Question

Second, soil structure results from a complex relationship between organic matter and the mineral matrix, with a degree of physical protection from decomposition of SOM often being conferred by its adsorption onto mineral surfaces. SOM contains nutrients that, when decomposed by micro-organisms (mineralized), are transformed into mineral forms that are available to plants. However, the physical protection of SOM can cause the supply of N to plants to be smaller from clay soils, which protect SOM, than from sandy soils containing identical amounts of SOM . In addition, the very structure of the compounds mineralized confers a degree of protection by prevent- ing decomposer organisms or their exoenzymes from accessing the nutrients in them. Certainly, some soil carbon, and by association probably some soil N, is centuries old .

Answer 1

其次，有机物和矿物质之间的复杂的关系决定了土壤的结构，矿物的表面吸附物常常在一定程度上给予土壤有机质的分解以物理保护，土壤有机质中含有的养分在微生物进行分解时，能被转化为矿物的形式提供给给植物，然而，对土壤有机质的物理保护可能导致粘土中N对植物的供应少于土壤有机质含量水平相同得沙土。此外，这种化合物的特殊的矿化结构在一定程度上预防了有机物分解和由于有机物分解而导致的养分混合。当然，一些土壤中得碳，可能还有一些氮，已经存在了上百年。

第二,土壤结构,结果从复杂的关系和矿物矩阵的有机物质,带有一定程度的身体保护的分解,它常被授予分别在矿物表面的吸附量。SOM含有养分,当为(矿)、微生物转化为矿物形式,是可得到的植物。然而,物理保护SOM能导致供应,对植物比较小,从粘土及保护比砂土的含有相同。此外,该化合物的结构矿一定程度的保护原有的ing decomposer有机体或预防——他们的exoenzymes接触到营养。当然,有些土壤碳、氮,也许有些土壤协会是百年的历史。

Answer 3

第二,土壤结构的分析结果是从矿物矩阵和有机物质的复杂关系中得来,通过分解SOM所赋予它的矿物表面吸附而带有一定程度的物理上的保护。当SOM被微生物转化为可被植物吸收的矿物形式时它便成为了养分。然而,SOM的物理保护会导致氮的供应相对于沙土来说比较少,而沙土含有相同量的SOM。此外,该化合物的结构的矿化通过防止分解生物体或其exoenzymes得到养分得到了一定程度的保护。当然,有些土壤，氮也许会有上百年的历史。

无奈啊，太专业了，能力有限，手工的。。心意到了。。

The
nonstop

It
takes

We
will
try
our

to
get
the

which
is
ETD:12-31,

,我确定定单,觉用set
an
order表示比较礼貌.
我今拿定单,otherwise表示相反情况,须再罗嗦遍.
