• Product Page Grid Blurb: A blend of endo mycorrhizae and beneficial bacteria, with humic acid and compost.

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.

Suståne 4-6-4 Compost Tea Bags

Suståne compost tea is designed to provide organic plant nutrition.

Suståne 4-6-4 Compost Tea Bags are prepackaged permeable fertilizer packs that are left to steep in containers with water to make a Compost Tea brew for topical application.

Suståne 4-6-4 Compost Tea bags come in two sizes, single-use 21-gram size for watering cans, or to be used as Root Zone Feeder Packs and reusable organic cotton bag 5 lb compost tea bags, which each make 50-100 gallons.

There are multiple benefits to using compost teas. More than supplementary nutrients, composts teas deliver humic substances that can act as biostimulants and active microorganisms that can contribute to nutrient cycling and the ecology of healthy soil.

Using compost teas may reduce the need to apply pesticides. Many reports indicate that compost teas increase plant tolerance to biotic and abiotic stresses, reducing the need for other inputs.

What is Compost Tea?

Compost tea is the result of adding high-quality compost that is rich in beneficial micro-organisms to water with the presence of oxygen and allows it to “brew”. When these microbes are provided with water, oxygen, and a food source the start to multiply rapidly, populating the “tea” with billions of beneficial microbes. Suståne 4-6-4 provides all the essential components of effective compost teas and has been proven to support improved plant growth. 

Microbiology from aerobic compost provides numerous benefits to plants and soil. Beneficial micro-organisms compete for resources with the disease-causing bacteria (pathogens) resulting in less disease pressure and healthier plants.

The microbes also go to work converting the nutrients from the compost to water-soluble, plant-available form. This process makes the organic nutrients more readily available and easier for plants to take up. Soluble nutrients result in a faster response from the plant. Some composts are very rich in nutrients resulting in a tea that works as a fertilizer as well as a soil enhancer. Other composts have very little nutrients and do not provide enough plant food alone.

Making high-quality compost tea can be difficult as composts tend to vary significantly in quality. Poorly made compost may contain minimal beneficial micro-organisms and could potentially carry harmful pathogens that could multiply when the compost tea is brewed. Low numbers of microbial populations or the presence of harmful pathogens are often the result of “compost” that was made without oxygen present (anaerobic) or did not have the proper ratio of carbon to nitrogen (C:N) to reach a temperature sufficient to kill harmful pathogens.

How Compost Tea is Used:

At the end of the brewing cycle, the water is teeming with beneficial micro-organisms and plant-available nutrients. This water can be sprayed over the plant leaves and roots and used to drench the soil. Plants treated with compost tea will generally look fuller, brighter, and with less disease pressure. Make an enriched compost tea for superior results. Once brewed, it blends well with Suståne’s Hi-N 12-0-1 WDF to make an enriched compost tea with superior characteristics!

How to Make High-Quality Compost Tea:

Compost Tea is simple to prepare. Add two 21 gram tea bags per gallon (42 grams), or a 5 lb. Compost Tea Bag per 50-100 gallons (190-380 L) of water, aerate and steep for 24 to 48 hours at 60°- 85° F (10° - 25° C).

Aeration during the brewing process increases the level of active microorganisms in the Compost Tea

Apply to plant leaves and roots. Apply the normal amount of water as you would when watering the plant.

• Use Compost Tea Brew within 36 hours of placing the teabag in the water. The brew will become anaerobic once the microbes have consumed all of the oxygen in the water.
• Use Compost Tea before plants begin to set fruit. Do not spray Compost Tea brew directly onto existing fruits and vegetables. 
• After all of the Compost Tea is used, the remaining pouch or compost inside the reusable 5 lb. Compost Teabag may be placed in the garden or on/in the soil to continue to benefit from the compost fertilizer or place the used Compost Tea pouch into an existing compost pile to jump-start the composting process.

Why Fertigation?

Water dispersible fertilizers greenhouse fertigation, hydroponics, foliar feeding, planting of field crops, and turf

Fertigation provides more precise control of plant-feeding. There are many systems and approaches for growing plants, and each has its benefits. Wherever water is provided through irrigation, additional nutrients can also be delivered. By precisely dosing plants with only the nutrients they need as they grow, there is reduced potential for nutrient loss in the growing system. That can mean better control of plant growth, greater nutrient use efficiency, and less waste.

