As ready reference for the student, instructor, and those practitioners that deal with perennial weeds on a daily basis, this book uses 28 weed species to illustrate the ways in which perennial weeds propagate vegetatively. The author has taken care to use examples of perennial weeds that are troublesome on a national scale, or representative of principal agricultural regions within the United States and Canada. This organised and well-written one-of-a-kind text uses both tables and text to assist the reader in identifying each weed species. The text also includes 67 illustrations that highlight reproduction, over-wintering, and perennating parts. Perennial Weeds also corrects some misconceptions in the weed science literature as to whether the perennating organ is a root or a rhizome. Not just another identification guidebook, Perennial Weeds takes the reader through root systems and rhizome anatomy to discuss exactly how perennial weeds propagate, so that eradication can be achieved in the most environmentally sound ways. This book provides the reader with a wealth of information concerning the propagation of perennial grass-like and broadleaf weeds. It emphasises why perennial weeds are so difficult to control and offers suggestions for their control.

Perennial Vegetables

Perennial Vegetables

Nuke the weeds The other key issue in site preparation is removing weeds, especially perennial weeds. In your annual beds you can let the weeds get a bit out of control, because it all gets tilled in at the end of the year anyway.

There is a fantastic array of vegetables you can grow in your garden, and not all of them are annuals. In Perennial Vegetables the adventurous gardener will find information, tips, and sound advice on less common edibles that will make any garden a perpetual, low-maintenance source of food. Imagine growing vegetables that require just about the same amount of care as the flowers in your perennial beds and borders—no annual tilling and potting and planting. They thrive and produce abundant and nutritious crops throughout the season. It sounds too good to be true, but in Perennial Vegetables author and plant specialist Eric Toensmeier (Edible Forest Gardens) introduces gardeners to a world of little-known and wholly underappreciated plants. Ranging beyond the usual suspects (asparagus, rhubarb, and artichoke) to include such "minor" crops as ground cherry and ramps (both of which have found their way onto exclusive restaurant menus) and the much sought after, anti-oxidant-rich wolfberry (also known as goji berries), Toensmeier explains how to raise, tend, harvest, and cook with plants that yield great crops and satisfaction. Perennial vegetables are perfect as part of an edible landscape plan or permaculture garden. Profiling more than 100 species, illustrated with dozens of color photographs and illustrations, and filled with valuable growing tips, recipes, and resources, Perennial Vegetables is a groundbreaking and ground-healing book that will open the eyes of gardeners everywhere to the exciting world of edible perennials.

This book discusses theoretical approaches to the taxonomy of biological systems and theory and mathematical approaches to the problem of plant diversity, cultivation, and the environment. Particular attention is given to theoretical and practical problems of soil and the environmental sustainability of phytocoenosis, with the goal to enhance the productivity of agricultural crops: cereals, legumes, vegetables, and fruit. Providing valuable information on the distribution of chemical elements in the soil–plant system and on the migration of chemical elements in the food chain, this book looks at the composition of the soil and the distribution of elements in the soil–plant system that are manifested as adaptations of plant organism to environmental conditions. With chapters written by acknowledged scientists in the field of genetics, plant selection, ecology, and agro-economy, the book attempts, in many cases, to find consensus between the need to address ways to decrease the excess load on the environment and the need to provide adequately for the human population in agro-developed countries. This book also presents precision farming techniques, including the introduction of differentiated agrochemicals and considering variability of soil fertility and crop conditions. An important element for the conservation and adaptation of plant organism to environmental conditions is the use of physiologically active compounds.
