Ingredient Library
We don't use fillers. Every ingredient earns its place — chosen for what it feeds in the soil, not just what it delivers to the plant.
The philosophy: Fertilizer that feeds the microbiology in your soil. Feeding the microbes, nematodes, and fungi that feed your plants.
Part One
The physical foundation of every mix — chosen for structure, drainage, and biological compatibility. These five components create the environment where chemistry and biology can thrive.
Provides excellent water retention, holding significantly more water than sandy soil, which reduces watering frequency and improves drought resilience. Its fibrous, porous texture creates air pockets, improving aeration, preventing compaction, and encouraging healthy root development. Coco fiber is pH neutral and supports enhanced nutrient retention and delivery to plants.
Enhances moisture retention significantly, proving especially valuable in sandy soils and potting mixes. It improves soil structure by loosening clay and adding cohesiveness to sand, increasing aeration and reducing compaction. Peat moss is naturally acidic, which helps lower soil pH for acid-loving plants.
A lightweight, porous volcanic glass that creates air pockets in the soil, preventing compaction and facilitating oxygen movement to roots. This improves aeration, promotes strong root growth, and enhances nutrient uptake. It also improves drainage while retaining a modest amount of moisture, balancing hydration without waterlogging.
A porous volcanic rock that significantly improves drainage and aeration by creating air pockets and preventing compaction. Its sponge-like structure also absorbs and retains excess water, releasing it gradually as the soil dries. Pumice contains trace minerals that are slowly released, providing micro-nutritional support to plants over time.
Adds essential organic matter, which improves soil structure, aeration, and water infiltration by promoting stable soil aggregates. It is rich in slow-release macro and micronutrients, enhancing the soil's capacity to retain nutrients. Compost also increases microbial diversity and abundance, fostering beneficial organisms that cycle nutrients and suppress pathogens.
Part Two
21 organic amendments selected for biological synergy — not just raw NPK numbers. Each ingredient feeds a different layer of the soil food web, creating the cascade of microbial activity that makes organic growing so effective long-term.
Why so many ingredients? Because healthy soil isn't fed from a single source. Fungi, bacteria, nematodes, and protozoa each require different food. A complete amendment blend feeds the whole ecosystem — and a thriving ecosystem feeds your plants.
Nutrient-rich fertilizer containing readily available essential nutrients (N, P, K, Ca, S, Mg) and concentrated nitrates. They improve soil structure, aeration, and water retention, while introducing beneficial microbes and humic acid for enhanced nutrient absorption. Worm castings boost germination, seedling growth, and plant resistance to diseases, pests, and environmental stresses.
Rich in phosphorus, potassium, carbon, and nitrogen, plus silica and chitin, stimulating vigorous root, flower, and foliage growth. It supplies readily available and slow-release nutrients. Seabird guano acts as a biostimulant, increasing microbial activity, improving water retention, and enhancing nutrient cycling.
Daley's Mix includes extra 8-3-1 bat guano
A potent organic fertilizer high in nitrogen, phosphorus, and potassium, with micronutrients like boron, calcium, and iron. It improves soil texture, balances moisture, stimulates soil microflora, acts as a slow-release fertilizer, and may aid in flushing soil toxins. Daley's Mix includes an additional 10 lbs of 8-3-1 high-phosphorus bat guano per yard for enhanced flowering and yield.
A rich source of over 70 micronutrients and trace minerals, plus natural growth hormones that stimulate root growth and nutrient uptake. It improves soil structure and moisture retention, supports microbial activity, boosts plant immunity, and increases stress resistance.
A good source of phosphorus, essential for robust root development, flowering, and fruit production. It also provides calcium for strong plant cell walls. As a slow-release fertilizer, it provides nutrients over about three months, promoting strong root growth and vibrant blooms.
A concentrated source of nitrogen and amino acids derived from whole fish. It breaks down quickly in the soil, delivering fast-available nutrients while stimulating microbial activity. Fish meal improves overall plant vigor and is especially effective during the vegetative growth phase when nitrogen demand is highest.
A slow-release nitrogen source, providing a steady supply for lush, green, leafy growth throughout the season. It also improves soil structure and supports microorganisms as it breaks down, enhancing soil fertility and nutrient availability over time.
A mineral amendment providing potassium and over 25 trace elements with a slow, gentle release over years. It improves soil structure and water retention in both clay and sandy soils and enhances cation exchange capacity.
Contains macro and micronutrients, plus a growth hormone (triacontanol) that stimulates growth, branching, and fruit size. It conditions soil, attracts earthworms and beneficial microbes, and contains saponins that can help repel pests.
A high-nitrogen organic source that releases nutrients slowly, providing a sustained supply for lush foliage. It improves soil structure and drainage and increases organic matter by feeding soil microbes.
A concentrated, rapid organic nitrogen source essential for vegetative growth and chlorophyll production. It stimulates compost decomposition and can help repel herbivores like deer and rabbits.
Primarily a source of phosphorus for robust root development and calcium for strengthening plant cell walls. It's a slow-release fertilizer beneficial for root vegetables and seedling establishment.
Primarily calcium carbonate, acting as a liming material to raise soil pH and neutralize acidity. It improves nutrient balance by increasing calcium and stimulates microbial biomass and enzyme activities.
A source of slow-release nitrogen, phosphorus, and high levels of calcium. It contains chitin, which feeds microbes that consume soil insects and root-damaging nematodes and helps fight root rot and mildew.
A balanced organic fertilizer rich in nitrogen and phosphorus, with nutrients rapidly available due to quick breakdown. It also contains significant calcium which improves cell wall strength and can improve soil structure.
A balanced, low-chloride, pH-neutral fertilizer providing potassium, magnesium, and sulfur. Potassium is vital for water regulation, magnesium for chlorophyll production, and sulfur for protein synthesis. It supports overall crop vigor and is safe for salt-sensitive plants.
Provides plant-available calcium and sulfur and improves soil structure. Calcium ions help hold soil particles together, reducing surface crusting and improving aggregation, especially in sodic or high clay soils.
Used to raise soil pH in acidic soils and supply magnesium and calcium. It neutralizes acidity and provides essential magnesium for chlorophyll production and calcium for cell wall development.
Derived from Leonardite Shale, humic acids significantly increase the activities of soil microflora, serving as a food source for microbes. This enhances biological activity, improves fertilizer efficiency, soil structure, and water retention. Think of humic acids as a force multiplier for every other amendment in the blend.
A beneficial fungus (Rhizophagus Intradices) that forms a symbiosis with roots, enhancing nutrient uptake — especially phosphorus, nitrogen, and potassium. It improves water absorption, increases resistance to environmental stresses, improves soil structure, and boosts plant growth. Mycorrhizal networks effectively extend the root system many times over.
A natural mineral product for remineralizing soil with a broad spectrum of trace minerals and micronutrients lost through modern agriculture. It improves soil vitality, plant health, structure, moisture retention, drainage, and can help raise pH in acidic soils. Glacial rock dust is the long-game ingredient — building soil mineral wealth for seasons to come.

Why It Matters
Synthetic fertilizers feed the plant directly — bypassing the soil food web entirely. Organic amendments like these feed the microbes, fungi, nematodes, and protozoa that have evolved over millions of years to deliver nutrients in exactly the form your plants need.
When you see 21 amendments in a blend, you're looking at 21 different food sources for 21 different layers of a living ecosystem. That's what makes our mixes work — not chemistry, but biology.
