Nitrogen Fixation in Tropical Cropping Systems


Book Description

The second edition of this book, first published in 1991 and intended for students and researchers, contains revised and updated material on the theory and practice of nitrogen fixation in tropical cropping systems. There are 15 chapters in 3 parts. Part I, Introduction, contains 5 chapters on tropical environments (climate, soils and cropping systems), nitrogen fixing organisms, the process of nitrogen fixation, assessment of the role of nitrogen fixation, and cycling of nitrogen in tropical cropping systems. Part II, Tropical crops and cropping systems, comprises 7 chapters on freeliving, root-associated and endophytic nitrogen fixing bacteria of cereal crops and grasses, cyanobacteria and Azolla as green manure for wetland rice, grain legumes, legumes as green manures and cover crops, forage legumes, understorey legumes and shade trees in plantation crops, and nitrogen fixing trees in agroforestry. Part III, optimizing nitrogen fixation, includes 3 chapters on environmental constraints, approaches to enhancement, and future impacts on nitrogen fixation in tropical agriculture. A list of common names and subject index are included.




Oil Palm


Book Description

Oil palms are ubiquitous—grown in nearly every tropical country, they supply the world with more edible fat than any other plant and play a role in scores of packaged products, from lipstick and soap to margarine and cookies. And as Jonathan E. Robins shows, sweeping social transformations carried the plant around the planet. First brought to the global stage in the holds of slave ships, palm oil became a quintessential commodity in the Industrial Revolution. Imperialists hungry for cheap fat subjugated Africa's oil palm landscapes and the people who worked them. In the twentieth century, the World Bank promulgated oil palm agriculture as a panacea to rural development in Southeast Asia and across the tropics. As plantation companies tore into rainforests, evicting farmers in the name of progress, the oil palm continued its rise to dominance, sparking new controversies over trade, land and labor rights, human health, and the environment. By telling the story of the oil palm across multiple centuries and continents, Robins demonstrates how the fruits of an African palm tree became a key commodity in the story of global capitalism, beginning in the eras of slavery and imperialism, persisting through decolonization, and stretching to the present day.
