Soil Test Interpretation for Peonies
Directions: This interactive calculator is intended as an exploratory tool to help you interpret your soil test results for a single soil sample. Calculations are based on a generalized model of soil variable for Alaska soils. The yellow highlighted boxes labeled "Enter Your Values Here" are available for you to enter information. This calculator will only make calculations for the data you have entered. You will need to double click in the box to activate the spreadsheet so that you can enter data. There are many variables listed that you may enter. Depending on the soil test you have obtained, you may not have data to enter in every box. To start over and enter information from a different soil test, click the refresh button of your browser. If you are having difficulty with this calculator and would rather seek assistance directly from an extension agent .
INTERPRETATION OF RELATIVE SOIL FERTILITY LEVELS
LOW - A nutrient or other component interpreted as "low" will likely limit plant growth and yield. There is a high probability of improved yield from an addition and/or higher level of this component. If the level is very low, several years of corrective fertilizing may be necessary to achieve an optimum soil level. In this case, close monitoring by yearly soil testing is recommended.
MODERATE - A nutrient or other component interpreted as "moderate" has a moderate probability of an improved yield from an addition and/or higher level of this component. A moderate nutrient level may limit plant growth or yield by the end of the growing season or in years of very good growing conditions, but it may be adequate for some low-demand crops in some cases. Corrective fertilizing is usually recommended in moderate amounts to result in a slight increases in soil levels and yield in years of average growing conditions or to support exceptional yield during years of excellent growing conditions.
OPTIMUM - A soil component listed as "optimum" is in the theoretical ideal range to support plant growth and maximum yield. There is a low probability of an improved yield from a higher level of this component. Corrective fertilizing is not recommended. Any amendments recommended for components listed as "optimum" are to compensate for crop removal, so that the soil level of nutrients can be maintained from year to year. A small amount of starter fertilizer containing this nutrient may also be recommended.
ABOVE OPTIMUM - An "above optimum" level of soil component indicates a level higher than needed
