Elemental concentration changes in soil and stockpiled tall fescue leaves after liming
(University of Missouri--Columbia, 2006)Tall fescue (Festuca arundinacea Schreb.) is the dominant forage in Missouri and grows primarily on acidic soils that possess little plant available phosphorus (P). Little is known about the effects of lime on the elemental ... -
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 ... -
Use of slow-release N fertilizer to control nitrogen losses due to spatial and climatic differences in soil moisture conditions and drainage in claypan soils
(University of Missouri--Columbia, 2006)Agricultural soils are a major source of nitrous oxide (N₂O) which has a significant environmental impact on global warming and ozone depletion. However, there is little information on soil N₂O emissions under different ...
