When the treated dolomite was used as a catalyst to produce glycerol carbonate via a transesterification reaction of glycerol and dimethyl carbonate, the The pH of the original soil (4.92) steadily increased to 5.35 and 5.45 at day 105 in rice and green bean straw treatments, respectively. Application of dolomite increased pH to a maximum value of 6.35 in the rice straw + dolomite and 6.55 in the green bean straw + dolomite amended soil at day 105 following establishment of the trial.The interactive effects of dolomite application and straw

Furthermore, Ca and Mg combine with HCO 3 − and lead to Ca(HCO 3) 2 and Mg(HCO 3) 2 formation. As a Dolomite application to acidic soils: a promising option for

It is also finding applications in float glass production, which will drive the global dolomite mining market forward. In the pottery and ceramic industries, dolomite is used as a glazing ingredient. In industries, raw dolomites are being replaced by igneous rock containing olivine minerals, stifling the growth of the dolomite market.For instance, the application of dolomite (DM) caused an increase in CO 2 emissions [53]. Likewise, application of DM also affects the soil pH and CH 4 oxidation and production from soils [10]. The application of DM increases soil pH, which in turn stimulates the methanotrophs' activities and increases CH 4 [65].How does dolomite application affect the greenhouse gases

Uses. Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces. The use of dolostone as a flux has increased, especially since environmental contamination has Dolomite–palygorskite (DP) composed of dolomite and palygorskite is a kind of special palygorskite.

The results indicated that dolomite application increased SOC mineralization via enhancing DOC production and stimulating microbial growth and activity, which resulted from the increase in soil pH. Moreover, the effect was greater for the finer particle size, suggesting that the particle size of lime material has the role in regulating the SOCPolymers are being used in many applications all around the world. However, there are some drawbacks in the properties of polymers that could hamper their usage in certain applications. Therefore, a new material polymer composite was introduced.

The application of DM also had significant effect on the CH 4 emissions (Fig. 1 b). The maximum CH 4 emissions (99.97 %) were recorded in DM applications > 10 t ha −1 and DM applications of 0–10 t ha −1 reduced the CH 4 emissions by 44.73 % (Fig. 1 b)..
