Our technology
The power of beneficial microorganisms
ALGOFERT-BIO® is based on consortia of plant growth-promoting rhizobacteria selected for their complementary functions.
Biostimulation
Vegetative and root development.
Biofertilization
Functions related to plant nutrition.
Biocontrol
Biological potential against selected harmful agents.
Native strains
Microorganisms originating from Algerian ecosystems.
From weakened soil to vigorous crops
A biological response developed for crops
The challenge
Soils and crops under stress
Declining biological fertility may restrict root development and agronomic performance.
The solution
Crops supported by PGPR
The consortia are developed to support beneficial interactions among roots, soil and microorganisms.
field measurement operations: stem height, spike length and recording of agronomic data.
Technology evaluated in the field
Trials conducted under real conditions
The formulations were evaluated on rainfed barley to study their effects on vegetative development and yield components.
- ✓ Rainfed crop
- ✓ Semi-arid conditions
- ✓ Non-inoculated control
- ✓ Agronomic measurements and statistical analyses

Experimental results
Performance observed in barley
The values shown represent the highest gains observed during comparative trials conducted with the ALGOFERT-BIO® consortia.
+357 %
Yield per spike
Highest gain observed with the R5 + RB4 consortium compared with the non-inoculated control.
+184 %
Grains per spike
Highest increase observed with the R5 + RB4 consortium under the trial conditions.
+61 %
Thousand-grain weight
Highest improvement in thousand-grain weight observed with the R5 + RB4 consortium.
Comparative analysis
Grains per spike and thousand-grain weight
Non-inoculated control compared with the three microbial consortia evaluated in the field.
The displayed results correspond to the experimental conditions of the trials conducted. They do not guarantee identical yields in every field or under all soil and climate conditions.
From laboratory to field
Prepared and evaluated formulations
The consortia were prepared, formulated on a solid carrier and then evaluated in ALGOFERT-BIO® experimental trials.
Culture and concentration of bacterial biomass
Incorporation into a sterilized solid carrier
Control of viability and microbiological purity
From research to product
