Down To Earth™ Bio-Turf™ 8-3-5 Natural Granular Fertilizer — 4lb / OMRI Listed®

Down To Earth™ Bio-Turf™ 8-3-5 Natural Granular Fertilizer — 4lb / OMRI Listed®

Down To Earth™ Bio-Turf™ 8-3-5 is an entirely natural granular fertilizer formulated to build deep, resilient root systems while driving vigorous above-ground growth. With an 8-3-5 NPK profile, the nitrogen-rich formula delivers strong early season shoot growth and green foliage development, while the elevated potassium content supports stress tolerance during temperature swings, drought periods, and high-production demands — making it as valuable in vegetable garden beds and greenhouse growing operations as it is on lawns. OMRI Listed® for use in certified organic production programs.

Deep root development is the foundation of any productive growing program — plants with extensive, healthy root systems access more water and nutrients from the growing medium, recover more quickly from stress events, and sustain higher yields through the production cycle. Bio-Turf™'s naturally derived slow-release nitrogen fraction feeds soil biology gradually rather than overwhelming the root zone with a salt flush, supporting microbial activity that improves soil structure over successive applications. It is especially effective as a soil amendment for heavy-feeding vegetable crops like corn, tomatoes, and leafy greens that demand consistent nitrogen availability throughout their growth cycle.

Key Features & Benefits

• 8-3-5 NPK Profile — High-nitrogen formula drives strong vegetative growth; elevated potassium improves stress tolerance and supports high-demand production crops.
• Encourages Deep Root Development — Natural nitrogen sources support gradual nutrient release that stimulates extensive root growth, reducing irrigation requirements and improving drought resilience.
• Reduces Seasonal Stress — Potassium-fortified formula helps plants maintain osmotic balance and metabolic function during temperature fluctuations and water stress events.
• Natural Ingredients — Entirely natural granular composition supports soil biology and improves growing medium structure over repeated applications. OMRI Listed® for certified organic use.
• Versatile Application — Suitable for lawns, vegetable gardens, greenhouse growing beds, and container growing for heavy-feeding crops like corn, tomatoes, and leafy greens.

Who Should Use This

Greenhouse operators, market gardeners, and outdoor vegetable growers who need a reliable natural granular fertilizer that feeds plants consistently through the growing season without the salt loading of synthetic programs benefit from Bio-Turf™. It is particularly well suited to soil-based and amended growing media where natural nitrogen release and soil biology improvement are priorities alongside plant nutrition.

Compatibility

Apply as a top-dress or incorporate into growing media at planting. Natural granular — water in after application for nutrient release. Compatible with compost, biological inoculants, and other natural soil amendments. OMRI Listed® for certified organic production. Available in 4lb.

Frequently Asked Questions

Can Bio-Turf be used in container growing?

Yes — Bio-Turf™ can be incorporated into potting mixes or applied as a top-dress for container-grown vegetables and herbs. Use at the lower end of recommended rates in containers to avoid over-fertilization in the confined root zone.

How often should Bio-Turf be applied?

Application frequency depends on crop type and growing conditions. For most vegetable crops and lawns, monthly applications through the growing season maintain consistent nutrition. Follow the label rate recommendations for your specific crop and application method.

Is Bio-Turf safe for seedlings?

Use caution with seedlings — apply at reduced rates or wait until plants are established before applying granular fertilizers directly to the root zone to avoid fertilizer burn on tender seedling roots.

Can Bio-Turf be used with synthetic fertilizers?

Yes — Bio-Turf™ can be combined with synthetic fertilizers as part of an integrated nutrition program. Account for the nitrogen, phosphorus, and potassium contribution from Bio-Turf when calculating total nutrient inputs to avoid over-application.
