Описание: This manual is part of a global farmer-to-farmer training initiative that aims to increase the knowledge of farmers across the world on soils. It contains a list of soil testing methods that can help farmers assess the condition of their soil in the field as a way to halt soil degradation and as a first step to sustainable soil management.
Indeed, to prevent soil degradation and the loss or reduction of soil functions, including the provision of healthy and nutritious food, there is an urgent need for soils to be sustainably managed. A prerequisite for the sustainable management of soil resources is the availability of reliable information and in particular, of information on how different soil management practices impact soils.
In addition to an inventory of methods, the manual lists the parameters considered critical to soil health. It also includes a section on visual observations using Visual Soil Assessments (VSA) for annual crops and the information that these can provide on the health of a soil.

Описание:
Planning and Evaluation of Irrigation Projects: Methods and Implementation presents the considerations, options and factors necessary for effective implementation of irrigation strategies, going further to provide methods for evaluating the efficiency of systems-in-place for remedial correction as needed.
As the first book to take this lifecycle approach to agricultural irrigation, it includes real-world examples not only on natural resource availability concerns, but also on financial impacts and measurements.
With 21 chapters divided into two sections, this book is a valuable resource for agricultural and hydrology engineers, conservation scientists and anyone seeking to implement and maintain irrigation systems.
Uses real-world examples to present practical insights
Incorporates both planning and evaluation for full-scope understanding and application
Illustrates both potential benefits and limitations of irrigation solutions
Provides potential means to increase crop productivity that can result in improved farm income

Описание: This book deals with the soil fertility aspects of the most important humanitarian problem of the next few decades - feeding all the people due to arrive. It is an outgrowth of a course in advanced soil fertility taught previously by the author to graduate students at Iowa State University.
Описание: Aims to summarize and critically assess the status, development trends and needs of three basic defensive elements that safeguard the quality and environmental safety of soil and water/sediments: early warning monitoring, protection and remediation measures.
Описание: This book presents an analysis of land and water resources in Siberia, initially characterizing the landscapes, their ecosystems, crucial processes, human impacts on soil and water quality, and the status quo of available research.
