The nitrogen is almost entirely fast-acting nitrate, plant-available the moment it dissolves, and the formula contains no phosphate or potash.\u003c\/p\u003e\n\u003cp\u003eNitrogen drives chlorophyll production, protein synthesis, and vegetative growth, while calcium supports cell-wall structure in fruit and leaf tissue that expands fastest. Nitrate is also the preferred nitrogen form for calcium-sensitive crops, since ammonium competes with calcium for uptake at the root. Calcium nitrate is widely used as a sidedress for tomatoes, peppers, and cucurbits, as a clean phosphate-free calcium and nitrate source for hydroponic and fertigation systems, and as a low-rate foliar supplement during rapid growth. It dissolves completely with no residue and has a near-neutral effect on soil pH.\u003c\/p\u003e\n\u003cp\u003eOne essential handling rule: calcium and concentrated phosphate or sulfate fertilizers should never be combined in the same stock tank, as they form an insoluble precipitate — keep calcium nitrate in a separate stock tank and combine only in the dilute solution. Water in dry applications, apply foliar sprays in cool conditions, and store sealed and dry, as the product is hygroscopic.\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":51440691282215,"sku":"701748873726","price":24.99,"currency_code":"USD","in_stock":true},{"title":"5 Pounds","offer_id":51440691314983,"sku":"701748874051","price":31.99,"currency_code":"USD","in_stock":true},{"title":"10 Pounds","offer_id":51440691347751,"sku":"701748874075","price":49.99,"currency_code":"USD","in_stock":true},{"title":"25 Pounds","offer_id":51440691380519,"sku":"701748874044","price":89.99,"currency_code":"USD","in_stock":true},{"title":"50 Pounds (or 2 x 25 pound bags)","offer_id":51440691413287,"sku":"018227120951","price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/4571\/3959\/files\/Ammonium_Calcium_Nitrate_Fertilizer_15.5-0-0_Solution_Grade.jpg?v=1779970730","url":"https:\/\/giftfromtheland.shop\/fr\/products\/calcium-nitrate-fertilizer-15-5-0-0-ammonia-calcium-nitrate-15-5-0-0","provider":"Gift From The Land","version":"1.0","type":"link"}
