In both cases, Mg was found to be mostly present as periclase (MgO) and also partially bound as undecomposed
carbonates (dolomite--CaMg[(C[O.sub.3]).sub.2] can be found in the CFBC bottom ash) or silicates (merwinite, [Ca.sub.3]Mg[(Si[O.sub.4]).sub.2], melilite, [(Ca,Na).sub.2](Mg,Al)[(Si,Al).sub.3][O.sub.7]).
The fresh field-moist soil sample was processed by passing it through a 4-mm sieve and removing from the soil all gravels >2 mm in size and large plant roots and undecomposed
Thatch is defined as the layer of partially decomposed or undecomposed
organic matter formed above the soil surface.
Raw Bone Meal--The dried, ground product suitable for animal feeding obtained by cooking undecomposed
bone in water at just enough atmospheric pressure to remove excess fat and meat.
The dominant plants acidify the soil, and the high content of phenolics, lignin, and waxes in their litter results in the accumulation of undecomposed
The soil-surface contribution to reflectance of vegetation cover varies with such factors as the amount of soil exposed, surface-moisture content, organic matter content (decomposed and undecomposed
), particle size distribution, soil mineralogy, soil structure, surface roughness, and shadow.
plant debris were removed from the soil surface, and the soil samples were sieved to pass through a 2-mm mesh.
[I.sup.(phi)] Cyclic multifunctional initiator with [phi] undecomposed
Residual fraction is mainly composed of quartz, K-feldspar, and minor undecomposed
calcite in PF ashes, and also additionally dehydroxylated clay minerals, calcite and traces of dolomite in CFB ashes.
On the FP plots, before doing this, the large undecomposed
fronds were temporarily removed, leaving only the partially and fully decomposed litter layer.
Thatch The accumulation of undecomposed
or partially decomposed organic material located above the soil surface.
