    Description / Table of Contents: The Potassium Cycle and Its Relationship to Recommendation Development -- Inputs: Potassium Sources for Agricultural Systems -- Outputs: Potassium Losses from Agricultural Systems -- Rhizosphere Processes and Root Traits Determining the Acquisition of Soil Potassium -- Potassium Use Efficiency of Plants -- Considerations for Unharvested Plant Potassium -- Considering Soil Potassium Pools with Dissimilar Plant Availability -- Using Soil Tests to Evaluate Plant Availability of Potassium in Soils -- Evaluating Plant Potassium Status -- How Closely is Potassium Mass Balance Related to Soil Test Changes -- Assessing Potassium Mass Balances in Different Countries and Scales -- Considerations for Selecting Potassium Placement Methods in Soil -- Timing Potassium Applications to Synchronize with Plant Demand -- Broadening the Objectives of Future Potassium Recommendations -- Improving Human Nutrition: A Critical Objective for Potassium Recommendations for Agricultural Crops.
    Abstract: This open access book highlights concepts discussed at two international conferences that brought together world-renowned scientists to advance the science of potassium (K) recommendations for crops. There was general agreement that the potassium recommendations currently in general use are oversimplified, outdated, and jeopardize soil, plant, and human health. Accordingly, this book puts forward a significantly expanded K cycle that more accurately depicts K inputs, losses and transformations in soils. This new cycle serves as both the conceptual basis for the scientific discussions in this book and a framework upon which to build future improvements. Previously used approaches are critically reviewed and assessed, not only for their relevance to future enhancements, but also for their use as metrics of sustainability. An initial effort is made to link K nutrition in crops and K nutrition in humans. The book offers an invaluable asset for graduate students, educators, industry scientists, data scientists, and advanced agronomists.

    Abstract: Weed management Decision Support Systems (DSS) are increasingly important computer-based tools for modern agriculture. Nowadays, extensive agriculture has become highly dependent on external inputs and both economic costs, as well the negative environmental impact of agricultural activities, demands knowledge-based technology for the optimization and protection of non-renewable resources. In this context, weed management strategies should aim to maximize economic profit by preserving and enhancing agricultural systems. Although previous contributions focusing on weed biology and weed management provide valuable insight on many aspects of weed species ecology and practical guides for weed control, no attempts have been made to highlight the forthcoming importance of DSS in weed management. This book is a first attempt to integrate 'concepts and practice' providing a novel guide to the state-of-art of DSS and the future prospects which hopefully would be of interest to higher-level students, academics and professionals in related areas.

    Description / Table of Contents: 1. Introduction -- 2. From Weed Control To Ethics -- 3. Agriculture- A Brief History -- 4. World Population - Three Views -- 5. Agricultures Moral Dilemmas -- 6. Ethics in Agriculture and Other Disciplines -- 7. Seeking Common Ground -- 8. Ethical Puzzles.
    Abstract: I write because I am concerned that I and my agricultural colleagues have avoided addressing the moral dimension of the environmental and social problems we have contributed to. I hope for an exchange of ideas about agriculture's moral dilemmas. I encourage my readers to engage in a collective conversation about the dilemmas and avoid remaining in what Merton calls "the collective arrogance and despair of his own herd." If those engaged in agriculture continue to ignore and fail to realize our common difficulties they will be addressed and resolved by societal pressure and political action, which may not yield the resolution we favor. The book's goal is not to resolve the moral dilemmas raised. It is to raise them and encourage thought and discussion. It will ask but not answer why nearly all involved in agriculture have not addressed the moral concerns voiced by the general public. The agricultural enterprise is committed to the benefits and future success of the present, very productive, chemical, capital, and energy intensive system, which is, in the minds of many, not sustainable. The internal justification invokes the moral claim that they feed the world's population. The question remains whether or not the prevailing moral justification of feeding the world is adequate given all the issues modern, developed country agriculture faces: pesticides in soil, water, and food, cruelty to animals, Biotech/GMO's, corporate agriculture, pollution by animal factory waste, exploitation of and cruelty to migrant labor.
