My exp. w/ NCDeptOfAg turnaround is good, however season dependant. If you send a sample off in the dead of winter, it will take up to six weeks to get it back. However, if you send one out during the months of May - October, the turn around is about 3 weeks. Nothing is fast, however, free is good.
I've sent approx 30 samples to them, of the same area... after soil additives, and am graphing the results on my Apple computer to show me what is needed next[if anything].
I have also found that if you send the sample directly to the lab in Raleigh, rather than depositing the thing at the local county Ag office, it will get done quicker.
I was wondering about the time of day as the photos seem to have borderline enough shade for 'sang in them [IMHO].
