No-Tillage Agriculture

Abstract: The no-tillage cropping system, a combination of ancient and modern agricultural practices, has been rapidly increasing in use. By the year 2000, as much as 65 percent of the acreage of crops grown in the United States may be grown by the no-tillage practice. Soil erosion, the major source of pollutants in rural streams, is virtually eliminated when no-tillage agriculture is practiced. The no-tillage system reduces the energy input into corn and soybean production by 7 and 18 percent, respectively, when compar… Show more

“…In the mid-20th century, recognition that conventional agriculture dramatically accelerated soil erosion led to experimentation with conservation tillage and no-till agriculture (40,41). Over the past several decades, no-till agriculture has been increasingly adopted as a cost-effective alternative to conventional tillage practices.…”

“…This is crucial for designing landscapes and management practices that optimize trade-offs -and tradeoffs are unavoidable. For example, no-till soil management builds soil organic matter and adds trophic complexity to crop fields, but requires chemical weed control (Phillips et al 1980). Bt corn, genetically modified to express Bacillus thuringiensis (Bt) insecticidal proteins that confer resistance to European corn borers, reduces the need for insecticidal sprays, but may affect other lepidopterans as well (Pimentel and Raven 2000).…”

“…Nos primeiros anos de plantio direto, é comum verificar menor disponibilidade de N às plantas quando comparado ao preparo convencional (Phillips et al, 1980;Blevins et al, 1983;Freitas, 1988;Rosso, 1989;Sá, 1992). Várias são as razões atribuídas a este fato: maior imobilização, menor mineralização, recuperação do estoque de MO, dentre outras.…”
