In addition to their ability to alter chemical attributes, poultry litter and liquid swine slurry applications in agricultural lands can improve soil physical structure by acting on aggregate formation and stability, in particular via glomalin and extraradicular mycelium production. The aim of this study was to evaluate the effects of different rates of poultry and swine manure on microbiological (glomalin and extraradicular mycelium) and physical (aggregation) parameters and to establish a relationship between them. The experiment was conducted in a very clayey Oxisol, in a randomized block design with four replications. The design consisted of a 2 x 4 + 2 factorial scheme combining two types of manure, poultry and swine, at four rates corresponding to 67, 100, 133 and 200% of the amount of nitrogen (N) required for oat crops, as well as two control treatments, where, in one, no N was applied, and, in the second, urea was applied to provide the recommended N rate. After six years with semiannual applications, in no-tillage system, soil samples were collected within 0.00-0.10 and 0.10-0.20 m depths. Compared with applications of liquid swine slurry, chemical fertilizer or no fertilizer, application of poultry litter, mainly at the 133% N rate, stimulated the production of active and total extraradicular mycelium and total glomalin, and both increased and stabilized the soil aggregates within the 0.00-0.10 and 0.10-0.20 m soil layers. In both layers, the production of active and total extraradicular mycelium was positively correlated to the formation of aggregates of relatively large diameter (> 8.00 mm) and, consequently, to increases in the geometric and weighted mean diameter. The production of easily extractable and total glomalin was positively correlated with the aggregate stability index and the formation of aggregates with an intermediate diameter (between 1.00 and 8.00 mm). These results indicate that manure application can be used to maintain or improve soil aggregation in addition to chemical fertility, but this benefit depends on the type of the manure used.

除了改变化学属性的能力外，在农用土地上使用家禽垫料和猪液也可以通过影响骨料的形成和稳定性，特别是通过gloomalin和放射状菌丝体的生产来改善土壤的物理结构。这项研究的目的是评估不同比例的家禽和猪粪对微生物（球蛋白和放射状菌丝体）和物理（聚集）参数的影响，并建立它们之间的关系。实验是在非常黏稠的Oxisol中进行的，采用随机区组设计，重复四次。该设计由2 x 4 + 2因子分解方案组成，结合了两种类型的粪便，家禽和猪，四种速率分别对应于燕麦作物所需氮（N）的67％，100％，133％和200％，以及两种对照处理，一种是不施氮，第二种是施尿素以提供推荐的氮含量。每半年使用半年后，在免耕系统中，土壤样品的收集深度为0.00-0.10和0.10-0.20 m。与使用液态猪粪，化学肥料或不使用肥料相比，家禽凋落物的施用（主要以133％N的比率）刺激了活性和总放射状菌丝体和总胶质素的产生，并增加并稳定了土壤中的团聚体。 0.00-0.10和0.10-0.20 m的土层。在这两层中，活性和总根外菌丝体的产生与相对较大直径（> 8.00 mm）的聚集体的形成呈正相关，因此，增加几何和加权平均直径。易提取的总胶质瘤蛋白的产生与骨料稳定性指数和中间直径（1.00至8.00毫米）的骨料的形成呈正相关。这些结果表明，除了化学肥力外，施肥还可以用于维持或改善土壤的聚集，但是这种益处取决于所用肥料的类型。
