The proposed grant is to purchase a unique piece of equipment that will allow my research group to continue studying how plant roots function belowground in managed or natural ecosystems. Briefly, clear tubes are inserted into the ground and a miniature video camera with 100X zoom is inserted into the tubes and root images are captured on a portable laptop in the field. Root images are collected monthly or weekly from the exact same location in the tube to determine which roots have grown and which roots have died in order to estimate belowground productivity. These root images are processed in the laboratory through an image analysis program which traces the roots in the images and then computes productivity. This equipment will help graduate students investigate the role of fine roots in carbon sequestration and increase our understanding of how roots function belowground.

拟议的赠款是购买一个独特的设备，这将使我的研究小组继续研究植物根系如何在地下管理或自然生态系统中发挥作用。简单地说，将透明管插入地面，并将具有100倍变焦的微型摄像机插入管中，并在现场的便携式笔记本电脑上捕获根部图像。每月或每周从试管中的同一位置收集根系图像，以确定哪些根已经生长，哪些根已经死亡，以估计地下生产力。这些根部图像在实验室中通过图像分析程序进行处理，该程序在图像中跟踪根部，然后计算生产率。该设备将帮助研究生调查细根在固碳中的作用，并增加我们对地下根系功能的理解。
