Calcium, as an essential plant nutrient in the soil, is often overlooked. Too many times when soil tests show a low pH the immediate reaction is to spread more lime. However, ag-lime tends to be insoluble and can take years to break down and show its effectiveness. In fact, the odds are good that your soil may already contain more undissolved limestone than soil tests are calling for.
Rather than just looking at soil pH, an effective soil test should also include the quantity of soluble calcium (measured in ppm or %) and the calcium % base saturation in the soil. pH alone is not a valid indicator of soluble calcium levels in the soil. For example, when pure sand is analyzed it has a neutral pH but has no available calcium.

Directions For Use
When should I apply AgriCal®?
There is no wrong time to apply AgriCal® if calcium is indicated by your soil test or tissue analysis. The sooner the better.
Can I mix AgriCal® with my starter fertilizer?
Absolutely not if your starter contains phosphorous, which almost all do. It would require an independent tank with a separate line ran to the seed furrow. AgriCal® can be mixed with any of our prebiotics in furrow.
Can I raise my pH with AgriCal®?
It is possible depending on the history of your soil, but that is not the intended purpose nor the guide to determine the need or the rates of application for using AgriCal®. A low pH can be an indicator calcium is deficient but the pH can also be above 8 and calcium can still be deficient. Do not use pH as a blanket indicator for applying any nutrient to the soil including lime or AgriCal®. The results can be a very costly unbalanced soil.
