Can Infrared Spectroscopy Be Used to Measure Change in Potassium Nitrate Concentration as a Proxy for Soil Particle Movement?
Displacement of soil particles caused by erosion influences soil condition and fertility. To date, the cesium 137 isotope ((137)Cs) technique is most commonly used for soil particle tracing. However when large areas are considered, the expensive soil sampling and analysis present an obstacle. Infrared spectral measurements would provide a solution, however the small concentrations of the isotop...

متن کاملNitrate interference with potassium-selective microelectrodes
tions of K+, and triple-barrelled microelectrodes measuring K pH and membrane potential m have provided Initial attempts to measure K+ activity (a K ) in vacuoles a major advance towards this goal ( Walker et al., 1995, of barley leaf epidermal cells using triple-barrelled K+1996). The incorporation of a pH-sensing barrel allows selective microelectrodes gave values that were only unequivocal a...
متن کاملStudy of nitrate rate in some vegetables cultivated in Poldokhtar and Khorramabad, Lorestan province
Background and Objective: Nitrate is one of the most important factors in determining the quality of vegetables. Today, due to the excessive use of nitrogen fertilizers to accelerate vegetative growth, many vegetables have a high percentage of nitrates in human diet. The purpose of this study was to investigate the concentration of nitrate in four vegetable species cultivated in Poldokhtar and ...
