Rillig, M. C. 2004. Arbuscular mycorrhizae, glomalin, and soil aggregation. Can. J. Soil Sci. 84: 355–363. Arbuscular mycorrhizae are important factors of soil quality through their effects on host plant physiology, soil ecological interactions, and their contributions to maintaining soil structure. The symbiosis is faced with numerous challenges in agroecosystems; in order to inform sustainabl...

Objective: To study plants purification capability of  Cu on two cultivars of vetch plant (Vigna Radiata) in contaminated soils and their effects on morphological characteristics. Methods: we conducted a completely randomized trial as factorial. Different concentrations of  Cu (0, 150, 300, and 400 mg/ Kg of dried soil) were used. After four weeks growth on contaminated soil, parameters such as...

Reduced tillage methods for field crop production result in less disruption of soil structure and often increased amounts of crop residue maintained on the soil surface. The combination of these two factors produces increased surface soil aggregation. This study was conducted in the field and within pots to determine whether surface residue by itself improves soil aggregation within a short per...
