However, mechanisms of K release in calcareous
soils may differ because of the occurrence of Ca and magnesium (Mg) carbonates that affect the extracting solutions in the short term.
nature can be attributed to the hindering of dioxins sorption to the local soils.
The high frequency of encrustation of D, ohioensis ossicles by small, calcareous
tubes was not previously documented in the initial description and interpretation of this taxon.
The Catatumbo sequence studied in this research was deposited from Aptian to Coniaician, where succession of tectonic events along with right environmental conditions allowed sedimentation of several calcareous
lithologies, resulting in a very rich petroleum system which have been producing hydrocarbon since the beginning of the last century.
The data obtained on the reattachment of fronds, number of SADs, survival, and growth rates were submitted separately by a two-way ANOVA to detect possible differences between substrates (calcareous
and rocky) and the distinct life phases of C.
These mortars have been compared with those manufactured with coarse and fine commercial calcareous
aggregates in terms of mechanical, microstructural, and durability properties.
Using a NanoSIMS (nanoscale secondary ion mass spectrometer), an instrument used to run very small-scale chemical analyses, they then observed the incorporation of oxygen-18 in the calcareous
'It seems more than probably' he continued, 'that the supremacy of Mount Everest itself, since we now know it to be in greater part of soluble calcareous
rocks, must be largely due to vertical uplift in the past that may be continuing at the present time.
leftovers of these samples, mainly small limestone nodules, were processed for conodonts.
Stony Point is composed of a wide range of calcareous
and non-calcareous rocks and concrete, which allows many substrate specialists to colonize the area.
The suitable criteria (Arain et al., 2014) for cotton cultivation was characterized by the factors: canal command area; soil pH (6.6-8.4); soil chemical properties classes (Acid soils: slightly acid, neutral soils: non-calcareous to slight calcareous
, mildly alkaline soils: non-calcareous to strongly calcareous
, moderately alkaline soils: non-calcareous to strongly calcareous
); mean maximum annual temperature (34 [degrees]C); soil physical properties classes (River plain and terraces: non-calcareous and calcareous
loamy soils); aridity classes (Arid (Kharif, Rabi) and Arid (Kharif), Hyper-arid (Rabi); agro-ecological zones (irrigated plains-D.G.
alga Lithothamnium calcareum is rich in calcium carbonate and magnesium, and it has some trace elements present in varying amounts, such as Fe, Mn, B, Ni, Cu, Zn, Mo, Se and Sr.
