It is one of the most concentrated chloride-free potassium sources available.\u003c\/p\u003e\n\u003cp\u003ePotassium regulates water movement, enzyme activity, and sugar transport into developing fruit, supporting fruit size, color, firmness, and storage quality. The chloride-free chemistry makes this product well suited to quality-sensitive and chloride-sensitive crops such as tomatoes, peppers, berries, grapes, potatoes, citrus, and tobacco, and to recirculating hydroponic systems where chloride would otherwise accumulate. The 17% sulfur is supplied as plant-available sulfate, supporting amino acid synthesis without a separate amendment.\u003c\/p\u003e\n\u003cp\u003eIt dissolves cleanly for soil, foliar, fertigation, and hydroponic use — keep it in Tank B, separate from calcium-containing fertilizers, since combining them in concentrated stock causes precipitation. Pre-dissolve in warm water before injecting, and for foliar use, spray in early morning or late afternoon and keep concentrations modest to avoid leaf burn.\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":"2 Pounds","offer_id":51440658383143,"sku":"018227120890","price":21.99,"currency_code":"USD","in_stock":true},{"title":"5 Pounds","offer_id":51440658415911,"sku":"0701748874235","price":34.99,"currency_code":"USD","in_stock":true},{"title":"10 Pounds","offer_id":51440658448679,"sku":"018227120524","price":49.99,"currency_code":"USD","in_stock":true},{"title":"25 Pounds","offer_id":51440658481447,"sku":"0701748874297","price":88.99,"currency_code":"USD","in_stock":true},{"title":"50 Pounds (2 X 25 Pounds)","offer_id":51440658514215,"sku":"018227120531","price":173.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/4571\/3959\/files\/PotassiumSulfateW_S.jpg?v=1779969834","url":"https:\/\/giftfromtheland.shop\/products\/potassium-sulfate-fertilizer-0-0-53","provider":"Gift From The Land","version":"1.0","type":"link"}
