The 15.5% nitrogen runs mostly as nitrate, at 14.4% nitrate to 1.1% ammoniacal, alongside 19% calcium. Nitrate feeds fast and keeps calcium moving into new growth, so a greenhouse or indoor crop holds firm cell walls. It dissolves clear and colorless, with only 0.03% insoluble matter, so it runs clean through fertigation lines and stock tanks.\u003c\/p\u003e\n\u003ch2\u003eWater Soluble Calcium for Fertigation and Foliar Feeding\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eAs a water soluble calcium fertilizer, it works through fertigation or as a foliar feed on greenhouse and soilless crops. Steady calcium is what heads off blossom end rot in tomato and pepper and tip burn in lettuce. Most growers run it in its own stock tank, kept apart from phosphates and sulfates that would drop calcium out of solution. That keeps the feed clean whether the crop sits on a greenhouse bench, in an indoor garden, or in an open field.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e15.5-0-0 with 19% Ca:\u003c\/strong\u003e Nitrate-led nitrogen and calcium in one soluble feed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully water soluble:\u003c\/strong\u003e Clear, colorless solution with only 0.03% insoluble matter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGreenhouse grade:\u003c\/strong\u003e Built for fertigation of soilless and greenhouse crops\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFertigation or foliar:\u003c\/strong\u003e Runs through drip lines or as a foliar spray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStronger cell walls:\u003c\/strong\u003e Steady calcium guards against blossom end rot and tip burn\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;
