Usually i had extracted DNA from soil sample using power soil Qigen kit and got upto 700 ng/ul of DNA.
I do have a soil sample which has pH of 2.3 higlhiy acidic and one with 12.3 which is highly alkaline
i performed same extraction and got DNA only 3-5 ng/ul... that is not suitable for my downstream tests.
Can some one suggested what to do to increase yield of DNA from such sample.
