OverGround ST-Plus

Product with Specific Action on Plants

OverGround ST-Basic is a mixture composed of an inoculum of mycorrhizal fungi, rhizosphere bacteria, actinomycetes and yeasts able to establish a symbiotic and ecological occupancy relationship with the roots, thus fostering a microbiological rebalancing of the soil's organic activity in addition to plant extracts to help overcome transplant-induced stress and increase photosynthetic activity.

OverGround ST-Plus aids better root growth by stimulating the metabolic and photosynthetic activity to increase the plant's production levels.  

Physical State of the Product

The physical state is liquid.

Product Preservation

Specific conditions are not required, but it is best to store it away from the light. To get the best agronomic results from OverGround ST-Plus, it is recommended to use it within 8 months from the date of production (refer to the lot in the package).

The product is indicated in the pre-transplant phase (seedling bath in trays) and when planting by hose irrigation (drop by drop) or boom sprayer with sprinklers. OverGround ST-Plus is used after completing irrigation with water only. This provides a direct exchange with the roots.

No latency period between the last application and consumption is required.


The indicative quantities per operation are 2.5 l/100 l of water (seedling bath) and 15 l/ha at the time of planting. Several operations are required, depending on the type of crop. We recommend that you contact our technicians for targeted protocols. OverGround ST-Plus has no overdose problems.
