<p>Greenway Biotech Chelated Iron DTPA is a fully chelated, water-soluble powdered iron fertilizer with a guaranteed 11% iron, all of it chelated by DTPA. It prevents and corrects iron deficiency (yellowing between green veins on the youngest leaves) in vegetable, field, tree, vine, and ornamental crops, and supplies the iron line in...

Citrus & Avocado Fertilizer 14-6-4 is a professional-grade, 100% water-soluble fertilizer formulated for citrus and avocado trees in the high-pH soils common across California, Arizona, and Texas. Its 14-6-4 NPK uses a triple nitrogen blend — ammoniacal, urea, and nitrate — for both immediate and sustained feeding, with the ammoniacal fraction creating...

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...

Organic Azomite 0-0-0.2 Micronized is an OMRI Listed natural mineral soil amendment mined from a single hydrated sodium calcium aluminosilicate (HSCAS) deposit in central Utah — volcanic ash that settled into a mineral-rich seabed roughly 30 million years ago. One product supplies approximately 70 trace and ultra-trace elements, including silica, calcium, magnesium,...

Greenway Biotech Chelated Copper EDTA is a water-soluble copper fertilizer with a guaranteed 14% copper, all of it chelated by EDTA. It supplies one micronutrient for two jobs: correcting a copper shortage that a soil or tissue test has confirmed, and providing the copper line in a complete hydroponic or fertigation recipe. Copper is a cofactor...

Iron chlorosis is usually a pH problem, not a missing-iron problem, so the chelate matters as much as the iron. Greenway Biotech Chelated Iron EDTA is a water-soluble powder guaranteeing 13.2% iron, all of it held by EDTA — more iron per pound than DTPA or EDDHA chelates, and the right choice for...

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...

K-Mag Fertilizer 0-0-22 (sulfate of potash magnesia, also called langbeinite) is a naturally mined mineral fertilizer that delivers three nutrients in a single soil-applied product: 22% soluble potash (K₂O), 11% magnesium, and 22% sulfur, with less than 2.5% chloride and no nitrogen. Potassium supports fruit size, sugar movement, and stress tolerance; magnesium...

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...

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,...

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...

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...

Greenway Biotech Strawberry Fertilizer 8-12-32 is a water-soluble fertilizer for strawberries, raspberries, blackberries, and the other berries and fruit trees on its label. It guarantees 8% nitrogen (7.2% nitrate, 0.8% ammoniacal), 12% available phosphate (P₂O₅), and 32% soluble potash (K₂O), with EDTA-chelated iron, manganese, zinc, and copper plus boron and molybdenum....

Manganese Sulfate Fertilizer is a high-purity manganese sulfate monohydrate (MnSO₄·H₂O) micronutrient supplying 31% elemental manganese and 18% sulfur — one of the most concentrated, fully water-soluble manganese sources available for preventing and correcting manganese deficiency. Manganese is an essential micronutrient: it sits at the center of the water-splitting complex in photosynthesis...

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...

Organic Bone Meal 3-15-0 is a steam-processed bovine bone meal soil amendment supplying 15% available phosphate (P₂O₅) and 24% calcium — one of the highest organic calcium concentrations in a single amendment — plus a small amount of slow nitrogen. Phosphorus drives root development, flowering, and fruit set, and in bone meal it...
