“…As suggested by others (Touchton et al 1982(Touchton et al , 1984Hargrove 1986;Blevins and Frye 1993;Reeves et al 1993;Abdul-Baki et al 1997;Sainju et al 2002), for reduced tillage systems that include winter legume cover crops, the crop fertilizer requirement can diminish with successive seasons, and fertilizer rates can often be appreciably reduced. This may be due directly to the release of cover crop N, as well as indirectly through build up of organic matter and improved recycling of N inputs.…”

In spite of potential benefits and positive assessments of reducing primary tillage operations, only a small part of irrigated row crops is currently managed using reduced tillage, for reasons that include concerns about its agronomic suitability for certain crop rotations. Three years of a tomato/corn rotation under standard and no-tillage management were used to understand the fate of a fertilizer and cover crop nitrogen (N) application. Uptake of both inputs was reduced under no-tillage during the year of application, in this case a tomato crop. As a result, more input N was retained in the soil in this system. The initial challenge of reduced tomato yields diminished as no-tillage management remained in place and the soil N reservoir developed. Corn production was not affected by tillage treatment. Inclusion of a legume cover crop increased the amount of fertilizer N retained in the soil over time, more so under no-tillage than under standard tillage, emphasizing the benefit of cover crops in reducing the amount of fertilizer required to maintain productivity. While acceptance of reduced tillage ultimately depends on economic performance, the results of this study support its agronomic viability for irrigated row crops.

“…Winter annual legumes, such as crimson clover (Trifolium incarnatum L.) and hairy vetch (Vicia villosa Roth. ), are utilized as N sources for summer crops (Touchton et al, 1984;Brown et al, 1985;Reeves, 1994). Sunn hemp, a summer legume, has also been shown to decrease corn N requirements in the southern USA (Balkcom & Reeves, 2005).…”

“…In the southeastern USA, legume crop residues have been evaluated in conservation tillage systems to improve crop production and enhance soil physical characteristics (Mitchell & Teel, 1977;Touchton et al, 1984;Oyer & Touchton, 1990;Reeves et al, 1993;Torbert & Reeves, 1996). Typically, legumes are planted after harvest in the fall, terminated in the spring, and a summer crop is planted into that residue.…”

Leguminous winter cover crops have been utilized in conservation systems to partially meet nitrogen (N) requirements of succeeding summer cash crops, but the potential of summer legumes to reduce N requirements of a winter annual grass, used as a cover crop, has not been extensively examined. This study assessed the N contribution of peanut (Arachis hypogaea L.) residues to a subsequent rye (Secale cereale L.) cover crop grown in a conservation system on a Dothan sandy loam (fine-loamy, kaolinitic, thermic Plinthic Kandiudults) at Headland, AL USA during the 2003-2005 growing seasons. Treatments were arranged in a split plot design, with main plots of peanut residue retained or removed from the soil surface, and subplots as N application rates (0, 34, 67 and 101 kg ha -1

Leguminous crops, particularly winter annuals, have been utilized in conservation systems to partially meet nitrogen (N) requirements of succeeding summer cash crops. Previous research also highlights the benefits of utilizing summer annual legumes in rotation with non-leguminous crops. This study assessed the N contribution of peanut (Arachis hypogaea L.) residues to a subsequent cotton (Gossypium hirsitum L.) crop in a conservation system on a Dothan sandy loam (fine-loamy, kaolinitic, thermic Plinthic Kandiudults) at Headland, AL during the 2003-2005 growing seasons. Treatments were arranged in a split plot design, with main plots of peanut residue retained or removed from the soil surface, and subplots as N application rates (0, 34, 67, and 101 kg ha −1 ) applied in fall and spring. Peanut residue did not influence seed cotton yields, leaf N concentrations, or plant N uptake for either growth stage or year of the experiment. There was a trend for peanut residue to increase whole plant biomass measured at the first square in two of three years. Seed cotton yields and plant parameters measured at the first square and mid-bloom responded favorably to spring N applications, but the recommended 101 kg N ha −1 did not maximize yields. The results from this study indicate that peanut residue does not contribute significant amounts of N to a succeeding cotton crop, however, retaining residue on the soil surface provides other benefits to soils in the southeastern U.S.
