Sugar beet is an economically important crop grown on around 30,000 ha in the province of Skane in the south of Sweden. This project examined the effects of lime on soil factors and yield response in sugar beet in 52 soils in Skane. Previous research

Bentonites are candidate materials for the encapsulation of radioactive waste. In the ‘Alternative Buffer Material test’ (ABM), compacted ring-shaped blocks of eleven different buffer materials (mainly bentonites) were packed vertically on top of

Bentonites are candidate materials for encapsulation of radioactive waste. The cation exchange capacity (CEC) has proven to be one of the most sensitive parameters for detecting changes in mineral properties in bentonite-alteration experiments. An in

Damping off and chronic root rot of sugar beet caused by Aphanomyces cochlioides is a major constraint in cultivation of sugar beet, with occurrence of the disease in Sweden being concentrated to specific areas. This study examined soil factors that

The Long Term Test of Buffer Material (LOT) project at the Aspo Hard Rock Laboratory, Sweden, is a series of medium-scale field experiments focused on validating models and hypotheses concerning long term processes in the bentonite buffer of a reposi

The increasing focus on the chronology of environmental and climatic changes of the last glacial-interglacial transition has led to several independent attempts to try to calibrate the 14C time-scale beyond the Holocene. The Late Weichselian Gotiglac

A study of past lake-level changes in Lake Xinias covering the last 40 000 years was presented in an earlier paper. In that paper, changes during the Holocene were only briefly dealt with, because of poor sedimentary representation. In this paper a s

The estimated quantity of cement for construction and sealing purposes is around 9E5 kg in the planned Swedish KBS3 repository for nuclear waste. The highly alkaline cement pore fluid (pH > 12) may affect other components in the repository, and espec

Soils showing suppressiveness to Aphanomyces root rot of pea in bioassays and field experiments were surveyed in an area intensively cultivated with vining pea in southern Sweden. By examining the relationships between disease suppression, soil miner

The investigation of Lake Xinias, Greece, deals with lake-level changes since about 40 000 B.P. Particular effort was made to obtain a reconstruction of lake level during the Last Glacial Maximum, at about 18 000 B.P. The reconstruction was based on
