Calcium is so available in most soils and so expensive to put in a Fertilizer Blend that most Manufacture don't add it in their Blends. Calcium Nitrate is most common source of Calcium and is normally applied by spray. It will give great strength to turf that is other wise weak and won't stand up. Golf Greens will use Calcium Nitrate to increase the speed of the ball rolling across the green because the turf stands up and doesn't bend from the ball.

Other sources of Calcium are. Calcium Ammonium Nitrate, Calcium Cyanamide and Single and Triple Super Phosphates.

The Only compound of Potassium that has Magnesium is Potassium Magnesium sulfate. All the others list here don't have Magnesium. Potassium Chloride which is the most common used in Cheap blends of fertilizer, Potassium Nitrate, Potassium thoisulfate, And the Best Potassium that you should use is SOP Sulfate of Potash or Potassium Sulfate.

I am not sure where you are coming from but I hope this answers your question.

I've used the Solu-Cal gypsum product. It did a very nice job.

Most all beetles like to lay their eggs in organic material of any kind. That doesn't mean they won't lay them else where. In the case of Mask Chafers they love to eat the roots of St Augustine grass and lay their eggs just above the high water mark so they get the same high moisture that Organic material will hold.
