Early-Season Advantage and Soil Activation for Stronger, Higher-Yielding Crops
IgniteS2®: Better Uptake. Better Crops.
IgniteS2® is AgriGro®’s early season biological soil and plant stimulant designed to give crops a stronger, more uniform start when conditions are most limiting. It is built for in furrow and 2x2 starter applications, and it also fits easily into herbicide passes, fertigation, and broadcast soil programs. IgniteS2® is not meant to replace your fertility plan, it is designed to make that plan work better by activating biology in the root zone and improving nutrient availability when the crop needs it most.
Where many starter approaches focus only on N P K, IgniteS2® is positioned as a biological performance tool that helps crops push through early season stress such as cold soils, residue pressure, uneven emergence, and limited nutrient access. The result is better early development, improved fertilizer efficiency, healthier plants, and more consistent yield potential across the field.
Accelerated Residue Breakdown
Speeds the decomposition of crop residue to promote faster nutrient cycling
Improved Nutrient Availability
Helps release nutrients tied up in plant residue for use by the following crop
Enhanced Soil Biology Activity
Stimulates native microbial activity responsible for residue decomposition
Improved Soil Structure
Supports better soil aggregation, airflow, and water movement as residue breaks down
Cleaner, More Manageable Seedbeds
Reduces surface residue to improve planting conditions and early root development
Supports Early-Season Crop Vigor
Creates a more biologically active soil environment for faster, more uniform emergence
Root Zone Activation That Supports Emergence and Early Growth
After application, IgniteS2® stimulates native microbial populations in the root zone and supports increased production of root exudates. That combination drives stronger biological activity and improved enzymatic function in the rhizosphere. As soil biology becomes more active, nutrients that are commonly tied up become more available, and the crop is better positioned to access both applied and residual fertility.

Application Rates
In-Furrow Application
Apply 16 oz per acre in-furrow at planting to support early root development and nutrient availability.
Soil-Applied / Broadcast
Apply 16–32 oz per acre as a broadcast soil application using standard ground, aerial, irrigation, or fertigation equipment.
Where It Fits
IgniteS2® works in in-furrow, 2×2 starter, broadcast soil programs, herbicide passes, and fertigation systems, offering flexibility across application windows.
Tank Mix Compatibility
IgniteS2® is compatible with most herbicides, pesticides, fungicides, and liquid fertilizers.
