Improved bioavailability of soil minerals and fertilizers

Stimulation of rooting

Increased access to mineral and water reserves

Increased Yield /quantity of fertilizer ratio


Produce maximum yield with the minimum of fertilizer

Improving the economic and environmental performance of fertilization means improving its efficiency, i.e. producing maximum yield with minimum fertilizing nutrients. To achieve this, it is essential to promote the soil microbial processes that influence the bioavailability of minerals to the plant.


Stimulate the functioning of rhizosphere microflora

Thanks to MIP® RHIZO technology, Primeo S12 provides soil microflora with the mineral elements essential to the functioning of enzymatic activities involved in the transformation of nitrogen and phosphorus forms. Primeo S12 improves
– mineralization of organic matter and nitrogen
– the nitrification process
– phosphatase activity
– the functioning of rhizosphere microflora

Technology: MIP® RHIZO
