Description
A proper soil is key to the good development of the crop. To supply all the shortcomings you may have, you can use Aptus Blast Humic. An organic fertilizer that stimulates the root system, microvide and improves soil structure in a general way, as well as water retention. Humic blast is responsible for neutralizing the accumulation of salts and acids in the middle.
Full description
Humic Blast by Aptus — Premium Humic Acids for More Active and Productive Substrates
Humic Blast from Aptus Plant Tech is the highest purity humic acid concentrate in the range, formulated to improve the structure of the substrate, enhance microbial activity and increase the availability of nutrients in the growing medium. Humic acids are the most complex and beneficial organic molecules for soil health.
Improves the structure of the substrate
Humic acids have a unique ability to improve the physical structure of the substrate. In soils and growing media, humic acids act as particle agglomerators, improving porosity, aeration and water retention capacity. A substrate with a better physical structure is more favorable for root development.
Increases cation exchange capacity
One of the most valuable properties of humic acids is their ability to increase the CEC (Cationic Exchange Capacity) of the substrate. A higher CEC means that the substrate can retain more nutrient ions and gradually release them to the roots, preventing deficiencies and optimizing fertilizer use.
Microbiota activator
The humic acids in Humic Blast stimulate the activity of beneficial microorganisms in the substrate, serving as a source of energy and carbon for the microbiota. A substrate with high microbial activity is more fertile and productive, capable of releasing and transforming more nutrients for plants.
Synergy with Fulvic Blast
Humic Blast works in perfect synergy with Fulvic Blast from Aptus. While Humic Blast improves the structure of the substrate and its retention capacity, Fulvic Blast transports nutrients directly to plant cells. Their combined use creates the most complete biostimulation program in the Aptus range. Consult the official table at aptus-holland.com.

Frequently asked questions
-
It is the purest humic acid concentrate in the Aptus range, formulated to improve substrate structure, boost microbial activity and increase nutrient availability. Humic acids are among the most beneficial organic molecules for soil health.
-
Humic acids act as particle binders, improving the porosity, aeration and water-holding capacity of the medium. A substrate with a better physical structure favours root development.
-
CEC is the cation exchange capacity of the substrate. Humic Blast increases it, so the medium holds more nutrient ions and releases them gradually to the roots, preventing deficiencies and optimising fertiliser use.
-
Yes, its humic acids act as a source of energy and carbon for the beneficial microorganisms in the substrate. A medium with high microbial activity is more fertile and productive, able to release and transform more nutrients for the plants.
-
With Fulvic Blast by Aptus: Humic Blast improves substrate structure and retention, while Fulvic Blast carries nutrients straight into the plant cells. Together they make up the most complete biostimulation programme in the range.
