在蒙特利尔、魁北克和圣约翰湖的农业区取样了富含粘土的土壤。在st - rosalie、Kamouraska和Normandin土壤系列中，未破坏的土块和大块样品采用水平采集。团聚体稳定性随有机质含量的增加而增加。总体而言，B层的容重最高。孔隙度占土壤总体积的39% ~ 56%，最具代表性的孔径为0.706 ~ 0.048 μm，其中Ap层孔径最大。st - rosalie土的大、中、小孔隙的孔隙度分布与Kamouraska和Normandin土不同。在前者中，中等孔隙只占总孔隙率的百分之几，而在后者中，孔隙分布更为均匀。随着粘土含量的增加，中孔含量降低，小孔含量增加。孔隙大小与粘土含量之间无显著关系。导电性，与…
Clay-rich soils were sampled in the agricultural areas of Montreal, Quebec and Lake St-Jean. Undisrupted soil blocks and bulk samples were taken by horizon in the Ste-Rosalie, Kamouraska and Normandin soil series. Aggregate stability increased with the organic matter content. Bulk density was generally highest in the B horizons. Porosity ranged from 39 to 56% of the total soil volume and the most representative pore diameter varied from 0.706 to 0.048 μm with the largest diameter being found in the Ap horizons. The distribution of porosity among large, medium and small pores in the Ste-Rosalie soil differed from that in the Kamouraska and Normandin soils. In the former, medium pores accounted for only a few percent of total porosity, while the pores were more evenly distributed in the latter soils. Medium pore contents decreased, while small pore contents increased, with increasing clay contents. No significant relationship was observed between large pores and clay percentages. Hydraulic conductivity, wit...
