{"product_id":"chelated-iron-dtpa-fertilizer","title":"Chelated Iron DTPA Fertilizer","description":"\u003cp\u003eChelated Iron DTPA 11% is a 100% water-soluble iron fertilizer that corrects iron chlorosis in neutral to moderately alkaline conditions. Its guaranteed analysis is 11% iron held as a DTPA chelate, which keeps the iron plant-available up to roughly pH 7.5 — past the point where standard EDTA iron chelates begin to lose effectiveness.\u003c\/p\u003e\n\u003cp\u003eIron deficiency is usually caused by soil pH locking up iron rather than a true shortage, and it shows as interveinal yellowing on the youngest leaves first. DTPA's stronger hold makes this product a practical choice for neutral-to-alkaline soils, alkaline or bicarbonate-rich irrigation water, and situations where an EDTA-based iron has failed. It dissolves completely with no residue for soil drench, foliar spray, hydroponic, and aquaponic use.\u003c\/p\u003e\n\u003cp\u003eConfirm the deficiency and check pH before applying, since a chelate corrects iron availability but does not lower soil or water pH. Fe-DTPA breaks down under UV light, so keep reservoirs shaded. For foliar use, spray in early morning or late afternoon, and do not exceed recommended rates — excess iron can interfere with manganese and zinc uptake.\u003c\/p\u003e\n\u003cp\u003eCDFA registered and third-party lab tested for heavy metals, with results consistently well below required limits.\u003c\/p\u003e","brand":"Greenway Biotech, Inc.","offers":[{"title":"1 Pound","offer_id":44274213552216,"sku":"018227120920","price":31.99,"currency_code":"USD","in_stock":true},{"title":"2 Pounds","offer_id":44274213584984,"sku":"018227121453","price":49.99,"currency_code":"USD","in_stock":true},{"title":"5 Pounds","offer_id":44274213617752,"sku":"018227121460","price":109.99,"currency_code":"USD","in_stock":true},{"title":"25 Pounds","offer_id":44274213650520,"sku":"018227121477","price":309.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0711\/9165\/8584\/files\/Chelated_Iron_DTPA_Fertilizer_1_Pound_2b9f07e7-fc98-4ac3-bfdc-cdcad4328896.png?v=1782322958","url":"https:\/\/gridwiseliving.com\/products\/chelated-iron-dtpa-fertilizer","provider":"Gridwise Living","version":"1.0","type":"link"}
