I submitted my 12 samples to NC agronomic services this morning. Right now their turnaround is one-week. Though in conversation with the folks this morning, they expect the turnaround times to increasing significantly over the next few weeks as those who start their renovations around Labor Day submit theirs. So heads up for those who get their's tested. I don't renovate my yard until late September hoping to avoid the one last heat wave and the historical hurricane washout. But I'd rather have my results waiting on me than me waiting on the test results.
