0236750SchaapThis grant will support the costs of developing a Feedback Syringe Pump Method (FSPM) for the rapid, precise, and direct determination of unsaturated hydraulic conductivity (K) and water retention in soil samples. The system will be fully automated and will require minimal operator attention. Phased developments will include: 1) construction of a prototype system to optimize and test various system components and control methods, and 2) development of a system for routine measurements that would accommodate six to eight samples at a time. These activities will involve collaboration between the University of California at Riverside and the George E. Brown Jr. Salinity Laboratory (USDA-ARS) in Riverside. Funds will purchase materials necessary for development of the FSPM and will support part of the salary for the PI and a postdoc. No NSF funding is requested for the activities of the collaborator or the GEBJ Salinity Laboratory.***

0236750 Schaap该赠款将支持开发反馈注射泵方法（FSPM）的费用，用于快速，精确和直接测定土壤样品中的非饱和导水率（K）和持水性。 该系统将是全自动的，将需要最少的操作员注意。 分阶段的发展将包括：1）构建原型系统，以优化和测试各种系统组件和控制方法，以及2）开发一个用于常规测量的系统，该系统一次可容纳6至8个样品。 这些活动将涉及加州大学滨江分校和乔治大学之间的合作。布朗一行滨江的盐度实验室（USDA-ARS）。 资金将用于购买开发FSPM所需的材料，并将支持PI和博士后的部分工资。合作者或GEBJ盐度实验室的活动不需要NSF资助。
