Default fertilizer

Ron,

Could you please explain the relationship between a fertilizer which has N-P-K expressed in percent (ex. 10-10-10) and PPM,can the pecentage be converted to PPM.

Further is the correct conversion from milliSiemens(mMhos/cm) to PPM. 1 PPM = 6.5 mMhos.

Thanks for your time

Rick
