Liventia Soil Pro is a liquid microbial biostimulant formulated with 5 high-concentration plant growth-promoting bacteria (PGPR) that enhances root development, boosts nutrient availability, and activates the plant's natural defense systems — including Induced Systemic Resistance (ISR) and Acquired Systemic Resistance (ASR) — to support stronger, healthier crops across a wide range of species.
Features & Benefits
High-concentration PGPR consortium: Powered by Pseudomonas fluorescens and Pseudomonas putida at 3.5 x 10⁸ CFU/ml each, with a total of 7.035 x 10⁸ CFU/ml — significantly higher CFU density than standard biostimulants.
Enhanced root growth: Promotes root development at key phenological stages including vegetative growth, flowering, fruit set, and fruit growth for stronger establishment throughout the season.
Activates natural plant immunity: Stimulates the PR1 gene, which governs the plant's defense response against pathogenic fungi and bacteria including crown gall — with documented results in walnut orchards.
Abiotic stress tolerance: Activates the PAL gene to induce tolerance against drought and extreme temperature fluctuations; antioxidant production is also promoted via GR1 and PhGPX gene expression.
Improves soil nutrition: Increases available nitrogen, phosphate, and potassium levels in treated soil while improving organic matter content and pH balance.
Broad crop compatibility: Labeled for use across 15 botanical families including Rosaceae, Solanaceae, Cucurbitaceae, Juglandaceae (walnuts), Vitaceae (grapes), and more.
Flexible application timing: Apply during root growth peaks, before anticipated stress events, or at each phenological transition — compatible with herbicides, insecticides, and water-soluble fertilizers when tank pH is 5.0–8.0.
OMRI listed: Approved for use in certified organic production.
Liquid formulation: Colorless liquid available in multiple sizes for small and large-scale operations.
