This book brings together the best advice for cultivating fruit trees, berries and shrubs using biodynamic methods, with the aim of harvesting healthy fruit free of pesticides.\n\nEhrenfried Pfeiffer discusses the principles of tree biology before describing the measures that can be taken to develop a pest-free orchard without the use of chemicals, including soil preparation, the selection of trees for planting, issues of transplanting and pruning, the application of pastes, green cover crops, and pest control.\n\nMichael Maltas ran fruit tree experiments on his biodynamic farm in Missouri for four years. The results are recorded in a highly practical annual spraying schedule for orchards, which is reproduced in this book. A month-by-month calendar gives information on specific methods and controls, based on Maltas's extensive experience.\n\nThis is an invaluable book with practical advice on all aspects of planning and maintaining a healthy orchard.\n\nThis is a thoroughly revised and updated combined edition of 'Biodynamic Treatment of Fruit Trees, Berries and Shrubs' by Ehrenfried Pfeiffer and 'Orchard Pest Management and Spray Schedule' by Michael Maltas.\n\nPublished in association with the Biodynamic Farming and Gardening Association of North America.

La Fertilita' Della Terra - Pfeiffer Ehrenfried - Editrice Antroposofica

Dagli anni Venti di questo secolo Ehrenfried Pfeiffer sviluppò dei metodi alternativi nell'agricoltura e nella valorizzazione dei rifiuti, applicandoli anche nella pratica. Oggi si può vedere che non è più soltanto questione di apportare qua e là correzioni marginali ai metodi produttivi agricoli. Volendo conservare e migliorare la qualità degli alimenti e l'abitabilità del nostro pianeta, occorre piuttosto basare su una più ampia immagine dei regni della natura i metodi di produzione, su di un'immagine che derivi da una concezione spirituale del mondo.

This book describes the history of this now iconic room which represents America's space program during the Gemini, Apollo, Skylab, Apollo-Soyuz and early Space Shuttle eras. It is now a National Historic Landmark and is being restored to a level which represents the day the flight control teams walked out after the last lunar landing missions. \n\nThe book is dedicated to the estimated 3,000 men and women who supported the flights and tells the story from their perspective. It describes the rooms of people supporting this control center; those rooms of engineers, analysts and scientists most people never knew about. Some called it a \"shrine\" and some called it a \"cathedral.\" Now it will be restored to its former glory and soon thousands will be able to view the place where America flew to the moon.

Le prime cinque conferenze sono di Eugene Kolisko (...) In queste conferenze che tenne in Germania nel 1932 l’autore da un quadro complessivo armonico e completo sulle tematiche dell’alimentazione umana in modo limpido e puntuale anche ad una persona che non abbia dimestichezza con l’argomento riuscendo a dare consigli pratici su come debba essere gestito, guidato, creato e curato uno dei gesti più abituali che facciamo ogni giorno spesso senza pensarci troppo e lasciandoci guidare spesso da mode subdole o da falsi ed errati preconcetti. Attraverso una analisi scientifico spirituale Eugene Kolisko ci porta dal piatto fino al campo di provenienza del nostro cibo con analisi limpidissime e consigli semplici e puntuali. Mentre la conferenza di E. Pfeiffer che tenne al Gotheanum nel 1958, tre anni prima della sua morte, conferenza che interpreto come un suo testamento spirituale, fatto nel suo luogo dove lui avrebbe voluto vivere e che doveva essere il cuore del movimento antroposofico, luogo che invece diventò invece un po’ \"la tomba\" dello stesso movimento, grazie ad un lavoro oscuro portato avanti da quello che R. Steiner stesso prima di morire definì \"il gesuita che avete tra di voi\".

While there have been numerous developments and advances in biodynamic agriculture methods since Ehrenfried Pfeiffer first introduced readers to its foundational principles and practices, the key elements remain. Even though this book was originally published in 1938, it remains a foundational text for biodynamic farmers and gardeners. \n\nPfeiffer outlines the basic practices for successfully operating a biodynamic farm, including the principles behind each technique and practice. These methods are backed up by scientific research and data, as well as his own experience as a farmer and researcher, describing what works and what doesn't. Pfeiffer covers soil qualities, making compost, crop rotation, best planting practices, using biodynamic preparations and sprays, and much more -- all with the goal of growing the highest-quality foods by using sustainable methods, working with nature and caring for the earth. \n\nA classic resource for all biodynamic farmers and gardeners.