Commercial nurseries and greenhouses grow plants with diverse nutritional needs. While a typical soil or constructed potting mixes can provide all of the nutrients a plant needs to grow, supplementing those matrices with different concentrations of key nutrients, particularly nitrogen, can improve the rate and quality of plant growth.

Turfgrass managers and landscapers sometimes need quick greening. In the green industries, people who produce and manage turfgrass know that color and thickness are key qualities demanded by many customers. Balanced nutrition also helps keep grass healthy and more tolerant of foot traffic and other environmental stresses.

Fertigation Rates and Application:

Suståne Hi-N 12-0-1 WDF in use with delivery systems

For Hydroponics & Greenhouse Fertigation

Use up to 2 lb. of Suståne WDF per 100 gallons of water for finished solutions with up to 300 PPM of N. To do so, prepare a base concentrate by thoroughly mixing 0.5 lb. powder per gallon of water (or 60 g per liter). This base concentrate can then be diluted into 50 to 150 volumes of water to obtain working solutions of various strengths. Working solutions can be applied regularly depending on crop demand and growing conditions.

For Field Crop Starter Fertilizer

For in-furrow and side-dress drench applications, apply up to 40 lb. of Suståne Hi-N WDF per acre in no less than 200 gallons (45 kg per hectare in no less than 780 liters of water) of solution. To do so, mix up to 0.2 lb. of powder with each gallon (or 25 g per liter) of water while filling the mixing tank. Ensure powder is fully dissolved before application. Apply within 4 hours of preparation. Rinse applicator tank and pump lines thoroughly with water immediately following application to avoid clogging.

For Foliar Feeding

For foliar applications to fruiting crops, apply up to 3 lb. of Suståne Hi-N WDF per acre using 100 gallons of water (3.5 kg per hectare using 1000 liters of water). To do so, prepare a base concentrate by thoroughly mixing 0.3 lb. of Suståne Hi-N WDF per gallon of water (36 g per liter). This base concentrate is then diluted 1:10 with water in the spray tank to prepare the working solution for foliar feeding. Apply 100 gallons per acre (or 1,000 liters per hectare) one to four times per season. Apply the working solution within 4 hours of preparation. Rinse sprayer thoroughly with water immediately following application to avoid clogging.

For Turf

For turf applications, use 0.9 lb. of Suståne Hi-N WDF per 1,000 ft² using 2 gallons of water (500 g per 100 square meters using 7.8 liters of water). To do so, mix in 0.45 lb. Suståne Hi-N WDF per gallon of water while filling the applicators reservoir tank. With constant agitation, apply 2 gallons of working solution per 1,000 ft² (7.5 liters per 100 square meters) of turf to provide 0.1 lb. of N per 1,000 ft². Apply the working solution within 4 hours of preparation. Rinse sprayer thoroughly with water immediately following application to avoid clogging.

Application rates and use instructions:

Application rates of Suståne water-dispersible fertilizers should be made based according to a crop’s nutritional needs and tolerance for salt stress. WDF should be diluted in water and mixed well prior to application. For best results, add package contents to fresh water in clean containers with mixing as described below. The preparation of a homogenous solution is critical to successful and consistent fertigation. It is highly recommended that growers prepare a base concentrate of Suståne’s WDF in a bucket of water and then mix the concentrated solution into a larger volume of reservoir water to ensure proper mixing prior to dispensing. Prepare a concentrate of 0.5 lb. of powder per gallon of water in your reservoir. Add the powder slowly while stirring until the required amount has gone into solution. Use a pre-filter screen on the reservoir's injector line. After the concentrate is fully mixed, let the solution sit for 15 minutes before placing the injector hose into the reservoir.

Make sure the intake end is not touching the bottom of the reservoir and allow the injector to pump all but 2% of the concentrate volume to avoid uptake of any contaminating grit that might rapidly clog intake screens. After fertigation, the remaining concentrate may be fully diluted and injected directly as part of the initial flush. Apply fertigation solutions ONLY when temperatures are above 50^oF (11^oC) and below 85^oF (30^oC). Commercial users should check the pH and EC of the prepared fertigation solutions to make sure they are within acceptable ranges for their specific crops.
