ATTENTION: This report was 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 Zn and Cu index levels of 2000 or more for agronomic crops; for peanuts with
zinc, the level is 250. 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 and Zn is set at a 3000 index; for peanuts with zinc, the level is 500. Maintaining a pH of 6.0 or higher may reduce
potential for toxicity, especially for Zn. 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. 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 lead (Pb) in both the samples. 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.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 test is suggested where soil zinc(Zn) and or copper ( Cu) levels are elevated and are of
concern as in samples found here. Jagathi Kamalakanthan 12/2/2019

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
.
