Dope! I will post a mix Worthy of this continuation during the coming outdoor season.
Before we go any further-
Soil Math and Glossary 101
TEC - Total Exchange Capacity - Of all particles and receptor sites in a mix, a value which demonstrates the size and ability to retain or make available cations and anions.
Cations - Elements or ions, of which the net result is a positive charge.
Anions - Elements or ions, of which the net result is a negative charge.
CEC - Cation Exchange Capacity - "The total capacity of a soil to hold exchangeable cations. It influences the soil's ability to hold onto essential nutrients and provides a buffer against soil acidification."
EC - Electrical Conductivity (measured in micro-siemens, µS/cm, "measure of the concentration of dissolved solids which have been ionized in a polar solution *cough* water")
ppm/ppb - Parts per million/billion
mEq - milli-equivalents/(typically of 100 grams of soil or mix content)
Bulk Density = mass of dried soil per volume of that soil when field ready (dry weight of the soil and divide by total volume). Usually expressed in grams per cubic centimeter. - biggreg
Percent Nutrient Saturation - Each elements individual presence in the TEC
Percent Base Saturation - The sum of a groups (Ca ++, Mg ++, K+, Na+, H+, [sometimes Fe ++, Zn ++, Cu ++, Mn++, Al +++]) percentage or presence as cation's
in the TEC
M3 - Melich 3 testing method- an extractant which when combined with soil samples will separate elements from each other and organic material to determine nutrient saturation.
AA @ 8.2 - Ammonium Acetate/pH 8.2 testing method -an extractant used to determine nutrient saturation which does not overestimate Ca++ content, which M3 may.
Calculating Base Saturation
