A field study was conducted in Central Alabama from 2009 to 2011 to compare EENFs to standard N sources in a high-residue conservation cotton production system. Nitrogen fertilizers evaluated were: urea; ammonium sulfate; urea-ammonium sulfate; controlled-release, polymer-coated urea (Environmenally Smart Nitrogen, ESN); stabilized urea (SuperU); poultry litter; poultry litter + AgrotainPlus; and an unfertilized control. Detailed plant growth characteristics were determined before defoliation. Generally, standard fertilizers resulted in the largest number of bolls and the highest boll dry weight. ESN tended to perform as well as the standards. Both poultry litter treatments performed poorly during the first year; however, poultry litter + AgrotainPlus was similar to the standards by the third year of study. In this study, the more expensive EENFs produced yields similar to those of standard fertilizers, suggesting that the former may be economically impractical at present. However, EENFs could become viable alternative fertilizer sources given their ability to reduce N loss from agricultural fields via leaching, runoff, and nitrous oxide flux. Additional research is needed on the benefits of EENFs in row-crop production systems.","PeriodicalId":100342,"journal":{"name":"Crop Management","volume":"13 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2134/CM-2013-0050-RS","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71951015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moench var. sudanense] is an increasingly popular forage and cover crop, but farmers have questions about how to manage sudangrass residues for maximum weed suppression. The objective of this greenhouse study was to quantify the relative contribution of sudangrass root exudates (e.g., sorgoleone) and decomposing shoot residue to green foxtail [Setaria viridis (L.) P. Beauv.] suppression across a range of soil mixtures. Green foxtail emergence was reduced by up to 76% by shoot residues and by up to 55% by root exudates. Synergism between decomposing shoot residues and root exudates was observed as the combination of treatments delayed time to >50% green foxtail emergence by 4 to 12 days. Results suggest that the weed suppressive potential of sudangrass is driven by independent and synergistic effects of decomposing shoot residue and root exudates in the soil. Thus, farmers removing sudangrass shoot residue by grazing or haying could experience reduced weed suppressive benefits from this crop. S is often planted as a summer cover crop or forage crop and can be useful for increasing soil organic matter and suppressing weeds when planted at high densities (Forney and Foy, 1985; Weston, 1996). Many studies have demonstrated the capacity for sorghum [Sorghum bicolor (L.) Moench] and sudangrass to suppress germination, emergence, and growth of weeds and other plant species (Hoffman et al., 1996; Nimbal et al., 1996b; Roth et al., 2000; Weston et al., 1989). The mechanism of suppression may be related to a combination of factors, including interplant competition during sudangrass growth (Weston, 1996), physical interference of mulched residues with weed seed germination and growth (Teasdale and Mohler, 1993), delayed nutrient availability to weeds as sudangrass residues are decomposed (Liebman and Davis, 2000), negative soil microbial feedback effects (Klironomos, 2002), or chemical allelopathy (Einhellig and Souza, 1992).
