Humic Acids  


HUMINTECH products are used in organic horticulture, especially in greenhouses.  

Crop production, e.g. in greenhouses, involves the creation of favorable microclimates, where cultivation is possible throughout the year or part of the year as required in order to obtain high yield and good quality in short time.

Not only the optimization and regulation of environmental parameters traditionally used, such as temperature, light, carbon dioxide, relative humidity, are important, but also the creation of a desirable growing medium (soil or substrate) which provides appropriate physical, chemical and biochemical properties.

The application of humic acid based products helps to prepare a desirable growing medium by providing good porosity, by increasing cation exchange capacity (CEC) and by improving biological activity. As a result, growing medium is well aerated, roots can penetrate more easily, nutrients and water are better stored, pH is buffered against extreme ranges and salinity is reduced. For instance, if the root system is well developed, not only the nutrient uptake capability of plants is improved, but also their resistance against diseases.

Humic acid based products of HUMINTECH, due to their excellent properties, provide the benefits mentioned above, to stimulate plant growth and thus obtain high yield and an adequate quality in all horticultural crops.


Increased growth of tomato plants after PERLHUMUS® application (Turkey)

PERLHUMUS® was blended with the soil substrate before planting of tomato cultures. Plants treated with PERLHUMUS® show an increased growth and a strengthened shape. (pic. 1, fig. 1)

The growth of the plants increased by about 15 percent after application of 25 l/ha LIQHUMUS®.  (pic. 2)

General Benefits of HUMINTECH Products 

Quantitative and qualitative yield increases

Regular application of high quality humic acids accumulates their effects in soils and continuously enhance the quantitative and qualitative yields. The dry matter of the plants is increased, which also positively affects the taste of fruits and vegetables. In addition, the quality of the fruits and their shelf life is extended. Our results from practice in different countries show the yield increase in different cultures.

Reduction of water demand 

The accumulation of organic matter by humic acids binds the seeping water especially in sandy soils. Thereby the water demand can be reduced by up to 50 percent depending on the soil type. Thus, precious water is saved in arid areas. 

Increase of the nutrients' efficiency

The addition of humic acids increase the fertilizer efficiency and the nutrient uptake by roots. Thus they can decrease the need of fertilizers up to 30 percent and reduce the production costs substantially. The reduction of fertilizer saves the environment at the same time.


The profit from increased yields, improved fruit and vegetable qualities, and saved fertilizer costs definitely exceeds the application costs of HUMINTECH products. You can benefit economically and ecologically from the application of humic acid based products in the long term. They are a guarantee for successful yields in any kind of soil, at any place and with any cultivation method.
