PROVEO star

Technological profile of PROVEO star: a microelement matrix

The mineral fertilizer PROVEO star by the Slovakian manufacturer Envivia, s.r.o. is a concentrated liquid solution designed for precise correction of nutritional deficiencies during critical growth stages. Unlike simple mono-fertilizers, this preparation shifts plants into an active metabolic state through the synergy of an N-P base (1-5% of each element) and a deep microelement complex.

Chemical architecture and bioavailability

The core value of the formulation lies in the balanced combination of chelated microelements. In field conditions, this addresses the issue of "hidden hunger" in intensive crop rotations (rapeseed, corn, cereals):

• Iron (Fe) and Manganese (Mn): Ensure photosynthetic stability, preventing chlorosis in carbonate soils.
• Boron (B) and Molybdenum (Mo): Crucial for the formation of reproductive organs, pollination, and nitrogen fixation in soybeans and sunflowers.
• Nickel (Ni): Micro-doses of this element assist in urea metabolism, enhancing nitrogen uptake efficiency during foliar applications.
• Sulfur (S): Integrated into amino acid structures, it directly impacts harvest quality (grain protein content, oil content).

Why is the liquid form important?

The product is supplied as a highly stable solution, ensuring the uniformity of tank mixtures during preparation. Upon foliar application, the molecular structure of PROVEO star facilitates rapid penetration of active ingredients through the leaf cuticle. This allows the plant to achieve a "fast start" without the stress period typically associated with granular fertilizers that require time to dissolve and be assimilated.

Application guidelines

With a hazard class of 4, the product is safe for handling and environmentally friendly. The recommended strategy is foliar feeding during periods of peak crop demand: from the tillering stage in cereals to the head-forming stage in sunflowers or pod development in rapeseed. Using PROVEO star allows agronomists to mitigate risks associated with sudden temperature fluctuations and moisture stress, when the root system temporarily reduces its nutrient uptake activity from the soil.
