Mycorrhizal fungi are microbial engines which improve plant vigor and soil quality. They play a crucial role in plant nutrient uptake, water relations, ecosystem establishment, plant diversity, and the productivity of plants. Scientific research involves multidisciplinary approaches to understand the adaptation of mycorrhizae to the rhizosphere, mechanism of root colonization, effect on plant physiology and growth, biofertilization, plant resistance and biocontrol of plant pathogens. This book discusses and goes into detail on a number of topics: the molecular basis of nutrient exchange...

Farmers seldom bare their souls in books, but Walter Moora struggled and wrestled the words in this book from his heart. He offers more than specific descriptions of farming; he tells his life story as a biodynamic farmer and how he learned the lessons of creating healthy ecosystems on the farm through biodynamic preparations and by planting according to the stars.

The author learned early in his...

Amazonian soils are almost universally thought of as extremely forbidding. However, it is now clear that complex societies with large, sedentary populations were present for over a millennium before European contact. Associated with these are tracts of anomalously fertile, dark soils termed terra preta or dark earths. These soils are presently an important agricultural resource within Amazonia and provide a model for developing long-term future sustainability of food production in tropical environments. The late Dutch soil scientist Wim Sombroek (1934-2003) was instrumental in...

"Richard Horan has brought us a welcome view of America to defy the prevailing political and financial nastiness. This is a timely and important book."
--Ted Morgan, author of Wilderness at Dawn

"A lively visit with the dauntless men and women who operate America's family farms and help provide our miraculous annual bounty. Richard Horan writes with energy and passion."
--Hannah Nordhaus, author of The Beekeeper's Lament

"Horan's new book evocatively describes the peril and promise of family farms in America. I loved joining him on this journey, and...

Writer and life-long fisherman Paul Greenberg takes us on a journey, examining the four fish that dominate our menus: salmon, sea bass, cod, and tuna. Investigating the forces that get fish to our dinner tables, Greenberg reveals our damaged relationship with the ocean and its inhabitants. Just three decades ago, nearly everything we ate from the sea was wild. Today, rampant overfishing and an unprecedented biotech revolution...

The vast temperate rainforests of coastal British Columbia are world renowned, but much less is known about the other rainforest located 500 kilometres inland along the western slopes of the interior mountains. The unique region favors the development of lush rainforest communities that incorporate both coastal and boreal elements. In British Columbia's Inland Rainforest, scientists bring together, for the first time, a broad spectrum of information about this distinctive ecosystem. They also consider the ecological consequences of human activities in the rainforest and present strategies...
