Building on our knowledge of soil ecology under natural, undisturbed conditions, Soil Tillage in Agroecosystems focuses on how cultivation affects soil and the soil environment. In particular, it highlights how methods of soil tillage can influence soil structure, soil chemical processes, soil borne pathogens, and pest species. Covering the aspects of soil tillage on different taxa, the book concludes with a synthesis of the role of soil tillage in securing a sustainable agricultural environment. It provides the scientific basis for choosing different tillage options to achieve the best possible sustainable base for long-lasting agricultural production.

A Brazilian master novelist in English at last For André, a young man growing up on a farm in Brazil, life consists of “the earth, the wheat, the bread, our table, and our family.” He loves the land, fears his austere, pious father, who preaches from the head of the table as if from a pulpit, and loathes himself as he begins to harbor shameful feelings for his sister Ana. Lyrical and sensual, written with biblical intensity, this classic Brazilian coming-of-age novel follows André’s tormented path. He falls into the comforting embrace of liquor as—in his psychological and sexual awakening—he must choose between body and soul, obligation and freedom.
