PolarSprout® C5

Cold-Active Biological Support

PolarSprout® C5 is a biostimulating bacterial inoculant containing Bacillus atrophaeus strain ABi05, developed to support nutrient mobilization, plant resilience, and tolerance to abiotic stress across a wide range of agricultural systems. Suitable for soil, hydroponic, irrigation, and seed treatment applications, it supports plant establishment and crop vitality within integrated crop management programs. After application, beneficial bacterial spores colonize the root zone, supporting plant growth and resilience under variable conditions, including early-season stress. For best results, apply early in plant development, including seed treatment or at planting, under suitable soil moisture and temperatures above 47°F.

Supporting Plant Vitality and Early Development

Abiotic Stress and Early Crop Development

Early-season conditions such as low soil temperatures, limited moisture, and restricted nutrient availability can impact root development and overall crop establishment. These factors can reduce plant vigor and delay growth across a wide range of crops, including vegetables, fruit crops, ornamentals, and row crops. Environmental variability throughout the growing season can further influence plant performance and yield potential. Managing these conditions effectively is an important part of supporting consistent crop development.
