The aim of restoration is recompose a new vegetation structure in order to obtain benefits such as the containment of bank erosion, reestablishment of a hydric and nutrient regime, and increase the diversity of species. The present paper evaluated the development of the vegetation introduced as ciliar forest around a mining lagoon through establishing indicators based on the vegetation structure, physic-chemical characteristics of the soil and the water. Results show that the indicators of vegetation, like dying of species and the covering of top were classified as negative factors. Regarding vegetation development, it was considered positive when individuals out of inundation points were analyzed. According to soil indicators, chemical factor pH acid suggests intoxication by aluminum, iron and manganese impeding development of the vegetation in the local. Topographic factor also caused erosion and dying/extinction of species localized in declining points and carried nutrients to the inundation point and finally to the sand mining pool.

Excavations at Hengistbury Head Site 6 (Dragonfly Ponds) in 1984–5 uncovered a rare sequence of cultivation features, with pre-Late Iron Age to Romano-British period spade marks and an associated cultivation soil underlying proposed Romano-British furrows and another cultivation soil (Chadburn & Gardiner 1985; Chadburn 1987). Keyhole excavations for soil micromorphological study of these features and soils were conducted in 1997 as part of a larger project on identifying and characterising prehistoric cultivation from soil indicators in the field and in thin section (Lewis 1998). Profile inversion indicators identified within the implement marks suggest that the spade-mark horizon may show ‘double-digging’, and that the furrows were probably created by post-Roman mouldboard ploughing. Excavation and soil micromorphology results are presented here, and the importance of the remains at Hengistbury Head to the study of ancient agricultural land use is discussed in terms of methodological issues.

'Soil health' programs and projects in Australia's agricultural districts are designed to influence farmers' management behaviours, usually to produce better outcomes for production, conservation, and sustainability. These programs usually examine soil management practices from a soil science perspective, but how soils are understood by farmers, and how that understanding informs their farm management decisions, is poorly documented. The research presented in this paper sought to better understand how dryland farmers in the Billabong catchment of southern New South Wales use soil indicators to inform their management decisions. Thematic content analysis of transcripts of semi-structured, face-to-face interviews with farmers suggest several themes that have implications for soil scientists and other professionals wishing to promote soil health in the dryland farming regions of south-eastern Australia. In particular, all soil indicators, including those related to soil 'health', need to relate to some clear, practical use to farmers if they are to be used in farm decision making. This research highlights a reliance of the participants of this research on agronomists. Reliance on agronomists for soil management decisions may result in increasing loss of connectivity between farmers and their land. If this reflects a wider trend, soil health projects may need to consider where best to direct their capacity-building activities, and/or how to re-empower individual farmers.
