Soloviy, W.S. Keeton. – Lviv : Ukrainian National Forestry University Press, Liga-Pres, 2009. − 432 p. – Statistics: fig. 28, tables 67 , bibliography 686 . The modern scientific conceptions and approaches of ecological economics and sustainable forestry are presented in the book. The attention is given especially to the possibility of the integration of these concepts towards solving the real ecological and economic problems of mountain territories and its sustainable development. The ways of sustainability of forest sector approaching have been proposed using the Ukrainian Carpathian Mountains as a case study. The book will be a useful source for scientists and experts in the field of forest and environmental policies, forest economics and management, as well as for the broad nature conservation publicity.

Soil pH, soil organic matter (SOM), total nitrogen (TN), available phosphorus (AP) and potassium (AK) were determined for the samples taken in 2017 and compared to results from the paired samples collected in 1980 by grouping all samples into four cropping systems: continuous paddy fields, new paddy fields developed from uplands, continuous uplands, and new uplands developed from paddy soils. The results show a significant increase in soil pH, AP and AK in all cropping systems, which was, however, coupled with low fertilizer use efficiency. -

Soils – Fundamental Concepts
NRCS Soil: Fundamental Concepts Scoop on Soil Educational CD May 2006 Soils – Fundamental Concepts The Soil In Perspective: A fundamental knowledge of soil science is a prerequisite to meeting the many natural resource challenges that will face humanity in the 21st Century. It is also true that the study of soils can be both fascinating and intellectually satisfying. It is in the soils that we are able to observe all of the principles of biology, chemistry, and physics at work. It is the understanding of these principles which enables us to minimize the degradation and destruction of one of our most important natural resources. Much of our life’s activities and pursuits are related to and influenced by the behavior of the soil around our houses, roads, septic and sewage disposal systems, airports, parks, farms, forests, schools, and shopping centers. It is essential that conservation professionals understand the soils on which we build and design and work. In any field of natural resources, it is important to understand the soil properties which impact the application of technology as we use it to preserve and protect our most basic natural resource, our soils. Soil Defined: We have several definitions of soil depending on the discipline providing the definition: Geologic definition – loose surface of the earth as distinguished from solid bedrock. (Support of plant life not required) Traditional definition – material which nourishes and supports growing plants. (Includes rocks, water, snow, and even air – all of which are capable of supporting plant life) Component definition – mixture of mineral matter, organic matter, water and air. -

Received: 10 October 2009 / Accepted: 24 November 2009 / Published: 1 December 2009 Abstract: The influence of thermodynamics on the emerging transdisciplinary field of ‗ecological economics‘ is critically reviewed from an interdisciplinary perspective. It is viewed through the lens provided by the ‗bioeconomist‘ Nicholas Georgescu-Roegen (1906–1994) and his advocacy of ‗the Entropy Law‘ as a determinant of economic scarcity. It is argued that exergy is a more easily understood thermodynamic property than is entropy to represent irreversibilities in complex systems, and that the behaviour of energy and matter are not equally mirrored by thermodynamic laws. Thermodynamic insights as typically employed in ecological economics are simply analogues or metaphors of reality. They should therefore be empirically tested against the real world.

Ecological Economics: a Progressive Paradigm?
Ecological Economics: A Progressive Paradigm? Kristen A. Sheeran' I. INTRODUCTION Ecological economics constitutes a major paradigm shift in mainstream economics.' Its fundamental vision of the economic system, as circumscribed by ecological limits, challenges the feasibility and desirability of the unlimited growth which underlies economic orthodoxy.2 As an alternative to mainstream economics, ecological economics can appeal to progressive scholars, environmentalists, and others who mistrust mainstream economics, its treatment of environmental issues, and its approach to sustainability. The ecological economics paradigm offers a refreshing and apt perspective on the relationship between economy and ecology for progressives seeking sustainable alternatives to current patterns of economic growth and environmental degradation. But does ecological economics provide additional insights into other issues of critical concern to progressives, and does ecological economics provide a compelling critique of capitalism and vision of alternatives? If ecological economics marks a radical departure from mainstream economics, is ecological economics also a progressive paradigm? To answer these questions, this essay introduces the ecological economics paradigm and examines its progressive underpinnings. Just as no singular description of "heterodox," "radical," or "progressive" economics could capture the diversity of views, methodologies, and interests of progressives working outside of the mainstream of economics, the depiction of ecological economics in this paper fails to capture the variety and nuanced views of ecological economists. 3 What is .

Soil health, or quality, can be broadly defined as the capacity of a living soil to func- tion, within natural or managed ecosystem boundaries, to sustain plant and animal productivity, maintain or enhance water and air quality, and promote plant and animal health. Soil quality and health change over time due to natural events or human im- pacts. -
