Nitrate in the Mississippi River Basin the previous day. An issue found with this is that the discharge changes day by day. This variation of discharge can increase the concentration one day, and the next day, there could be a decrease in it. This can make it problematic to observe the trends in the concentrations. Land use practices in the Mississippi River Basin have significantly decreased the amount of available nitrogen in the soil. This nitrogen is usually in the form of nitrate. The nitrate seeps through the soil and gets into the ground water through agricultral practices such as tile drainage, which eventually makes its
