TMA - The Technology behind HERBAGREEN®

A number of minerals are and have been used in agriculture, especially Calcites and Zeolites, and various techniques have been tried to activate minerals to increase reactivity and capacity of these raw materials. TriboMechanical Activation (TMA) is a discovery made by Tihomir Lelas, a Croatian researcher and scientist. It is a new process of micronisation which enables production of submicron mineral particles and it involves a dynamic development of friction.



HERBAGREEN® micronised calcite particles are thus characterized by higher reactivity and a surface that is 300% more active than the mechanical processes used for milling. The concept of the product is entirely an innovative one: the TriboMechanical activation is the only technique through which such a particle distribution (0.1 to 40μ) is obtained with no metal residue present inside, and without the contribution of electrochemical techniques, which would otherwise spoil the natural composition of the mineral.


tehnologie-agricultura-3Once the HERBAGREEN®  powder is mixed with water and sprayed on a leaf surface, HERBAGREEN® starts working through directly penetrating the leaf pores (stomas – leaf organs which control the gas exchange in the plant) traveling through to the plants interior. This is possible due to the granulometry of HERBAGREEN® (0.1μm-40μm) which is much less than the size of a leaf’s pore opening (ostiole).
Due to the increased bioactivity in the leaf, the calcium and magnesium carbonates gradually disintegrate into oxides (CaO and MgO) and carbon dioxide (CO2). The carbon dioxide creates a leaf microclimate suitable for photosynthesis; it is used to create carbohydrates, and decreases the plant's need for water. Calcium, magnesium and iron increase the plant's resistance to disease (necrosis) and pests (downy mildew, gray mould, oidium), and promote chlorophyll creation. The silicon increases the plant's energy status, improves its growth and significantly shortens the time necessary for plant ripening. In other words, the treatment with HERBAGREEN® provides a micro-scale replication of the conditions that a leaf encounters in a greenhouse. HERBAGREEN® provides all the necessary nutrients for the plant by dissolving into CO and CaO, resulting in a permanent supply of CO inside the leaf making the plant almost self sustainable.
Common outcomes are less water consumption, vibrant colours, more fruit production, and stronger resistance to diseases and pests.


tehnologie-agricultura-4The mere presence of a particular chemical element in the soil does not guarantee the effective assimilation of mineral fertilizers by plants. Nutrient demand curves indicate stages in a plant's life-cycle when the need for some nutrients may be greater than the plant’s physiological capacity to supply itself, even when these soil nutrients are abundantly available.

Highly soluble potassium and nitrogen-based fertilizers can be easily washed out from the soil, and phosphate fertilizers can attach themselves to ions of potassium, magnesium, aluminum and iron into a chemically insoluble form for plants. Foliar nutrients on the other hand are mobilized directly into plant leaves, which are the goal of fertilization to begin with, increasing the rate of photosynthesis in the leaves, and by doing so stimulate nutrient absorption by plant roots.
By applying a foliar fertilizer directly to the leaf, it increases the activity in the leaf, at the same time increasing chlorophyll and thus photosynthesis. And by increasing photosynthesis, we increase production and efficiency. Excess carbohydrate produced by the plant, due to greater synthesis of sugars by the increased chlorophyll, are excreted by the root hairs.
