Tillage effects on water use and grain yield of winter wheat and green pea in rotation
Under water-limited conditions, increasing water use efficiency (WUE) is essential for successful crop production. A 7-yr study (1977–1982, and 1985) to evaluate tillage and tillage timing effects on soil water storage, crop water use, and grain yield of winter wheat (Triticum aestivum L.) and spring green pea (Pisum sativum L.) in rotation, was conducted near Pendleton, OR. Treatments included ...

Economic performance of alternative tillage systems in the northern corn belt
While no-till (NT) cropping systems can provide conservation benefits in the northern Corn Belt, adoption has been low due to concerns about potential yield reductions and economic risk. Strip-tillage (ST) systems have been proposed as an alternative that may provide many of the conservation benefits of NT while maintaining productivity and economic returns. The objectives of this study were to ...

Interactive effects of tillage and mineral fertilization on soil carbon profiles
Both tillage and fertilizer management influence soil organic C (SOC) storage, but their interactive effects remain to be determined for various soil and climatic conditions. We evaluated the long-term effects of tillage (no-till, NT, and moldboard plowing, MP), and N and P fertilization on SOC stocks and concentrations in profiles of a clay loam soil (clayey, mixed, mesic Typic Humaquept). Corn ...

Activities of nitrogen-mineralization enzymes associated with soil aggregate size fractions of three tillage systems
Nitrogen mineralization occurring near the soil surface of agroecosystems determines the quantity of plant-available N, and soil enzymes produced by microorganisms play significant roles in the N mineralization process. Tillage systems may influence soil microbial communities and N mineralization enzymes through alterations in total soil C and N. Soil aggregates of different sizes provide diverse ...

Continuous corn response to residue management and nitrogen fertilization
Harvesting corn (Zea mays L.) residue in continuous corn (CC) may require changes in crop management for increased efficiency. Experiments were conducted in Illinois to determine how residue removal and tillage affect surface residue after planting and the response of CC to N fertilization. Partial removal of residue left 21 to 26% surface residue coverage with a chisel plow system, compared with ...

Soil microbial community change and recovery after one-time tillage of continuous no-till
Continuous no-till (NT) results in soil improvements, primarily in the surface 5 cm of soil. One-time tillage may improve NT systems by inverting surface soil with less improved deeper soil. Research was conducted to determine the change in abundance of soil microbial groups after a one-time tillage of NT and their recovery dynamics. Experiments were conducted under rainfed corn (Zea mays L.) or ...

Tillage and fertilizer effects on yield, profitability, and risk in a corn-wheat-potato-wheat rotation
Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific yield risks, or higher nutrient requirements may counteract the positive effects of reduced tillage. This study investigates long-term tillage effects (moldboard plow, and deep and shallow chisel plow) and their interactions with N fertilizer input on yields and ...

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 ...

Wheat and sorghum residue removal for expanded uses increases sediment and nutrient loss in runoff
Received for publication January 16, 2009. Crop residue removal for expanded uses such as feedstocks for cellulosic ethanol production may increase loss of sediment and nutrients in runoff. We assessed on-farm impacts of variable rates of residue removal from no-till winter wheat (Triticum aestivum L.) and plow till grain sorghum [Sorghum bicolor (L.) Moench] on sediment, soil organic carbon ...

Mitigation options for sediment and phosphorus loss from winter-sown arable crops
Received for publication January 20, 2009. Sediment and P inputs to freshwaters from agriculture are a major problem in the United Kingdom (UK). This study investigated mitigation options for diffuse pollution losses from arable land. Field trials were undertaken at the hillslope scale over three winters at three UK sites with silt (Oxyaquic Hapludalf), sand (Udic Haplustept), and clay (Typic ...

Effect of tillage and nitrogen rate on corn yield and nitrogen and phosphorus uptake in a corn-soybean rotation
Understanding tillage, N, and P interactions can contribute to improved N and P utilization and crop response. This study examined the interaction effects of tillage and N rate of two N sources on N and P uptake by corn (Zea mays L.). The study was conducted on Kenyon loam (fine loamy, mixed, mesic Typic Hapludolls) soil at the Iowa State University Northeast Research and Demonstration Farm near ...

Change in Surface Soil Carbon under Rotated Corn in Eastern South Dakota
A diversified crop rotation may reduce fertilizer N inputs for corn (Zea mays L.) and increase soil organic C (SOC). Our objectives were to determine the effects of crop rotation and fertilizer N on soil C within the surface soil (0–15-cm depth). Rotations were started in 1990 on a Barnes sandy clay loam near Brookings, SD. Measurements of SOC began in 1996. Primary tillage since 1996 was chisel ...

Tillage requirements for integrating winter-annual grazing in peanut production: plant water status and productivity
The use of crop rotation systems involving winter-annual grazing can help peanut (Arachis hypogaea L.) producers increase profitability, although winter-annual grazing could result in excessive soil compaction, which can severely limit yields. We conducted a 3-yr field study on a Dothan loamy sand in southeastern Alabama to develop a conservation tillage system for integrating peanut with ...

7N Series PTO Shaft – Replacement of Bondioli & Pavesi PTO Shaft
A 7N Series shaft is a kind of powered take-off (PTO) shaft specifically designed for use by agricultural equipment. It is distinguished through its 7N series yokes. These are a kind of pto u joint that permits the shaft to move to absorb shock. This makes it suitable for equipment subject to vibrations, for instance, balers and harvesters. SevenN Series PTO shafts are offered in a range of ...

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 ...

Root feeding of plants in the conditions of No-Till technology
About 6.5 million hectares of agricultural land in Ukraine are either degraded or unproductive. Above mentioned data are provided by the Food and Agriculture Organization of the United Nations. According to the opinion of other experts, impoverished soils occupy much bigger area and consist about 15 million hectares. The decrease in the amount of humus and the general deterioration of land is ...

Is Conservation Tillage the Future of Agriculture?
Like any business, farmers must manage their farms with one foot in the present and the other in the future. It’s not enough to focus just on yields. We must also consider the impact those yields have on our fields. To ensure sustainable crop production, the implementation of a method like conservation tillage is vital. Conservation tillage is a tilling process that leaves at least ...
