Schwermetalle sind von Natur aus in allen Boeden vorhanden. Die jeweiligen Gehalte sind dabei abhangig von den in den bodenbildenden Ausgangsgesteinen vorhandenen Konzentrationen, von den chemischen Eigenschaften der einzelnen Schwermetalle und von der Entwicklungsgeschichte der Boeden. Von einer wirklichen Belastung fur den Boden kann daher nur bei zusatzlich anthropogen verursachtem Schwermetalleintrag gesprochen werden. Der erste Teil des Buches fuhrt in die naturlichen Bodenprozesse sowie in die Chemie der Metalle und deren Analytik ein. Der Hauptteil beinhaltet detaillierte Informationen zu den einzelnen Schwermetallen, deren spezifischen Wechselwirkungen mit Boeden und Pflanzen und zeigt Moeglichkeiten der Melioration bzw. Sanierung auf.

Weeds are botanical thugs, but they have always been essential to our lives. They were the first crops and medicines and they inspired Velcro. They adorn weddings and foliate the most derelict urban sites. With the verve and historical breadth of Michael Pollan, acclaimed nature writer Richard Mabey delivers a provocative defense of the plants we love to hate.

"The best wine book I read this year was not about wine. It was about cider"--Eric Asimov, New York Times, on Uncultivated Today, food is being reconsidered. It’s a front-and-center topic in everything from politics to art, from science to economics. We know now that leaving food to government and industry specialists was one of the twentieth century’s greatest mistakes. The question is where do we go from here.   Author Andy Brennan describes uncultivation as a process: It involves exploring the wild; recognizing that much of nature is omitted from our conventional ways of seeing and doing things (our cultivations); and realizing the advantages to embracing what we’ve somehow forgotten or ignored. For most of us this process can be difficult, like swimming against the strong current of our modern culture. The hero of this book is the wild apple. Uncultivated follows Brennan’s twenty-four-year history with naturalized trees and shows how they have guided him toward successes in agriculture, in the art of cider making, and in creating a small-farm business. The book contains useful information relevant to those particular fields, but is designed to connect the wild to a far greater audience, skillfully blending cultural criticism with a food activist’s agenda. Apples rank among the most manipulated crops in the world, because not only do farmers want perfect fruit, they also assume the health of the tree depends on human intervention. Yet wild trees live all around us, and left to their own devices, they achieve different forms of success that modernity fails to apprehend. Andy Brennan learned of the health and taste advantages of such trees, and by emulating nature in his orchard (and in his cider) he has also enjoyed environmental and financial benefits. None of this would be possible by following today’s prevailing winds of apple cultivation.   In all fields, our cultural perspective is limited by a parallel proclivity. It’s not just agriculture: we all must fight tendencies toward specialization, efficiency, linear thought, and predetermined growth. We have cultivated those tendencies at the exclusion of nature’s full range. If Uncultivated is about faith in nature, and the power it has to deliver us from our own mistakes, then wild apple trees have already shown us the way.

For over four decades, John Coykendall's passion has been preserving the farm heritage of a small community in rural southeastern Louisiana. A Tennessee native and longtime master gardener at Blackberry Farm, Coykendall has become a celebrity in a growing movement that places a premium on farm-to-table cuisine with locally sourced, organic, and heirloom foods and flavors. While his work takes him around the world searching for seeds and the cultural knowledge of how to grow them, what inspires him most is his annual pilgrimage to Louisiana. Drawn to the Washington Parish area as a college student, Coykendall forged long-lasting friendships with local farmers and gardeners. Over the decades, he has recorded oral histories, recipes, tall tales, agricultural knowledge, and wisdom from generations past in more than eighty illustrated and handwritten journals. At the same time, he has unearthed and safeguarded rare varieties of food crops once grown in the area, then handed them back to the community. In Preserving Our Roots: My Journey to Save Seeds and Stories, Coykendall shares a wealth of materials collected in his journals, ensuring they are passed on to future generations. organised by season, the book offers a narrative chronicle of Coykendall's visits to Washington Parish since 1973. He highlights staple crops, agricultural practices, and favourite recipes from the families and friends who have hosted him. Accompanied by a rich selection of drawings, journal pages, and photographs, along with over forty recipes, Preserving Our Roots chronicles Coykendall's passion for recording foods and narratives that capture the rhythms of daily life on farms, in kitchens, and across generations.

Since Antiquity few trees have had a greater impact on the world's culture and economy than the mulberry. The sole food of the silkworm, the leaves of the mulberry brought prosperity not only to ancient China, but to all nations that learned the art of silk production. Mulberry bark was used to make the first paper and the succulent, blood-red fruit of the Black Mulberry has inspired poets from Ovid to Shakespeare. The medicinal properties of all parts of the tree have been known for millennia, making it a tree of choice for medieval monastery gardens, while its anti-diabetic effects are opening exciting avenues of research today. This sumptuously illustrated book tells the remarkable story of the mulberry tree and its migrations from China and Central Asia to almost every continent of the globe. It will appeal to all who wish to know more of the rich history of this emblematic tree.
