The carbonate minerals and gypsum exert a dominating influence on soils inwhich they are present because of their relatively high solubility, and in the caseof the carbonates, their alkalinity and ...

Is calcium carbonate harmful to plants?

Calcium Carbonate (Limestone) Calcium carbonate, the chief component of limestone, is a widely used amendment to neutralize soil acidity and to supply calcium (Ca) for plant nutrition. The term "lime" can refer to several products, but for agricultural use it generally refers to ground limestone.

The effect of gypsum on bacterial activities in soils

as regards nitrification calcium carbonate exerted the most favorable action while gypsum had no effect. Sugar showed an increased azofication. Hart and Tottinghaa (18) in their work showed that sulfates as compared with soluble phosphates had very little effect on the soil flora. Pita (40) in his work with sulfur and calcium sulfate

Calcium in plants and soil

Calcium. Calcium is a secondary plant macronutrient and is vital for healthy plants. It is required for the formation of new cells so is needed in order for roots, stems and leaves to grow. It is also used by plants when they respond to pest and disease attacks.

Effect of gypsum content on soil water retention ...

Equivalent gypsum (EG), calcium carbonate equivalent (CCE), and other components (i.e., non-EG and non-CCE) in the studied 43 soil samples ranked by ascending EG.
