With recipes for fermented plant juice, nutrient-rich extracts, and IMO using weeds, leaf mold, shells, bones, rock dust, and more Revitalize your garden by making your own biologically diverse inoculants and mineral-rich amendments using leaf mold, weeds, eggshells, bones, and other materials available for little or no cost from local woodlands, fields, restaurants, and markets. Gardener and author Nigel Palmer provides practical, detailed instructions that will be accessible and exciting to every grower who wants to achieve a truly sustainable garden ecosystem, while enjoying better results at a fraction of the cost of commercial fertilizer products. These recipes go beyond fertilizer replacement, resulting in greater soil biological activity and mineral availability while increasing pest and disease resistance, yields, and nutrient density. Recipes range from the very simple-such as using rainwater to extract nutrients from plant residues and using vinegar to extract minerals from bones and shells-to more complex and creative processes for fermenting plant juices and fish and culturing indigenous microorganisms (IMO) to create amendments that supply a broad spectrum of minerals and complex organic compounds. This compact collection of recipes and instructions is inspired by the work of many innovative agricultural pioneers, especially Cho Ju-Young (founder of the Korean Natural Farming method). Palmer supplies extensive data from mineral analysis of amendments he has made using materials from his own garden; this type of detailed data is not available in any other source. The Regenerative Grower's Guide to Garden Amendments also includes a primer on plant-soil interaction, instructions for conducting a soil test and measuring the quality of fruits and vegetables using a refractometer, and guidance on compost, cover cropping, mulching, and other aspects of sustainable gardening.

This book introduces readers to nearly 600 common weeds. In addition to essential information, each chapter includes photos for a specific type of weed to show its morphology in different growth periods, such as seedling, root, flower, fruit, and mature plant. The book also discusses control measures, including agricultural, chemical, physical, biological, and comprehensive methods. The Volume 3 mainly focuses on 252 Species of Dicotyledonous and Monocotyledonous Weeds along with 2 Species of Liverworts and Mosses. With the development of society and economics, weeds have become a recurring problem. In particular, the exotic, invasive, and quarantine weeds have spread dramatically and rapidly. On the other hand, many people, even those who are engaged in weed control, do not (or cannot) distinguish between weeds. Thus there is significant demand for illustrations of weed morphologies, as well as information on their control measures. This book offers a valuable, practical guide for all those working in the fields of crop cultivation, plant protection and quarantine management.

This book explores the sustainability aspect of organic and conventional farming systems, which is commonly categorized into three sub-aspects: social, environmental and economic. The social structure of a given area, organic friendly technologies, soil properties, crop diversification and income are the elements chosen for comparison, and are analyzed using descriptive and statistical methods. In addition, the book assesses the current status of the local organic market in Nepal and field experiments involving the use of various organic means to achieve better production for selected vegetables. Determining the benefits and/or challenges of organic and conventional farming is important to determining the most viable type of farming in the long term, but can be greatly impacted by a given area's specific characteristics (social, environmental, political, etc.), which is why this study focuses on a specific location: the Chitwan district of Nepal, where group conversion to organic farming has existed alongside conventional farming for years. This book offers a useful guide for both practitioners and academic researchers who are interested in organic farming and food security, particularly in developing countries.

This Encyclopedia offers a definitive source on issues pertaining to the full range of topics in the important new area of food and agricultural ethics. It includes summaries of historical approaches, current scholarship, social movements, and new trends from the standpoint of the ethical notions that have shaped them. It combines detailed analyses of specific topics such as the role of antibiotics in animal production, the Green Revolution, and alternative methods of organic farming, with longer entries that summarize general areas of scholarship and explore ways that they are related. Renewed debate, discussion and inquiry into food and agricultural topics have become a hallmark of the turn toward more sustainable policies and lifestyles in the 21st century. Attention has turned to the goals and ethical rationale behind production, distribution and consumption of food, as well as to non-food uses of cultivated biomass and the products of animal husbandry. These wide-ranging debates encompass questions in human nutrition, animal rights and the environmental impacts of aquaculture and agricultural production. Each of these and related topics is both technically complex and involves an - often implicit - ethical dimension. Other topics include methods for integrating ethics into scientific and technical research programs or development projects, the role of intensive agriculture and biotechnology in addressing persistent world hunger and the role of crops, forests and engineered organisms in making a transition to renewable, carbon-neutral sources of energy. The Encyclopedia of Food and Agricultural Ethics proves an indispensible reference point for future research and writing on topics in agriculture and food ethics for decades to come.

