AgriPept SoilPlex – PGA-Based Biotechnology for Soil Vitality and Nutrient Recycling

Overview – A Living System for Soil Fertility

AgriPept SoilPlex is an innovative microbiological product that accelerates straw decomposition, improves nutrient release, and rebuilds the natural balance of the soil ecosystem.

Developed by PeptechLab, the formulation combines γ-polyglutamic acid (PGA), living bacterial strains (10⁸–10¹⁰ CFU/ml), and metabolic bioactive compounds.

This synergy enhances mineralization, humification, and microbial activity, making SoilPlex a key tool for regenerating soil health and increasing yields sustainably.

Based on recent studies, SoilPlex optimizes the decomposition of organic residues and improves the release of nitrogen, phosphorus, and potassium (NPK) by 20–25%, reducing fertilizer costs and boosting nutrient bioavailability throughout the growing season.

Mechanism of Action – From Decomposition to Regeneration

The high content of γ-polyglutamic acid (12–20%) acts as a biohydrogel and chelating biopolymer, improving soil moisture retention and cation exchange capacity (CEC).

PGA creates a microenvironment that supports enzymatic activity and the aggregation of beneficial microorganisms, even under drought or salinity stress.

This biofilm-like network enhances oxygen exchange, stabilizes microbial communities, and accelerates enzymatic decomposition of cellulose and lignin.

During humification, PGA stimulates the formation of stable humic substances and carbon sequestration, increasing the humification index.

By activating microbial respiration, SoilPlex increases oxygen consumption rates and microbial biomass, turning inactive soil into a biologically vibrant system.

Biological and Chemical Impact

SoilPlex works as a natural carrier of macro- and microelements, enhancing the solubility and mobility of P, K, Mg, Fe, and Zn for plant uptake.

The microbial consortium and PGA also support the bioremediation of pesticide residues and excess nitrates, limiting pathogen development and improving the soil’s biochemical balance.

AI-assisted bacterial strain selection ensures consistent efficiency across soil types and climates, while PeptechLab’s precision fermentation guarantees record-high active compound concentrations.
