Sampling plant tissue and soil for analysis (1993)
(University of Missouri--Columbia. Extension Division, 1993)
Spectrographic analysis of plant tissue is a relatively new and accurate method for determining levels of major and minor elements in growing crops. However, good results make proper sampling of crops necessary. If you ...

Soil surface-seal measurement using high-resolution x-ray computed tomography (HRCT)
(University of Missouri--Columbia, 2006)
Rainfall on bare soil breaks soil aggregates, detaching particles, plugging pores and decreasing porosity in the top few mm of soil. This reduces hydraulic conductivity and increases runoff through a process known as surface ...