This timely book is a compilation of edited articles by distinguished international scientists discussing global warming, its causes as well as present and future solutions. Social and economic growth at global level is measured in terms of GDP, which requires energy inputs generally based on fossil fuel resources. These, however, are major contributors to increasing levels of CO2, causing 15 tonnes of green house gas emissions per capita. Renewable sources of energy offer an alternative to fossil fuels, and would help reduce this to the 2 tonnes of greenhouse gas emissions per capita per annum needed to achieve sustainable growth. As such, the book discusses the next-generation of biofuels and all related aspects, based on the editors' significant investigations on biofuels over the last 30 years. It also presents the latest research findings from research work carried out by contemporary researchers. Presenting global biofuel perspectives, it examines various issues related to sustainable development of biofuels in the contexts of agriculture, forestry, industry and economic growth. It covers the 1st to 4th generation biofuels, as well as the status of biofuel resources and their potential in carbon neutral economy. Offering a comprehensive, state-of-art overview of current and future biofuels at local and global levels, this book appeals to administrators, policy makers, universities and research institutions.

In 1999, the Mount Vernon Ladies' Association inaugurated the Bookshelf series in commemoration of the bicentennial of George Washington's death. Each volume in the ongoing collection will provide a concise overview of a specific Washingtonian topic, offering a wealth of valuable information on such areas as the soldier-statesman's domestic life, political and social interests, and service to the new nation.

This volume provides a fresh historical focus on George Washington as a pioneer farmer actively engaged in a new approach to agriculture: one based on a more scientific attitude toward crops, farm animals, and the land. As Alan and Donna Jean Fusonie examined his correspondence and diaries, the emerging profile of Washington was of a tireless experimenter eager to share his results with visitors and with farmers in other parts of the country and abroad. In his correspondence Washington used the power of his pen to convey important agricultural thoughts. He increasingly expressed his concern about the ruinous agricultural practices of many of his fellow farmers. Washington's complex shift to a more self-reliant and integrated system of agriculture proved him to be an informed, forward-thinking decision maker who focused on the long-term productivity and conservation of his land at Mount Vernon. The authors, also practicing farmers, are intrigued by the similarity between Washington's outlook and that of an increasing number of today's farmers who use more sustainable approaches.

R1,109 Discovery Miles 11 090 Ships in 10 - 15 working days

Towns and villages are sometimes viewed as minor, even quaint, spots, whereas this book boldly reconceptualizes these places as important dynamic environmental 'hotspots'. Multitudes of towns and villages with nearly half the world's population characterize perhaps half the global land surface. The book's pages feature ecological patterns, processes, and change, as well as human dimensions, both within towns and in strong connections and effects on surrounding agricultural land, forest land, and arid land. Towns, small to large, and villages are examined with spatial and cultural lenses. Ecological dimensions - water, soil and air systems, together with habitats, plants, wildlife and biodiversity - are highlighted. A concluding section presents concepts for making better towns and better land. From a pioneer in both landscape ecology and urban ecology, this highly international town ecology book opens an important frontier for researchers, students, professors, and professionals including environmental, town, and conservation planners.

R1,065 Discovery Miles 10 650 Ships in 10 - 15 working days

This volume sits at the cross-roads of a number of areas of scientific interest that, in the past, have largely kept themselves separate - agriculture, forestry, population genetics, ecology, conservation biology, genomics and the protection of plant genetic resources. Yet these areas also have a lot of common interests and increasingly these independent lines of inquiry are tending to coalesce into a more comprehensive view of the complexity of plant-pathogen associations and their ecological and evolutionary dynamics. This interdisciplinary source provides a comprehensive overview of this changing situation by identifying the role of pathogens in shaping plant populations, species and communities, tackling the issue of the increasing importance of invasive and newly emerging diseases and giving broader recognition to the fundamental importance of the influence of space and time (as manifest in the metapopulation concept) in driving epidemiological and co-evolutionary trajectories.

