Harvest Supreme is an organic soil amendment developed by G&B Organics, featuring a carefully balanced formula of natural components designed to enrich garden soil. This blend is intended to improve the overall health and productivity of vegetable gardens and flower beds. The ingredients are OMRI-certified, meaning they are approved for use in organic gardening and are free from bio-solids or sewage sludge.
The Primary Components of Harvest Supreme
Recycled Forest Products and Bark Fines
These materials form the foundational bulk of the soil amendment, providing a porous, airy structure. This structural improvement is crucial for root health, allowing for better aeration and water penetration. As they decompose over time, they contribute to the soil's organic matter, enhancing its long-term fertility and water-holding capacity.
Composted Chicken Manure
Making up 15% of the total blend, this is one of the most potent ingredients in Harvest Supreme. Composted chicken manure is a nitrogen-rich nutrient source that promotes vigorous, lush growth in foliage and helps green up plants quickly. The composting process ensures that the manure is stable and less likely to burn plants compared to raw manure.
Worm Castings
Often called "black gold" by gardeners, worm castings are the rich, fertile excrement of earthworms. They introduce beneficial microbes, improve soil structure, and provide a slow-release source of nutrients that plants can easily absorb.
Bat Guano
This natural fertilizer is sourced from bat droppings and provides a potent, balanced source of nitrogen, phosphorus, and potassium, all essential macronutrients for plant growth. It contributes to both strong root development and plentiful flowering and fruiting.
Kelp Meal
Derived from dried seaweed, kelp meal adds vital trace minerals and hormones that stimulate plant growth and increase resistance to pests and disease. It is an excellent source of micro-nutrients often missing in typical garden soils.
Mycorrhizae
This crucial ingredient is a beneficial fungus that forms a symbiotic relationship with plant roots. Mycorrhizae effectively expand the plant's root system, allowing it to access water and nutrients from a larger soil area. This significantly boosts nutrient uptake and improves plant vigor.
Oyster Shell Lime
Included as a pH adjuster, oyster shell lime helps to balance the soil's acidity. It works to slowly raise the soil pH, creating an optimal environment for most vegetables and flowers to thrive. The added calcium also strengthens plant cell walls, leading to healthier, more robust growth.
Rice Hulls
Rice hulls are a lightweight material that improves soil structure by preventing compaction. They also aid in drainage, ensuring that roots do not become waterlogged and promoting healthy root oxygenation.
Comparison of Harvest Supreme vs. Standard Compost
| Feature | Harvest Supreme | Standard Garden Compost |
|---|---|---|
| Nutrient Richness | Highly concentrated with specific nutrient-dense ingredients like chicken manure, bat guano, and kelp meal. | Varies widely based on source materials; generally lower in concentrated nutrients. |
| Microbial Activity | Enhanced with beneficial mycorrhizae and worm castings for active soil life. | Dependent on the composting process, may or may not contain beneficial fungi. |
| pH Regulation | Includes oyster shell lime to actively adjust and stabilize soil pH. | Provides some buffering capacity but does not actively regulate pH. |
| Soil Structure | Contains a balanced mix of coarse and fine materials to loosen clay or bind sandy soils. | Improves soil structure but may be less specialized for certain soil types. |
| Application | Specifically formulated for use as an amendment, mixed into native soil for garden beds. | Can be used as a soil amendment or as a mulch layer. |
Proper Application for Maximum Benefit
To ensure your plants receive the full benefits from Harvest Supreme, proper application is key. For new garden beds or before transplanting, mix the amendment into your native soil to a depth of at least 6-12 inches. For existing plants, it can be used as a topdressing, applying a layer around the base of the plant. For best results, follow the coverage instructions on the packaging, which for a 2 cubic foot bag often suggests amending around 20 square feet.
Conclusion: The Holistic Approach to Soil Health
Harvest Supreme provides a comprehensive, organic solution for gardeners seeking to improve their soil quality and boost plant performance. Its blend of high-quality ingredients—from nutrient-rich chicken manure and guano to the structural support of forest products and bark fines—creates a highly favorable environment for growth. The inclusion of beneficial mycorrhizae and pH-balancing oyster shell lime sets it apart from simpler soil additives, offering a holistic approach to creating a thriving garden ecosystem. For gardeners focused on organic and productive cultivation, understanding what are the ingredients in Harvest Supreme confirms its value as a foundational soil enrichment product.
