Product description

BIO-PROTAN®N5 Vegetal is a liquid fertilizer made of organic acids and essential macro- and micro-elements resulting from the hydrolysis and fermentation of plant extracts.

The product contains many beneficial ingredients like amino acids, humic substances (humic and fulvic acid), betaine, vitamins, auxins and microelements. All this natural substances are right available for the plant, guaranteeing a high nutritional value and a plant-strengthening efficacy without leaching losses.

BIO-PROTAN®N5 Vegetal applied by foliar spray acts as bio-stimulant and supports plant recovery during climatic and biotic stress. The foliar application of exogenous amino acids (originating outside of the plant organism) helps the plant to save precious energy otherwise used for the synthesis and translocation of endogenous amino acids.

We also recommend the foliar use of BIO-PROTAN®N5 Vegetal for a successful and complementary support to the absorption of mineral fertilizers and nutrients naturally present in the soil.

The regular application of BIO-PROTAN®N5 Vegetal in fertigation favours microbial flora (Azotobacter / Pseudomonas) and improves the texture and structure of the soil. Increased fine root growth and a balanced crop development will raise the quality and quantity of your agricultural production. Betaine acid contained in the product is very helpful during drought periods for its function as organic osmolytes1.

BIO-PROTAN®N5 Vegetal is free from any chemical components that could be harmful to the soil and crops.

1 Osmolytes are substances synthesized or taken up by cells from the environment for the protection against stress situations (Osmotic stress, drought, high salinity or high temperature).
