- What is the concentration of ions in the soil solution after fertilizer application? Suppose that 122 pounds of K+ were applied per acre, then a gentle rain soaked the top 10 inches of soil to field capacity, which for the given soil was about 16% water by volume. If the K+ was applied as KCl, it is plausible that it all dissolved and distributed relatively uniformly with the infiltrating water. If so, then what was the K+ concentration in the soil solution in mol K+/L solution? Note that the volume can be computed like we do for an acre-furrow-slice (AFS), as area times depth. This is going to be a relatively small number, so please report your answer in mol K+/L solution to at least 5 decimal places.idea how gravimetric analysis provides accurate results despite of it being time consumingBackground info: The cyanobacterium Arthrospira platensis, colloquially known as Spirulina is/was a popular health food/supplement because it is extremely rich in amino acids and vitamins. However, these cyanobacteria also happen to be extremely good at absorbing lead, which means that these supplements are often contaminated with toxic amounts of heavy metals. One suggested application for these cyanobacteria is in bioremediation systems for industrial/mining wastewater contaminated with lead. Question: What is the difference between remediating toxic elements like lead versus toxic organic compounds like TCDD?
