This book highlights the latest discoveries about the nitrogen cycle in the soil. It introduces the concept of nitrogen fixation and covers important aspects of nitrogen in soil and ecology such as its distribution and occurrence, soil microflora and fauna and their role in N-fixation. The importance of plant growth-promoting microbes for a sustainable agriculture, e.g. arbuscular mycorrhizae in N-fixation, is discussed as well as perspectives of metagenomics, microbe-plant signal transduction in N-ecology and related aspects. This book enables the reader to bridge the main gaps in knowledge and carefully presents perspectives on the ecology of biotransformations of nitrogen in soil.

A critical examination of the engaging voice and multiple stories of Chimamanda Ngozi Adichie on war, feminism, art, ideology, hair, complex human identities and the challenges of multicultural existence. Easily the leading and most engaging voice of her era and generation, Chimamanda Ngozi Adichie has bridged gaps and introduced new motifs and narrative styles which have energized contemporary African fiction since her first novel, Purple Hibiscus (2003). With Half of a Yellow Sun (2007) and The Thing Around Your Neck - Short Stories (2009), she established herself as a preeminent story-teller. Americanah (2013), with ingeniouscraftsmanship addresses the sensitive themes of passionate love, independence, freedom and moral responsibility with extravagant and versatile narrative innovations. Through her writings, she has made herself relevant topeople of all ages - across racial and linguistic boundaries. Her talks, blogs, musings on social media, essays and commentaries, workshop-mentoring for budding young writers, lecture circuit discourses, all enrich her imaginativecreativity as they expand and define her mission as a writer. "We Should All be Feminists" she proclaimed in an essay, giving feminism a "tweak and twist" and suggesting new outlooks in literary theory. Her contributionsto African, Diasporic and World literatures deserve serious analyses, commentaries and interpretations, and this Companion to her work critically examines her creative outputs from her art and ideology, from feminism to war, to matters of myth and perception, and the challenges of multicultural existence and complex human identities.
