Already presented a study that is potentially relevant in any managed system, including turf grass. How about you read it and the ~ 170 citations before you post again. Furthermore I never said it wouldn't lead to an increase in SOC as you are inferring ..... I said you can't assume it will lead to an increase as you stated. Why exactly is it so hard for you to admit the possibility exists, especially given the study I linked? With all your "experience", why haven't you learned to not speak in absolutes when discussing biological systems?

Can you point me to a turf grass research project with same time range of data as the Morrow plots?

Still waiting on those scientifically rigorous studies you performed that validates this and your claim that a top dressed OM + synthetic N will (always) lead to an increase in SOC, per your continued argument here.

Hmmmm, all because I understand that A + B does not necessarily lead to C.

OK Quack, I guess we are done here.

OH and BTW Bill and Barry .... take note of your boy and his forum etiquette.
