Limestone

There is considerable evidence of replacement of limestone by dolomite, including sharp replacement boundaries that cut across bedding. The process of dolomitization remains an area of active research, [54] but possible mechanisms include exposure to concentrated brines in hot environments ( evaporative reflux ) or exposure to diluted seawater in delta or estuary environments ( Dorag dolomitization ). [55]

Dolomitic Limestone

Dolomitic Limestone

Research has shown that dolomitic limestone and slow-release fertilizer are useful during propagation because, as soon as roots are initiated, nutrients are available to the plant. Nutrient mist has been used on foliage plant cuttings, but the high propagation temperatures are conducive to algal growth, especially on the slower-rooting cuttings, which can create a serious problem on leaves and reduce overall quality.
