Nitroform 39-0-0 is a ureaform (urea-formaldehyde) slow-release nitrogen fertilizer for established lawns, trees, shrubs, and ornamental beds. It guarantees 39% total nitrogen, of which 28.5% is water-insoluble nitrogen that soil microbes release gradually over a period of months, so one application feeds steadily with far less soluble salt than the same nitrogen...

Organic Blood Meal 13-0-0 is a fast-release organic nitrogen fertilizer — dried bovine blood from USDA-inspected processing facilities, milled to a fine powder and lab-tested for heavy metals. At 13% nitrogen, it is one of the most concentrated organic nitrogen sources commonly used in gardens, with the fastest release profile of any...

Urea Fertilizer 46-0-0 is a concentrated prilled nitrogen fertilizer for soil application, delivering 46% actual nitrogen — among the highest concentrations of any dry nitrogen source. Each pound supplies about 7.4 ounces of actual nitrogen, more than double ammonium sulfate and roughly triple calcium nitrate, so less product is needed to...

Organic Feather Meal 12-0-0 is a slow-release organic nitrogen fertilizer made from hydrolyzed poultry feathers. It supplies 12% total nitrogen as water-insoluble keratin protein, released gradually over 3 to 4 months as soil microbes break it down — one of the longest natural nitrogen curves among common organic fertilizers. Because the nitrogen must...

Greenway Biotech Calcium Nitrate 15.5-0-0 supplies nitrogen and calcium together: 15.5% nitrogen (14.5% nitrate, 1% ammoniacal) and 19% calcium, from ammonium calcium nitrate double salt. Spread it dry as a vegetable sidedress, or dissolve it for drip fertigation and hydroponic recipes. Clemson and University of Georgia Extension call a calcium nitrate sidedress...

Greenway Biotech Ammonium Sulfate Fertilizer 21-0-0 supplies 21% nitrogen as ammonium and 24% sulfur in a water-soluble form. Use it where your lawn or crop needs these nutrients, including suitable blueberry and acid-loving plant programs. Nitrogen supports leafy growth, while sulfur contributes to amino acids and proteins. Ammonium sulfate can also...

Magnesium Nitrate Fertilizer 11-0-0 is a CDFA-registered, 100% water-soluble fertilizer that delivers two essential nutrients in a single application: 11% nitrate nitrogen and 9.6% magnesium. The nitrogen is supplied entirely as nitrate, so it is immediately plant-available with no microbial conversion step and stays available even in cool soils. Magnesium is the...

Cottonseed Meal 5-2-1 is a single-ingredient slow-release organic fertilizer derived from cottonseed processing. It delivers a complete macronutrient profile — 5% nitrogen, 2% available phosphate (P₂O₅), and 1% soluble potash (K₂O) — released gradually over 4–8 weeks as soil microbes decompose the organic matter, which largely eliminates the foliage burn risk of...

Pepper & Herb Fertilizer 11-11-40 is a premium, 100% water-soluble fertilizer formulated for the fruiting window in peppers and the harvest window in culinary herbs. The balanced 11% nitrogen and 11% available phosphate paired with very high 40% soluble potash supports fruit quality while sustaining the canopy through long fruiting cycles,...

Greenway Biotech Organic Alfalfa Meal 2.5-0-2.5 is a ground, plant-derived fertilizer for garden beds, rose beds, and soil preparation. It supplies nitrogen and potassium while adding organic matter to the soil. 2.5% total nitrogen: water-insoluble nitrogen from alfalfa meal, gradually made available through microbial activity. 2.5% soluble potash: potassium expressed as...

Greenway Biotech Cucumber Fertilizer 8-16-36 is a water-soluble fertilizer for cucumbers, squash, pumpkins, gourds, watermelon, cantaloupe, and the other cucurbits named on its label. It guarantees 8% nitrogen (6.5% nitrate, 1.5% ammoniacal), 16% available phosphate (P₂O₅), and 36% soluble potash (K₂O), with EDTA-chelated iron, manganese, zinc, and copper plus boron and...

<p>Greenway Biotech Lettuce Fertilizer 8-15-36 is a water-soluble fertilizer for lettuce, kale, spinach, cabbage, broccoli, bok choy, chard, and the other leafy crops named on its label. It guarantees 8% nitrogen (7.5% nitrate, 0.5% ammoniacal), 15% available phosphate (P₂O₅), and 36% soluble potash (K₂O), with EDTA-chelated iron, manganese, zinc, and copper...

Organic Kelp Meal 2-0-4 is a slow-release soil amendment and biostimulant made from Ascophyllum nodosum, a cold-water seaweed. It supplies 2% nitrogen and 4% soluble potash (K₂O) along with 60+ ocean-sourced trace minerals — iron, manganese, zinc, copper, boron, molybdenum, and more — in naturally balanced proportions, plus naturally occurring auxins, cytokinins,...

Organic Crustacean Meal 4-0-0 is a slow-release soil amendment made from dried, ground crab and shrimp shells — a recycled byproduct of the seafood processing industry. It supplies 4% organic nitrogen, 12% calcium, and 1.3% magnesium, along with naturally occurring chitin, the structural fiber found in crustacean exoskeletons. The nitrogen is held...

Monoammonium Phosphate (MAP) 12-61-0 is a technical-grade, 100% water-soluble fertilizer and one of the most concentrated water-soluble phosphorus sources available. Each pound delivers 61% available phosphate (P₂O₅) and 12% ammoniacal nitrogen, dissolving completely with no residue. Phosphorus supports root development, flowering, and fruit set, and the ammonium-form nitrogen helps acidify the...

Monoammonium Phosphate (MAP) 11-52-0 is a CDFA-registered, agricultural-grade granular fertilizer that delivers high-analysis phosphorus for soil application. Each pound supplies 52% available phosphate (P₂O₅) and 11% ammoniacal nitrogen in uniform granules that spread cleanly through rotary and drop spreaders. Phosphorus supports root development, flowering, and fruit set, and the ammonium-form nitrogen...
