Patrick Gann 585 Waughtown St. Jernigan Hugh 79-04 Rockingham 01/11/201301/04/201301/04/2013 Heavy Metals ATTENTION: 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: Lead (Pb) in sample 79041 is elevated signficantly. Although the above metals here are not believed to pose a concern for plant growth, continue to monitor these and note where elevated above background levels. This report was also flagged with a "C" and/or "Z" to alert you that copper and/or zinc have accumulated in the soil and are approaching a level that could be detrimental to crop production. The C and Z symbols are printed on your report for soil test index levels of 2000 or more; 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 biosolids 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. 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. Note any lime and fertilizer recommendations. Where soil test phosphorus (P) is very high (P-I > 100), crops will not respond to additional P applied. Tissue testing is advised where soil pH is elevated and where Zn and Cu levels are of concern as in samples found here.Jagathi Kamalakanthan 1/18/2013 Agronomist's Comments: Lime History: Sample ID: More Information Test Results [units - W/V in g/cm ; CEC and Na in meq/100 cm ; NO3-N in mg/dm ]: Soil Class: Ca%NO3-NSS-IESPNaCu-IZn-AIZn-IMn-AI2Mn-AI1Mn-IS-IMg%K-IP-IpHAcBS%CECW/VHM% 2 - 1 - Crop Recommendations:Lime BCuZnMnSMgK2OP2O5N Mineral Fes/OG/Tim,M 0.0 79041 120-200 0 $pH 000 0 322656.30.99211.80.860.60 22283144116569 0 70 Note: 12 112 1441 (tons/acre) 333 0 75 16 Nutrients (lb/acre) 0.2 0.2Selenium,6.7Lead,0.1Chromium,0.4Nickel,0.2Cadmium,0.2Arsenic,Heavy Metals (parts per million): Lime History: Sample ID: More Information Test Results [units - W/V in g/cm ; CEC and Na in meq/100 cm ; NO3-N in mg/dm ]: Soil Class: Ca%NO3-NSS-IESPNaCu-IZn-AIZn-IMn-AI2Mn-AI1Mn-IS-IMg%K-IP-IpHAcBS%CECW/VHM% 2 - 1 - Crop Recommendations:Lime BCuZnMnSMgK2OP2O5N Mineral Fes/OG/Tim,M 0.0 79042 120-200 Z $pH pH$00 0 483366.70.110028.10.660.46 13031325969130 0 40 Note: 12 Note: $ 48 3259 (tons/acre) 333 0 91 8 Nutrients (lb/acre) 0.3 0.0Selenium,5.8Lead,0.1Chromium,0.5Nickel,0.3Cadmium,0.2Arsenic,Heavy Metals (parts per million): - Steve Troxler, Commissioner of Agriculture Thank you for using agronomic services to manage nutrients and safeguard environmental quality. through a grant from the North Carolina Tobacco Trust Fund Commission.

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 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.
