A natural based fertilizer with a synergistic blend of plant biostimulant, humic acid, and mycorrhizae ideal for core aerification, sodding and turf establishment.
BOLSTER GRANULAR 4-4-4 plus Iron provides a blend of organic nutrients, beneficial microbiology, bio-stimulants, iron and V.A. Mycorrhizae that improves all turf and landscape plantings. Carefully selected arbuscular mycorrhizal species can promote greater access of plant roots to soil nutrients and water. 3% chelated iron promotes greening and rapid root development and seaweed extract, humic acid, and compost-based microorganisms act as biostimulants that enhance root growth and improve overall plant health.
BOLSTER is recommended for use in all renovation, pre-plant, seeding, and amendment requirements to turfgrass surfaces. It is best applied after aeration, either hollow coring or solid tining to incorporate the product into the soil surface, to maximize the benefits of its microbial diversity and V.A. Mycorrhizae.
Suståne products are derived from biologically stable humus-rich compost and contain both water soluble nitrogen (WSN) and slow release nitrogen (SRN), beneficial microbiology, and all 17 elements essential for plant photosynthesis. With a near-neutral pH, a low salt index and low ammonium nitrogen percentage, Suståne will not cause seedling stress or plant fertilizer “burn”. Suståne products increase soil cation exchange capacity (CEC) by supplying humates and stable organic matter. Suståne’s organic and blended natural fertilizers provide all soil types with additional buffering capacity, allowing for more consistent and productive growth.
- Provides quick green up followed by six to eight weeks of even color and growth.
- Strengthens plants tolerance against hot, dry conditions.
- Improves buffering against changes in soil pH.
- Increases the soil’s ability to suppress plant pathogens and soil contaminants.
- Increases soil porosity and stability for greater root development and water holding capacity.
- Contains beneficial V.A. Mycorrhizae - see below.
- Contains Ascophyllum nodosum seaweed.
- BOLSTER G is extremely safe and will not burn or discolor turfgrass.
- Reduces transplant shock.
“V.A. Mycorrhizae” refers to the species of fungi that forms beneficial associations with most plant species. 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. It affects available soil nutrition, plant carbon transfer, and increases water and P utilization and the physical structure of the soil and the numbers of and types of other organisms present in the soil. BOLSTER contains 3.52 propagules per gram of Suståne's proprietary blend of four different species of V.A. Mycorrhizae.
