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.

How long does it take to increase the soil’s ph?

pHast Cal includes bio-stimulants like Sea Kelp and Humic Acid for increased plant uptake of nutrients. The restorative effects of kelp on plants is largely due to high levels of cytokinin, a natural growth hormone that promotes cell division in plants, resulting in root and shoot growth, improved photosynthesis and overall improvement in plant health. All natural bio additives increase the population of soil microbes, which increase nutrient efficiency and build healthier soils that store nutrients for the plant.

What’s the difference between regular lime and pHast Cal Lime?

Regular lime is dolomitic limestone which is still good but it will take 10x more and it will work much slower. pHast Cal lime contains calicatic lime which works much faster and is 10x more concentrated. Also pHast Cal contains Kelp and Humics which increases plant uptake of nutrients.

Should I perform a soil test before applying pHast Cal Lime?

You should perform a soil test to see if your ph needs to be increased. If so, follow the application rate instructions to increase ph. However, pHast Cal is great for just a maintenance application once a year.

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.
