OverGround ST-Starter

Product with Specific Action on Plants

OverGround ST-Starter 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.

  By virtue of the select "biostimulant" ingredients, OverGround ST-Starter fosters the assimilation of phosphorus, stimulates initiation of the plant's vegetative-productive activity and improves its growth phase.

Physical State of the Product

The physical state is liquid.
