Homegrown humus is easy with cover crops! Cover crops are a simple, cheap way to boost your soil's organic matter, to fight weeds, to prevent erosion, to attract pollinators, and to keep the ecosystem in balance. Unfortunately, most information on growing cover crops is written for people who plow their soil every year and are willing to spray herbicides. You can get all of the same benefits in a no-till garden, though, if you're clever. Homegrown Humus details five no-till winners in depth --- buckwheat, sweet potatoes, oilseed radishes, rye, and oats. Profiles of other species suggest gardening conditions when you might want to try out sunflowers, annual ryegrass, barley, Austrian winter peas, crimson clover, cowpeas, or sunn hemp as well. Meanwhile, the book delves into finding cover-crop seeds, planting cover crops in a no-till garden, and easily killing cover crops without tilling or herbicide use. Understanding the C:N ratio of cover crops helps determine how long to wait between killing cover crops and planting vegetables, as well as how to maximize the amount of humus you're adding to your soil. Cover crops are an advanced gardening technique bound to increase your vegetable yields, but are simple enough for beginners. Give your garden a treat --- grow some buckwheat!

Herwig Pommeresche, a German-Norwegian explorer of soil life, graduate permaculture designer and graduate engineer, shares his lifetime of research into humus. Humusphere, translated into English for the first time, digs deep into a myriad of little-known research papers, comparing their findings with the usual conventional methods. Herwig Pommeresche offers an ecologically oriented understanding as a check to the still prevalent chemical-technical agricultural system.

This breakthrough content in this book was long available only as first published in German; it is now available to English-speaking world and is certain to bring a fresh spotlight on the efficacy of vermicomposting. The author brilliantly combines classic and cutting-edge research with real-world experience in gardens and horticultural applications. Farmers and growers of all scale will benefit from learning about the original organic farmer ... the earthworm. Worm composting is a superb alternative to traditional composting methods, which generally suffer from high-energy losses. Working in harmony with the below-surface army of microorganisms, the lowly earthworm is now known to be the true hero in the underground, a soil builder par excellence, not only in nature, but also in garden- and farm-scale composting systems. This lavishly illustrated, in-depth book teaches: Alternatives to conventional composting; The Golden Rules of composting; The worm:mineral theory; Underestimated importance of earthworms; The stages of microbial warming; How to winter worms; Over-fertilization vs. humus; Humus - a substance or a system?; and Mixed cultures, rotation and true organic production.

Now available in English for the first time, this popular 1943 treatise on biology and biologically correct working of soil from the pen of the famous soil scientist Prof. Dr. Franz Sekera, carefully edited and expanded by his wife, scientist Margareth Sekera, over the years, has long been beloved by farmers and soils scientists in its original German. Starting with the basic concepts of tilth and soil structure and moving along to the symptoms of unhealthy soil and the behavior of plants on non-friable fields, Sekera investigates the complex interrelationships in the soil as well as the practical measures to preserve and improve soil tilth.
