Wilmington, NC 28405 Linda Melville 2032 Belgrade-Swansboro Rd. Maysville, NC 28555 Sampled County : Onslow 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 to extremely elevated zinc (Zn) in all the samples and elevated copper (Cu) in samples 00001 and 00002. 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 pH is elevated and where Zn and Cu levels are of concern as in samples found here; additionally Mn concern was also noted. Note any lime or fertilizer recommendations especially for Mn as small grains are sensitive to Mn deficiency.

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.
