<br /> ( 'Total soluble ammonia/ammonium-N includes both soluble ammonia-N and ammonium-N in soil and was prepared by equilibration of soil aliquot with ASTM Type I deionized water.
<br /> ( bExchangeable ammonium analysis was prepared by extraction with 2N KCI.The extract was analyzed for ammonia and ammonium,which is the reported value,but ammonium would be the dominant form due to the pH of the extract.
<br /> `TKN+Nitrate(N)calculation only uses primary sample results and assumes a concentration of zero for U flagged results. Results rounded to whole numbers.

<br /> ( Notes:
<br /> Color coding:blue indicates a decrease of 50 percent from the concentration or 0.5 pH unit from the pH of the result from the previous data point.Red indicates an increase of 50 percent from the concentration or 0.5 pH unit from the pH of the result from the
<br /> 1 previous data point.Green indicates no significant change(plus or minus 50 percent or 0.5 pH unit)from the concentration or pH of the result from the previous data point.
