Cattle (Bos spp.) producers routinely spread fertilizer or broadcast poultry (Gallus gallus L.) litter to improve forage production. With poultry litter widely available across the southeastern United States and being a cheaper source of plant nutrition than commercial fertilizer when proximal to application sites, the novel application of litter below the soil surface, while costly, allows for greater nutrient retention than broadcasting. Since quantifying costs and benefits of subsurfaced litter is complex, we develop and present a decision support spreadsheet for automated farmscale model comparisons across modes of nutrient management. We compare subsurfaced litter to commercial fertilizer and broadcast litter in userspecific scenarios involving equipment choices (new, used, custom), desired nutrient needs for crops grown, litter nutrient concentration, and interval between litter application given the slowrelease nature of litter compared to commercial fertilizer. Using Visual Basic for Applications programming available with Microsoft Excel, we develop a decision aid that collects relevant userspecific farm parameters that allow customization of output. Performance data of the innovative subsurface application equipment as observed during field operation and published engineering equipment performance standards, combined with cost information, allow estimation of relative performance metrics. Breakeven and sensitivity analyses are performed to identify key equipment modifications or subsidies needed to speed adoption of subsurfacing poultry litter to minimize odor and nutrient runoff externalities experienced with broadcast litter. Results showed that subsurfaced litter can compete with commercial fertilizer on a cost/return basis and especially so in situations where organic farming practices may be targeted. With a longer interval between litter application, enhanced annual capacity utilization of the applicator, and a good match between nutrient needs of crops fertilized and litter nutrient content, the decision aid demonstrated cost savings with subsurfaced litter over commercial fertilizer while being more or less costneutral in comparison to broadcast litter. The decision aid lends itself to estimating operationspecific subsidies needed to encourage adoption of subsurface application of litter with the intent to reduce nutrient runoff and odor externalities. Alternatively, the sensitivity analyses pinpointed the need to enhance the performance rate of subsurface application that may be achievable by increasing the implement’s width.
牛(Bos spp.)生产者经常施肥或放养家禽(Gallus Gallus L.)产仔以提高饲料产量。随着家禽垃圾在美国东南部的广泛使用，在接近施用地点时，它是一种比商业肥料更便宜的植物营养来源，在土壤表面以下施用垃圾的新方法虽然成本高昂，但比放养更能保持养分。由于量化地表下凋落物的成本和收益是复杂的，我们开发并提出了一个决策支持电子表格，用于跨营养管理模式的自动化农场规模模型比较。我们将地下凋落物与商业肥料和播撒凋落物在用户特定情况下进行了比较，包括设备选择(新的、使用过的、定制的)、作物生长所需的养分需求、凋落物养分浓度和凋落物施用间隔，因为凋落物与商业肥料相比释放缓慢。使用Visual Basic for Applications编程和Microsoft Excel，我们开发了一个决策辅助工具，它收集相关的用户特定农场参数，允许自定义输出。在现场操作过程中观察到的创新地下应用设备的性能数据和公布的工程设备性能标准，结合成本信息，可以对相对性能指标进行估计。进行盈亏平衡分析和敏感性分析，以确定加速采用地下家禽垃圾所需的关键设备修改或补贴，以尽量减少放养垃圾的气味和营养流失外部性。结果表明，在成本/回报的基础上，地下凋落物可以与商业肥料竞争，特别是在可能针对有机农业实践的情况下。由于施用凋落物的间隔时间较长，施施者的年产能利用率提高，并且施肥作物的养分需求与凋落物养分含量之间的匹配良好，决策辅助表明，与商业肥料相比，地下凋落物节省了成本，而与撒播凋落物相比，成本基本中性。决策援助有助于估计为鼓励采用地表下施用凋落物以减少养分流失和气味外部性所需的具体业务补贴。另外，灵敏度分析指出，需要通过增加工具的宽度来提高地下应用的性能。
