It directly influences fruit firmness, disease resistance, and post-harvest quality. Unlike mobile nutrients, calcium cannot be redistributed within the plant, so continuous supply is critical—especially during rapid growth and fruit development.\u003c\/p\u003e\n\u003cp\u003eThe nitrate form of nitrogen in Haifa Cal GG promotes vigorous vegetative growth and enhances calcium uptake. Nitrate nitrogen is readily absorbed by plants and supports optimal crop development without the pH complications associated with ammonium-based fertilizers.\u003c\/p\u003e\n\u003ch3\u003ePreventing Calcium Deficiency Disorders\u003c\/h3\u003e\n\u003cp\u003eCalcium deficiency causes significant economic losses in greenhouse production through disorders like blossom end rot (tomatoes, peppers), tip burn (lettuce, cabbage), and fruit cracking. These disorders occur even when calcium levels are adequate in the growing media, because calcium movement depends on transpiration and can be limited during rapid fruit expansion or high humidity.\u003c\/p\u003e\n\u003cp\u003eRegular application of Haifa Cal GG through fertigation and strategic foliar sprays ensures adequate calcium reaches developing tissues, preventing deficiency symptoms and maximizing marketable yield.\u003c\/p\u003e\n\u003ch3\u003eCompatibility \u0026amp; Mixing\u003c\/h3\u003e\n\u003cp\u003eHaifa Cal GG can be mixed with most water-soluble fertilizers except those containing sulfates or phosphates. When preparing concentrated stock solutions, always keep calcium nitrate separate from sulfate and phosphate sources to prevent precipitation.
