Uniform plant spacing, seeding depth, and emergence are important factors heavily influenced by both machine settings and soil conditions. Understanding load distribution across the planter toolbar at varying planter settings and soil conditions provide feedback to improve planter performance and achieve desired seed placement consistency. One important soil property that affects opening disc load requirement in creating seed trench is soil texture which relates to soil strength. However, none of the existing methods (soil apparent electrical conductivity (ECa) maps, historic soil maps, and cone penetrometer) provide accurate soil strength data on a high spatial resolution which could be used to optimize planter performance. This study was conducted to (1) quantify the percentage of time row-planters need uplift during planting and (2) quantify opening disc loads using real-time machine control system recorded data across different ECa zones. Results showed that uplift events varied from 13 to 18% with wing and track sections revealed higher instances of uplift. Higher instances of uplift were observed on the non-track section for planter with wing wheels. Results revealed a modest correlation between soil ECa and opening disc load with 435 N more or 12% higher opening disc load applied on high soil ECa zones as compared in low soil ECa zones.

均匀的株距、播种深度和出苗率是受机器设置和土壤条件影响很大的重要因素。了解不同播种机设置和土壤条件下播种机工具栏上的负载分布可以提供反馈，以提高播种机性能并实现所需的种子播种一致性。影响创建播种沟时开口盘负载要求的一项重要土壤特性是与土壤强度相关的土壤质地。然而，现有的方法（土壤表观电导率 (ECa) 图、历史土壤图和锥入度计）均无法提供高空间分辨率的准确土壤强度数据，而这些数据可用于优化播种机性能。本研究的目的是 (1) 量化行间播种机在播种过程中需要提升的时间百分比，以及 (2) 使用实时机器控制系统记录不同 ECa 区域的数据来量化开口盘负载。结果显示，隆起事件从 13% 到 18% 不等，机翼和履带部分显示出更高的隆起事件。在带翼轮的播种机的非轨道部分观察到较高的隆起情况。结果显示，土壤 ECa 和开口盘载荷之间存在适度的相关性，与低土壤 ECa 区域相比，高土壤 ECa 区域所施加的开口盘载荷多 435 N，即高 12%。
