The presence of pulp in cocoa seeds is known to inhibit seed germination and seedling growth. conventional method removing from done mechanically by rubbing the with ash. Conventional removal has disadvantages, such as being less practical potentially damaging surface. Therefore, it necessary try chemically soaking a lime solution (CaCO3). This study aims determine effect duration CaCO3 differe...
The thermal treatment of limestone (mainly CaCO3) to produce lime (CaO) is a major contributor CO2 emissions and the literature on decarbonising industry scarce. Subsequent hydration would lead synthesis slaked/hydrated Ca(OH)2; production tonne Ca(OH)2 emits ?1.2 tonnes arising mainly from process chemistry fossil fuel combustion. Carbon Capture & Storage (CCS) technologies are currently belie...
Introduction: The recent discovery of carbonaterich outcrops in the Nili Fossae region of Mars using data returned by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument [1] as well as indications of 2-3% carbonate in alkaline soils at the Phoenix landing site [2] have brought into question the hypothesis that much of martian history has been dominated by an acidic weath...
Dolomite [CaMg(CO3)2] is used widely for soybean, Glycine max (L.) Merr. production in Japan to amend soil pH, although magnesium (Mg) the dolomite can inhibit soybean growth and yield. The aim of this study was determine effect Mg on a paddy – upland rotation field 2019–2020 by comparing application calcite (CaCO3). test included three replications with lime applications: control (no lime), do...
introduction cadmium is one of the most important environmental pollutants that can be resulted from different ways. it can easily contaminate soil and water resources. since phosphate ions for stable complexes are available with cations such as pb and cd, so it can cause a decrease in the solubility and mobility of heavy metals in soil. liming is the most widely used treatment that leads to pr...
Phosphorus (P) losses from clay soils can be mitigated by introducing measures for improving soil structure. These include structure liming, where a mixture of CaO or Ca(OH)2 and CaCO3 is added to the soil. In field experiment with separately tile-drained plots on loam in Sweden, we examined effects liming leaching total-P, phosphate P (PO4-P) total nitrogen (N) during three years after initial...
This study presents the influence of cement and lime industry on physical chemical properties arable soils. In spite using modern forms environmental protection against dust emissions, this type causes unfavourable phenomenon excessive alkalisation soil. process is relatively rare in Poland. However, Świętokrzyskie Province, it has been responsible for largest transformation soils recent years....
The parental material of soils in the Qilian Mountains of northwest China is mainly aeolian loess containing CaCO3 which may remain in soils under the semiarid-arid climate. To disclose the CaCO3 characteristics change with the altitude and the terrain attributes, we surveyed 18 soil profiles in an altitude sequence from 3076 m to 4510 m in the Hulugou Watershed in the Qilian Mountains, measure...
