This report contains both routine soil test information as well as heavy metals data in a section labeled as Heavy Metals under soil test lab results. Using Mehlich 3 as a soil test
extractant, background levels of these metals typically seen in NC soils when analyzed are as follows: arsenic (As)- 4.5 ppm, cadmium (Cd)- 0.1 ppm, chromium (Cr)- 0.2 ppm, lead
(Pb)- 4.2 ppm, nickel (Ni)- 0.8 ppm, & selenium (Se)- 0.2 ppm (FY2005-2007). Note elevated zinc(Zn), copper (Cu) and lead (Pb) in the sample. Soil test index levels for Cu and Zn of
2000 are levels of potential concern where any waste applied containing the metals should be discontinued; for peanuts with zinc, the level is 300. This note is designed to be a "trigger"
that allows enough time to either reduce the rate of application or find another field for application of bio solids and/or waste water. The CTL (critical toxic level) for Cu & Zn has been
set at 3000 index; for peanuts with zinc, the level is 500. Maintaining a proper pH, usually of 6.0 or above, is critical in management to reduce the risk of metal toxicity. These levels are
used by DENR as a benchmark to determine when application of waste products should be stopped. The CTL for copper and zinc was set to prevent levels from accumulating to the
point where they become toxic to crops grown on a field. Where soil test phosphorus (P) is very high (P-I > 100), crops will not respond to additional P applied. Tissue testing is
advised where Zn and Cu levels are of concern as in samples found here. Note any lime or fertilizer recommendations. Jagathi Kamalakanthan 1/7/2015

Recommendations
Lime
If testing finds that soil pH is too low for the crop(s) indicated, a lime recommendation will be given in units of either
ton/acre or lb/1000 sq ft. For best results, mix the lime into the top 6 to 8 inches of soil several months before planting.
For no-till or established plantings where this is not possible, apply no more than 1 to 1.5 ton/acre (50 lb/1000 sq ft) at
one time, even if the report recommends more. You can apply the rest in similar increments every six months until the
full rate is applied. If MG is recommended and lime is needed, use dolomitric lime.
Fertilizer
Recommendations for field crops or other large areas are listed separately for each nutrient to be added (in units of
lb/acre unless otherwise specified). Recommendations for N (and sometimes for B) are based on research/field studies
for the crop being grown, not on soil test results. K-I and P-I values are based on test results and should be > 50. If they
are not, follow the fertilizer recommendations given. If Mg is needed and no lime is recommended, 0-0-22 (11.5% Mg) is
an excellent source; 175 to 250 lb per acre alone or in a fertilizer blend will usually satisfy crop needs, SS-I levels appear
only on reports for greenhouse soil or problem samples.
Farmers and other commercial producers should pay special attention to micronutrient levels. If $, pH$, $pH, C or Z
notations appear on the soil report, refer to . In general, homeowners do not
need to be concerned about micronutrients. Various crop notes also address lime fertilizer needs; visit
Recommendations for small areas, such as home lawns/gardens, are listed in units of lb/1000 sq ft . If you cannot
find the exact fertilizer grade recommended on the report, visit to find
information that may help you choose a comparable alternate. For more information, read

Test Results
The first seven values [soil class, HM%, W/V, CEC, BS%, Ac and pH] describe the soil and its degree of acidity. The
remaining 16 [P-I, K-I, Ca%, Mg%, Mn-I, Mn-AI1, Mn-AI2, Zn-I, Zn-AI, Cu-I, S-I, SS-I, Na, ESP, SS-I, NO3-N (not
routinely available)] indicate levels of plant nutrients or other fertility measurement. Visit
