BOLSTER GRANULAR 4-4-4 + Iron

25 years of applied research have consistently proven Suståne Natural Fertilizers to be the leader in plant establishment, soil physical improvement, and biological disease suppression. Suståne Triple Four is made from a thorough, aerobic composting process unlike any other organic fertilizer on the world market today. This basic Suståne contains 3% organically chelated iron plus all major and minor elements known to be essential for plant photosynthesis. This is an 80% Slow Release Nitrogen ratio natural fertilizer rich in humic substances, is foolproof, and will not cause “fertilizer burn” to plant materials. To improve on Basic Suståne’s unsurpassed plant establishment, the following components have been added:

VA mycorrhizae

Vesicular Arbuscular Mycorrhizal Fungi: Glomus intraradices, Glomus etunicatum, Glomus deserticola, and Glomus clarum. Guaranteed a minimum of 3.52 propagules per g. Mycorrhizal presence equates to “Healthy Soils”. It affects available soil nutrition, the physical structure of the soil, and the number of and types of other organisms present in the soil. “Mycorrhizae” refers to the species of fungi that form beneficial associations with plants. It is a “Facilitator” that brings nutrients to plant roots, exudes “Glomalin” to improve soil structure, and actually fill up available entry sites along roots to inhibit pathogens from attacking. Mycorrhizal fungi are a critical component of healthy soils.

Enhanced mycorrhizal inoculant with beneficial microbes and humic acid

For Superior Nutrient Uptake and Growth Promotion

Bolster^® MycoBio™ from Sustane^® is a blend of endo mycorrhizae species and beneficial bacteria, with humic acid and compost to support the proliferation of soil microorganisms.  Bolster MycoBio is used for inoculating soils and growing media with beneficial microbiology for improved nutrient cycling and to amend soil to improve seedling success and promote vigorous plant establishment.

Key Ingredients and Benefits of Bolster MycoBio:

• Mycorrhizal fungi are living organisms that provide several benefits for their host plant. These organisms are entirely dependent upon their symbiotic relationship with plants for survival and consequently provide a number of services and materials to assure their host plant’s survival and productivity.  Suståne has chosen 4 specific strains of endo mycorrhizae that are most likely to form positive relationships with the majority of plant types you grow.  Upon colonization of the host plant, mycorrhizae begin to significantly increase the plant’s access to the soil resource pool by extending (literally miles of additional) microfilaments known as hyphae throughout the rhizosphere (root zone). These threadlike structures extract both soil moisture and plant nutrients from an enlarged area and from minute sites that are inaccessible to bare roots drawing water and nutrients from a volume of soil that is much greater than what the plant alone can access.  
• Bacillus is a genus of bacteria that are commonly found in soils.  The microorganisms help facilitate the cycling of nutrients, transforming them into plant-available forms for uptake by plants.  These microorganisms can also protect against certain soil-borne diseases, resulting in more resilient plants.
• Humates are naturally occurring, complex organic molecules that are formed as a result of the decomposition of plant and animal material which has been compressed for millions of years deep below Earth's surface.  Humates have numerous benefits, including being a rich source of carbon,  improving soil structure, and increasing root growth.

Recommended Use

Use BOLSTER MycoBio for rapid and resilient seedling establishment. The BOLSTER MycoBio formulation supports the growth of diverse crops in all types of growing environments. Ideal for transplant production in greenhouse and nursery systems as well as hydroseeding in erosion control applications and new turf establishment. MycoBio can be applied to new plantings of turfgrass, fruit, vegetable, and grain crops. 

INSTRUCTIONS FOR USE

Best used in combination with a Sustane-based organic fertility program using an N:P₂O₅ ratio that is greater than 2:1 over the entire grow cycle. 

Applications and Rates

Blend into growing media used for seed starting,
transplant production, and/or initial planting of rooted cuttings at 1 - 2 lb. per yd³ (.65-1.5 kg m³) of media. 

Greenhouse/Transplant Production:

For seed starting, transplant production, and/or initial planting of rooted cuttings, thoroughly incorporate into potting media using 1 - 2 lb. per yd³ (.65-1.5 kg m³). Increase to 3 lb. per yd³ (1.95 kg m³) when using propagation trays with < 20 cm³ cell volumes.  For smaller planting volumes, use 1.5 tablespoons per gallon (2.6 g per L) of potting media, or 1 cup per 2.8 ft³ (128 g per .26 m³) loose-filled bag of media.

Landscape and Garden Use:

Indoors, use 1.5 tablespoons per gallon (2.6 g per L) of the potting mix when establishing or replanting houseplants.  Outdoors, apply ½ cup per gallon (64 g per 3.8 L) of fill dirt when planting shrubs or trees. In garden beds, use just 1 teaspoon (2.5 g) of material in each transplant hole for small flower vegetable transplants. Alternatively, apply in-furrow using 1 lb.-2 lb. per 100 ft² (1-2 kg per 100 m²) of soil when planting vegetables, fruit, or flower gardens.
