Foliar application is the quickest remedy for acute calcium deficiency, as plants absorb nutrients more efficiently through leaves than through roots. How Do You Fix Calcium Deficiency In The Soil – 15 Ways? These fertilizers help ensure the proper addition of nutrients in the soil and help maintain soil acidity, all necessary for healthy plants. Lime serves to increase the pH, by modifying the balance between acidity and alkalinity.

All soils contain calcium ions (Ca 2 +) and magnesium (Mg 2 +) cations (positively charged ions) attracted to the negative exchange sites on clays and organic matter (cation exchange complex of the soil). Try these 5 gentle back stretches and find relief. References The predominant sources of acidity are the acid-forming cations, hydrogen and, where it is significant, aluminum 4. Epsom salt is magnesium sulfate, which also might interest you for magnesium. If you need your pH to remain stable, use gypsum. Calcium nitrate can also be used as a source of calcium for soil.

Add calcium to your soil easily by applying eggshells or soil additives to it. 5mL equals one teaspoon. One other option is using a calcium-magnesium formula, calcium acetate, or calcium magnesium acetate to quickly relieve a calcium deficiency.

Sprinkle your ground eggshells or soil additive onto your soil or use a fertilizer spreader to cover large areas. It will raise your pH (and that's usually what people use lime for).
