My soil sample is of sandy loam.
I've done the extraction protocol several times, precisely as stated in the manufacturer's instruction manual but I did not get any good result. The concentration and purity of DNA extracted was very low when tested on NanoDrop specphotometer. I also have tried to reduce the volume of elution buffer (solution C6) but nothing has changed.
Any suggestion/recommendation for protocol modification from anyone who has experienced with this kit?
