Assessing the economic benefits and costs of conservation tillage
The economic benefits of the adoption of conservation tillage depend on site-specific factors, including soil characteristics, local climatic conditions, cropping patterns, and other attributes of the overall farming operation. While it is possible to draw some general inferences about components of economic returns and costs, a comprehensive assessment of the net private benefits from greater ...

Crop response to rotation and tillage in peanut-based cropping systems
Production of peanut (Arachis hypogaea L.) in reduced tillage systems has increased in the United States during the past decade. However, interactions of tillage system and crop rotation have not been thoroughly investigated for large-seeded, Virginia market type peanut. Research was conducted at two locations in North Carolina during 1999 to 2006 to compare yield of corn (Zea mays L.), cotton ...

Wheat grain quality response to tillage and rotation with field Pea
Preceding spring wheat (Triticum aestivum L.) with field pea (Pisum sativum L.) can enhance wheat grain yield in a wheat-pea (WP) rotation compared with continuous wheat (WW). The pea-rotation benefits to wheat grain quality are uncertain. A 6-yr study was conducted to determine (i) if grain protein content, kernel weight, and test weight were enhanced for wheat in a WP rotation compared with WW, ...

Dryland crop yields and soil organic matter as influenced by long-term tillage and cropping sequence
Novel management practices are needed to improve the declining dryland crop yields and soil organic matter contents using conventional farming practices in the northern Great Plains. We evaluated the 21-yr effect of tillage and cropping sequence on dryland grain and biomass (stems + leaves) yields of spring wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), and pea (Pisum sativum L.) and ...

Crop productivity and economics during the transition to alternative cropping systems
Many environmental benefits accrue from reducing tillage and increasing crop diversity; however, economic factors often encourage the continued use of intensive tillage and specialized crop production. This study examined crop yields, input costs, and economic returns during the transition to a range of cropping system alternatives in the northern Corn Belt region, including different system ...

Tillage effects on soil carbon balance in a semiarid agroecosystem
Tillage systems may affect soil C sequestration, with a potential impact on crop productivity or organic matter mineralization. We evaluated crop yield, C inputs to the soil, and in situ CO2–C fluxes under no-till and conventional tillage (disk tillage) during the 3- to 6-yr period from the installation of an experiment in an Entic Haplustoll of the Semiarid Pampean Region of Argentina to ...

Fall Tillage Practices And Cover Crops
In my area of Iowa, primarily in Mitchell County, the adoption of strip-till has been huge. There were three or four people that started in the early 2000s, along with my dad, that were pretty vocal about what they were seeing and what kind of benefits they were getting from reducing tillage and going to a strip-till pass. I would love everybody to switch to strip-till and then to no-till down ...

Nitrogen, tillage, and crop rotation effects on carbon dioxide and methane fluxes from irrigated cropping systems
Received for publication December 15, 2008. Long-term effects of tillage intensity, N fertilization, and crop rotation on carbon dioxide (CO2) and methane (CH4) flux from semiarid irrigated soils are poorly understood. We evaluated effects of: (i) tillage intensity [no-till (NT) and conventional moldboard plow tillage (CT)] in a continuous corn rotation; (ii) N fertilization levels [0–246 kg N ...

The Global Food Challenge Explained in 18 Graphics
The world is projected to hold a whopping 9.6 billion people by 2050. Figuring out how to feed all these people—while also advancing rural development, reducing greenhouse gas emissions, and protecting valuable ecosystems—is one of the greatest challenges of our era. So what’s causing the global food challenge, and how can the world solve it? We begin to answer these questions ...

Reduced soil tilling helps both soils and yields
Agriculture degrades over 24 million acres of fertile soil every year, raising concerns about meeting the rising global demand for food. But a simple farming practice born from the 1930's Dust Bowl could provide a solution, according to new Stanford research. The study, published Dec. 6 in Environmental Research Letters, shows that Midwest farmers who reduced how much they overturned the soil -- ...

Soil management practices for sustainable agro-ecosystems
A doubling of the global food demand projected for the next 50 years poses a huge challenge for the sustainability of both food production and global and local environments. Today’s agricultural technologies may be increasing productivity to meet world food demand, but they may also be threatening agricultural ecosystems. For the global environment, agricultural systems provide both sources and ...

Nitrogen contribution from red clover for corn following wheat in western Ohio
Inclusion of a winter legume cover crop into a crop rotation has been suggested as a method to provide a substantial portion of the N requirement of the following crop. While the benefits of winter cover crops such as reduced soil erosion, increased soil organic matter, and increased mulch cover have been well documented, the N contribution to the subsequent crop has shown to be variable. The ...
