Book Description
Soil Essentialsis a practical reference for farmers and land managers covering soil issues commonly encountered at the farm level. Written in a straightforward style, it explains the principles of soil management and the interpretation of soil tests, and how to use this information to address long-term soil and enterprise viability. This book demonstrates how minerals, trace elements, organic matter, soil organisms and fertilizers affect soil, plant and animal health. It shows how to recognise soil decline, and how to repair soils affected by nutrient imbalances, depleted soil microbiology, soil erosion, compaction, structural decline, soil sodicity and salinity. The major problem soils “ sodic soils, light sandy soils, heavy clay soils and acid sulphate soils “ are all examined. With this information, farmers and land managers will be able to consider the costs and financial benefits of good soil management.

Book Description
Oceans and Aquatic Ecosystems theme is a component of Encyclopedia of Natural Resources Policy and Management, in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The theme guides the reader through various pathways followed by surface water on earth. It describes the dominant processes that govern how organisms interact with water and with each other, and how they in turn can modify water properties. This knowledge is important for humanity. Indeed, only by understanding our actions impacts upon water, and the animals and plants living in it, can we learn to exploit water, marine and fresh-water habitats and the living organisms, without destroying the resources on which our livelihood and very survival depend. The Theme on Oceans and Aquatic Ecosystems discusses matters of great relevance to our world such as: Freshwater Wetland Resources and Biology; Problems, Restoration and Conservation of Lakes and Rivers; Coastal Regions; The Oceans and Seas; Oceanic Islands These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Book Description
Agroecology is the science of applying ecological concepts and principles to the design, development, and management of sustainable agricultural systems. The Ecology of Agroecosystems highlights a collection of alternative agricultural methodologies and philosophies and provides an interdisciplinary approach that bridges the sociopolitical and historical context of agriculture. It includes the technical issues in a serious and ecological fashion and captures the complex merging of ecology, agriculture, politics and economics in both a historical and contemporary context. Readers will learn not only about the ethical and moral elements related to producing food of questionable quality while possibly impairing the environment, but also about the soil chemistry involved.

Book Description
This publication explains the "why" and "how" of classical biological control in forestry, and addresses the potential risks associated with such programmes. Written by a team of experts, it provides general theory and practical guidelines, featuring 11 case studies of successful implementation efforts worldwide. While insect pests already damage millions of hectares of forest worldwide each year, the extent of such damage is increasing as the impacts of climate change become more evident and as international trade grows, facilitating the pests’ spread. Classical biological control is a well-tried, cost-effective approach to the management of invasive forest pests which involves the importing of "natural enemies" of non-native pests from their countries of origin with the aim of establishing permanent, self-sustaining populations capable of sustainably reducing pest populations below damaging levels.
