In 1907, the boll weevil crossed the Mississippi River, but the rich alluvial soil
gave the Delta cotton some resistance.
The nest was then inspected and contained 23 eggs buried > 60 mm below the ground surface in moist alluvial soil
, in a flask-shaped chamber 150 mm deep by 120 mm wide (Fig.
Quaternary red clay soils have higher clay content than calcareous alluvial soils
(Table 1), and this might be expected to inhibit OC decomposition during incubation and result in less C[O.sub.2] being emitted from the high-clay content soil (Sotta et al.
'Typically, alluvial soils
are more fertile and retain more moisture than hillsides.
The choice of these soils is for their big differences in the chemical and mineralogical properties, mainly in texture (% clay = 56.3 for alluvial soil
and 11.7 for calcareous soil) and specific surface area (233.8 [m.sup.2]/g for alluvial and 87.6 [m.sup.2]/g for calcareous soil), as shown in Table 1.
These come from sites on the upper slopes of tumbling valleys to the alluvial soil
of an oxbow created long ago on an ancient river.
The farmland is level or gently undulating with fertile alluvial soil
Caney Creek, with red, rich alluvial soil
along its watershed, also runs through Wharton on its way to Sergeant at the Gulf and the San Bernard River is not that far away, not to mention Peach Creek which also passes through the county just north of Wharton.
Nearing--with help from Zhang and Akitsu Kimoto, who is doing postdoctoral work funded by Japan--is studying the oxides' performance in watersheds in the semiarid American Southwest's alluvial soil
near Tombstone, Arizona.
This indicates that the modification for the value of N is generally underestimated because alluvial soil
contains a relatively higher proportion of fine content.
A new McKenzie-Willamette Medical Center south of the Willamette River and near downtown seems a good idea to me, but not on the Eugene Water & Electric Board's narrow strip of alluvial soil
between the railroad tracks and the river.
The alluvial soil
of the Po Valley in southwest Lombardy produces superb rice that is served up daily in the form of risotto and other classic dishes.
