Fig. 4. Examples of observed and scored indicator results, illustrating the four general relationships that occurred: (a) observed and scored results were equivalent (example is potentially mineralizable N from Natural Resource Inventory [NRI] cropped Xerolls data), (b) observed and scored results were opposite (example is soil test P from GA data), (c) observed results had significant differences but scored results did not (example is sodium adsorption ratio [SAR] from California data (org = organic; low = low input; conv 4 = 4-yr conventional rotation; conv 2 = 2-yr conventional rotation), and (d) observed results showed no significant differences among treatments but scored results were significantly different (example is soil pH from IA data). Treatments labeled with different letters are significantly different at 
= 0.05. Error bars represent one standard deviation from the mean. WS represents watershed.
