Managing Organic Matter in Tropical Soils: Scope and Limitations
Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that soil organic matter declines when land is taken into cultivation, and that the productivity of new agricultural land is governed by fertility contributions from decomposing natural organic matter. The expansion of agriculture to ever new and more fragile lands, particularly in tropical and developing regions, causes environmental degradation with local effects on soil quality, regional effects on landscape integrity and...
The Ecophysiology of Plant-Phosphorus Interactions
Phosphorus (P) is an essential macronutrient for plant growth. It is as phosphate that plants take up P from the soil solution. Since little phosphate is available to plants in most soils, plants have evolved a range of mechanisms to acquire and use P efficiently – including the development of symbiotic relationships that help them access sources of phosphorus beyond the plant’s own range. At the same time, in agricultural systems, applications of inorganic phosphate fertilizers aimed at overcoming phosphate limitation are unsustainable and can cause pollution. This latest volume in Springer’s Plant Ecophysiology series takes an in-depth look at these diverse plant-phosphorus interacti...

Planet Under Stress
This book is the result in bringing together experts from many fields and persuading them to tell us what they have learned about the current changes.
Handbook of Plant Science, 2 Volume Set
Plant Science, like the biological sciences in general, has undergone seismic shifts in the last thirty or so years. Of course science is always changing and metamorphosing, but these shifts have meant that modern plant science has moved away from its previous more agricultural and botanical context, to become a core biological discipline in its own right. However the sheer amount of information that is accumulating about plant science, and the difficulty of grasping it all, understanding it and evaluating it intelligently, has never been harder for the new generation of plant scientists or, for that matter, established scientists. And that is precisely why this Handbook of Plant Science has...

Demography and the Anthropocene
Environmentalists devote little attention at the moment to the size and growth of the human population. To counter this neglect, the monograph (i) includes original graphs showing population size and growth since 1920 in the world as a whole and the United States; (ii) assembles evidence tying the increasing number of people to ecosystem deterioration and its societal consequences; and (iii) analyzes sample-survey data to ascertain whether the current disregard of population pressures by U.S. environmentalists reflects the thinking of Americans generally. However, even if a nation took steps primarily intended to lower childbearing and immigration, the findings of social science research indicate that the steps would not have a substantial, lasting impact. The discussion, which suggests an indirect way by which government may reduce fertility, underlines for environmental scholars the importance of studying their subject in a multidisciplinary, collaborative setting.
