OverGround ST XL Complex

Product with specific action on plants

OverGround ST XL Complex is an acqueous mixture composed of an inoculum of mycorrhizal fungi, rhizosphere bacteria, actinomycetes, yeasts and mineral extract-based mixture.

The micro-organisms establish with their roots a symbiotic and occupation of ecological niche relationship to foster a rebalancing in the organic soil activity. The active ingredients of the plant extracts at low concentrations stimulate the metabolism and regulate plant nutrition.

The complexity of the OverGround ST-XL Complex mixture, rich in many trace elements such as auxins, giberellins, polysaccharides, beta-glucans, trace elements and minerals, albeit at low concentrations, ensures full coverage of a plant's needs.

TIS (technology integrated system) applicata a OverGround ST-XL Complex regola le funzioni fisiche della pianta e quando si presentano alterazione nei campi elettromagnetici informazionali (CEI) ripristina le funzionalità cellulare portando in equilibrio il sistema biologico.


Physical state of the product


Product conservation

No specific conditions are required, but it is better if the product is protected from light. However, in order to achieve the best agronomic results, we recommend using OverGround ST-XL Complex within 8 months from date of production (see batch on the packaging).




The indicative quantities for each application are 15 l/ha, to which the irrigation water is added. Multiple applications are recommended, depending on the type of crop, and we suggest that you contact the technicians to get targeted protocols. OverGround ST-XL Complex poses no overdosing problems.

The product is spread via hose irrigation (drop by drop) or using a spray boom for sprinkling with nebulisers for the entire crop cycle. OverGround ST-XL Complex is used after completing irrigation with water only, as it allows a direct exchange with the roots.

A preharvest interval between the last application and consumption is not required.
