HUMIC AND FULVIC ACIDS

with acid pH

The humic and fulvic acids of Grabi Chemical are extracted directly from the best deposits of North Dakota in the US.

Leonardite is a concentrated fossil humus containing pure fossil humic acids formed by the natural humification in the course of several hundred millions years.

Humic and fulvic acids are exceptional in the agronomic branch because perfectly able to solve the problem of soil exploitation in modern intensive agriculture. The high quality content of both organic matter and organic carbon of biological origin make the product an effective soil conditioner.

SOIL

In soils poor in humus, soil particles are characterized by uncharged surfaces that cannot hold nutrients which consequently are lost in large amounts due to leaching.
Humic and Fulvic acids provide a ionic charge to the soil particles to retain nutrients hence preventing their losses.
Humic and Fulvic acids give the soil a negative charge (-), thus creating molecular attraction between the negative soil particle and the positive charge (+) of nutrients (fertilizer); opposites attract.
In this way nutrients are retained in the soil, promoting a food source for the newly forming root systems.

METABOLISM

Humic and Fulvic acids are able to activate the primary metabolism and the secondary metabolism in the plant.

The chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized

NITROGEN METABOLISM ACTIVATION

PHOTOSYNTHESIS ACTIVATION

Metabolic processes in which substances (such as pigments, alkaloids, or terpenes) are only synthesized in certain types of tissues or cells or are only synthesized under certain conditions. Not necessary for main cellular functions but they are useful to the plant as a whole