Fungal nanotechnology has great prospects for developing new products with industrial, agricultural, medicinal, and consumer applications in a wide range of sectors. The fields of chemical engineering, agri-food, biochemistry, pharmaceuticals, diagnostics, and medical device development all employ fungal products, with fungal nanomaterials currently used in applications ranging from drug development to the food industry and agricultural biotechnology. Fungal agents are an environmentally friendly, clean, non-toxic agent for the synthesis of metal nanoparticles and employ both intracellular and extracellular methods. The simplicity of scaling up and downstream processing and the presence of fungal mycelia which afford an increased surface area provide key advantages. In addition, the large spectrum of synthesized nanoparticle morphologies and the substantially faster biosynthesis rate in cell-free filtrate (due to the higher amount of proteins secreted in fungi) make this a particularly enticing route. Understanding the diversity of fungi in assorted ecosystems, as well as their interactions with other microorganisms, animals, and plants, underpins real and innovative technological developments and the applications of metal nanoparticles in many disciplines including agriculture, catalysis, and biomedical biosensors. Importantly, biogenic fungal nanoparticles show significant synergistic characteristics when combined with antibiotics and fungicides to offer substantially greater resistance to microbial growth and applications in nanomedicine ranging from topical ointments and bandages for wound healing to coated stents.

R4,805 Discovery Miles 48 050 Ships in 7 - 11 working days

In their rapid colonization of soil exposed by fires, floods, and grazing animals, weeds resemble the human specialists we label Emergency Medical Technicians (EMTs). Weeds are the first responders when disasters occur in nature. They occupy bare soil and prevent erosion by wind and water. In extreme cases such as a landslide, weeds are essential to the healing processes that replace the lost soil. Like a Band-Aid on a skinned knee, weeds protect the land while it recovers. Besides protecting the soil after disaster, weeds provide food for wildlife, and some of them provide food and medicine for people. Able to withstand harsh conditions, weeds will proliferate as global warming and other human impacts intensify. Thus, nature's EMTs will increase while all other plants decline. The book provides a succinct definition of weeds according to their form and function in ecosystem processes. The narrative uses a representative set of weed species from a desert location to illustrate the full range of weed characteristics.

Krishna P Paudel
R2,212 Discovery Miles 22 120 Ships in 10 - 15 working days

The performance of irrigation schemes that carry sediment laden water is often poor. Modern irrigation schemes are increasingly demand based, which means that the water flow in the canals is determined by the crop water requirements. Accordingly the flow in the canal network is not constant as the crop water requirement changes with the climate and the growing stages. Also the inflow of the sediment is not constant throughout the irrigation season. Such schemes, particularly having unlined canals in alluvial soils, are difficult to design and to manage without compromising the flexibility or maintenance cost. This research has made an in-depth assessment on the role of sediment in the design and management of an irrigation scheme by using the data of Sunsari Morang Irrigation Scheme, Nepal. An analysis of the velocity and shear stress distribution across a non-wide trapezoidal canal has been made to derive the correction factor for the sediment transport predictors. An improved approach based on a rational concept of the design of canals for sediment transport is proposed. By using the sediment transport model SETRIC, a water delivery plan has been designed and tested for changing water and sediment inflow conditions that can be implemented with the existing canal infrastructure. The research also shows that flexibility of operation and efficient sediment management are difficult to achieve at the same time. A compromise has to be made and this needs to be reflected in the design. All methods to transport, exclude or extract the sediment are temporary measures and just transfer the problem from one place to the other. A better understanding of sediment movement helps to identify the problems beforehand and to find the best possible solutions.

This book reviews the latest developments in our understanding of microbial endophytes and their potential applications in enhancing productivity and disease protection. It covers all the latest discoveries regarding endophytes, their interactions with plants and application in agricultural productivity and protection. Our understanding of endophytes has increased exponentially in recent decades. These microbes, such as fungi, bacteria, and actinobacteria, establish a symbiotic or parasitic association with plants. A better understanding of endophytic microorganisms may help to elucidate their functions and potential role in developing sustainable systems of crop production and improved protection against biotic stresses. Endophytes play a vital role in plant growth and health promotion. Endophytic bacteria are of agrobiological interest because they create host-endophyte relationships, which can open exciting prospects for newer biotechnological applications. Endophytes have also proven to be a beneficial and sustainable alternative to agrochemicals due to their role in the biocontrol of pests and diseases. Further, endophytes are essential to the production of several secondary metabolites in grasses, in the process of gummosis in trees, and the production of useful metabolites such as alkaloids, pestaloside, cryptocandin, enfumafungin, subglutinols, etc. for the host plant. They are also involved in the production of enzymes, biosurfactants, biocontrol agents and plant growth promoters. As such, it is imperative that we explore these products' industrial applications in the fields of biotechnology, pharmacy and agriculture. This volume will offers a valuable guidance for botanists, microbiologists, biotechnologists, molecular biologists, environmentalists, policymakers, conservationists, and those working for the protection of plant species of agricultural and medicinal importance.
