and crop yields, a primary focus of these lectures is to convey the author's significant research into this topic. Warington examines the nature of this matter, its origins, and the intricate interplay of factors that lead to either its increase or decrease in the soil. Historically, it was the development of artificial fertilizers by the author and Sir Lawes, beginning around 1840, that instigated the comprehensive study of soil chemistry and plant nutrition that continues at Rothamsted to this day. However, this book conveys findings that are still relevant to modern agriculture, examining in granular detail the exchange between the atmosphere, plants, and soil that makes nitrogen available to plants and that can significantly impact crop health and productivity.
