This product rebalances manures and other potential sources of odors in barns and animal pens. Zeolites will hold your nutrients in your compost until your plants need it.

This book clearly and authoritatively addresses significant issues of water policy in the western United States at a time when the growing scarcity of western water and the role of the Bureau of Reclamation in the allocation of that resource are becoming increasingly urgent issues. In this scholarly study, Wahl combines his insider's knowledge of the Interior Department's dam-building, regulatory, and water-pricing decisions with an objective analysis of the efficiency dilemma. The study begins by tracing the origins of the reclamation idea and the expansion of subsidies in the program since 1902. The author then recommends major changes in reclamation law and in the Bureau of Reclamation's policies for administering its water supply contracts. He uses four case studies to illustrate the application and potential benefits of his proposals.

Effective participatory water management requires effective co-engineering - the collective process whereby organisational decisions are made on how to bring stakeholders together. This trans-disciplinary book highlights the challenges involved in the collective initiation, design, implementation and evaluation of water planning and management processes. It demonstrates how successful management requires the effective handling of two participatory processes: the stakeholder water management process and the co-engineering process required to organise this. The book provides practical methods for supporting improved participatory processes, including the application of theory and models to aid decision-making. International case studies of these applications from Australia, Europe and all over the world including Africa, are used to examine negotiations and leadership approaches, and their effects on the participatory stakeholder processes. This international review of participatory water governance forms an important resource for academic researchers in hydrology, environmental management and water policy, and also practitioners and policy-makers working in water management.

The fresh, clean taste of New York's water is legendary. Less well known is the fascinating story of the massive program of exploration and construction that was required to achieve such purity. The story of that monumental undertaking is told in Water-Works and illustrated with an astonishing archive of drawings and photographs documenting the design and construction of dams, reservoirs, aqueducts, and tunnels. This complex system brings millions of gallons of water to the city every day from rivers many hundreds of miles away. Kevin Bone, Gina Pollara, Paul Deppe, and students from the Irwin S. Chanin School of Architecture of the Cooper Union spent nine years cataloging and preserving this remarkable archive, which is held by the City of New York Department of Environmental Protection. Essays by Bone, former DEP commissioner Albert F. Appleton, and scholars Peter H. Gleick and Gerard Koeppel trace the history of the system from its beginnings in the mid-1800s to the current construction of City Water Tunnel #3. The story of New York's water system is illuminated in expert detail on the pages of Water-Works, revealing the beauty and power of these magnificent works of public architecture and engineering.
