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 revent levels from accumulating to the point where they become toxic to crops grown on a field.

For best results, mix the lime into the top 6 to 8 inches of soil several months before planting. BS% % CEC occupied by basic cations For no -till or established plantings where this is not possible, apply no more than 1 to 1.5 ton/acre (50 Ib/1000 sq ft) at on Ca% % CEC occupied by calcium time, even if the report recommends more. You can apply the rest in similar increments every six months until the full rate CEC cation exchange capacity is applied. If MG is recommended and lime is needed, use dolomitric lime. Cu-I copper index ESP exchangeable sodium percent Fertilizer HM% percent humic matter Recommendations for field crops or other large areas are listed separately for each nutrient to be added (in units of K-I potassium index lb/acre unless otherwise specified). Recommendations for N (and sometimes for B) are based on research/field studies K20 potash for the crop being grown, not on soil test results. K-1 and P-1 values are based on test results and should be > 50. If they Mg% % CEC occupied by magnesium are not, follow the fertilizer recommendations given. If Mg is needed and no lime is recommended, 0-0-22 (11.5% Mg) is MIN mineral soil class an excellent source; 175 to 250 lb per acre alone or in a fertilizer blend will usually satisfy crop needs, SS-1 levels appear Mn manganese only on reports for greenhouse soil or problem samples.
