The fertilizer stabilizer

Did you know you can reduce nitrogen applications by 30% or more by using HumaCarb

HumaCarb is a natural concentrate of humic substances derived from humalite deposits,

designed to enhance nutrient absorption and reduce the need for fertilizer applications. 



• Holds nitrogen and phosphorus in the root zone*

• Aids in the uptake of micronutrients**

• Chelates plant nutrients***

• Optimizes soil conditions for better overall plant mass****


How does HumaCarbwork?


Humic substances have a high anion exchange capacity which allows them to hold nutrients such as nitrogen and phosphorus in the soil, preventing them from leaching. 


Unlike other humic acids available on the market, HumaCarb is produced using a process that preserves all the natural properties of the humic substances so you get 100% benefit from the 100% all-natural, naturally-mined Humalite.

Why should I apply HumaCarb?

Traditional soluble salt fertilizers are unstable and can be leached out of the root zone or become complexed by soil minerals very quickly. Stable humic substances such as those found in HumaCarb are proven to hold nutrients in the root zone longer and reduce potential fertilizer loss, as well as significantly enhance soil microbiology. That means more savings for you, and healthier soil!

More about HumaCarb

How can HumaCarb be applied?

  • HumaCarb should be tank mixed with liquid fertilizers as 3% of the total solution. 

  • HumaCarb may be mixed with liquid manure to stabilize nitrogen and reduce odor while softening the harsh effects of applying raw manure.

  • Typical application rates are 2-3 quarts per acre.

While this product can be used individually, it is intended to be used along with other complementary products as part of an overall fertility program designed to produce the highest quality results.

Our consultants work with large growers to create customized crop programs, combining our biological and mineral nutrition products with regenerative practices to improve crop quality, yields, and disease and insect resistance while regenerating soil health.


* Depending on the form of fertilizer applied, nitrogen may become a structural component of humic substances as a stable organic material, preventing it from leaching through the soil. (Haworth, 1971; Stevenson, 1982; Haynes and Swift, 1990; Kelly and Stevenson, 1996) In their natural state, humic substances contain anywhere from 1% to 5% nitrogen. Reduction of nitrogen application (Day, et al, 2000, Fataltah, et al, 2001).

** The stimulatory effects of the humic substances have been directly correlated with enhanced uptake of macronutrients, such as nitrogen, phosphorus, sulfur (Chen and Avia, 1990) and micronutrients i.e. Fe, An, Cu, and Mn. (Chen et al, 1999).

*** Chelation and complexation by humic substances keeps plant nutrients in soil solutions (Tan, 1986, Chen et al, 1999, Clapp, et al 1998).

**** The stimulatory effects of humic substances have been conducted by the USDA-ARS soil lab in Minneapolis (Clapp et al, 2001; Chen et al, 2001; Chen et al, 1999, Chen et al, 2004) and worldwide (Karr, 2001).
