Phast Cal is a premium calcitic lime formulated to quickly raise soil pH in lawns and landscape beds where soil tests indicate acidic conditions.
Proper soil pH is essential for nutrient availability. When pH is too low, grass cannot efficiently absorb nitrogen, phosphorus, and potassium — even if those nutrients are present in the soil.
When to Use Phast Cal
- Soil test indicates pH below optimal range
- Lawn struggles despite proper fertilization
- Acidic soils common in your region
Always confirm pH levels with a soil test before applying lime.
Why Choose Fast-Acting Calcitic Lime?
- Raises soil pH more quickly than standard pelletized lime
- Calcium-based formula to improve soil balance
- Improves nutrient availability
- Supports stronger root development
Unlike dolomitic lime, calcitic lime focuses primarily on correcting calcium deficiencies and raising pH without significantly increasing magnesium levels.
Enhanced with Humic Acid & Sea Kelp
- 2% Humic acid to support soil structure and microbial activity
- 1% Sea kelp to assist nutrient uptake
These additions help improve overall soil health beyond simple pH correction.
Phast Cal provides a faster, more targeted approach to soil pH correction compared to standard pelletized lime products.

Applied as directed. Watering it
"Applied as directed. Watering it in to improve its effectiveness. Lawn is greener than it was before but it is still very much in early stage of going dormant while Spring like temperatures occur in the Fall."

Q&A
- Recent soil analysis of the yielded a pH reading of 5.89, which is moderately acidic, clay soil. What expectations should I have in the amount of PH to be raised when applied as instructed? Do I risk going to over the target PH level of 6 - 7? Or would I be better applying Dolomitic Lime?
- This is the recommended product for what you are trying to achieve. This product should be applied at 10 lbs. per 1000 sq. ft. to increase the soil PH by 1 point. You could apply the product 8lb. per 1000 if you wish to raise the PH less than 1 point. Dolomitic Lime will serve the same purpose, just over a longer period of time. It will also add magnesium to the soil for a magnesium deficiency as well.
- Is it for mostly lawns not food plots correct
- It can be used for either crop.
