• A survey of soils for aggregate stability and glomalin, a glycoprotein produced by hyphae of arbuscular mycorrhizal fungi.

• Compost-treated soils exhibited higher organic carbon content than inorganically fertilized soils, throughout the experimental period.

• Although the soils are inherently fertile, deep and with good drainage, they have been depleted of nutrients over the years.

• Aluminium contents showed great variability, with the largest amounts in soils from bare eroded plots.

• Cosmopolites sordidus density was greatest in the mulched plots which may have reflected increased longevity and/or longer tenure time in moist soils.

• Seedling emergence and yield of pearl millet on naturally crusted arid soils in relation to sowing and cultural methods.

• The movement of contaminants through soils is extremely limited unless significant amounts of water are available.

• Differences in geography, cultivars, rootstocks, soils, microclimate and growers' personal preferences determine the production practices and materials used in organic apple orchard management.
