Guaranteed analysis
Micronized calcium carbonate suspension, roughly 1.5 lb Ca per gallon.
What it does
Micronized calcium carbonate in suspension reaches a fraction of the particle size of ag lime, so it reacts fast and moves calcium onto the exchange instead of sitting on the surface for three years. The rate follows the formula: (target Ca percent minus current Ca percent) divided by CEC, times a CEC factor.
What it will not do
Skip it above 75 percent
If calcium base saturation already tests at or above 75 percent and pH is in range, we skip Pro-Cal and run the program without it. Buying calcium you do not need returns nothing.
Trial data and expected range
Micronized calcium-carbonate foliar restored photosynthesis and PSII efficiency under drought in controlled work.

- Expected range on row crops. Strip-trial it.
Tank-mix and handling
Calcium keeps its own pass. RED: never tank-mix with glyphosate (calcium ties up the glyphosate) or with high-salt phosphate loads like 3-18-18+ (they form a jelly). Stream or band on the row. Jar-test any new ratio.
Pro-Cal usually ships inside the hay and pasture foundation reset. Build the whole program off your soil test and see it in context.
