Volcanoes create and shape landscapes. Soils in regions impacted by volcanic activity contain a memory of the eruptions that have occurred. Volcanic eruptive materials range from the iron-rich basaltic scoria and lavas, through layers of lava and tephra (volcanic ash) on andesite volcanoes, to silica-rich pumice from huge rhyolite eruptions.

Water is vital to life on Earth and is essential to soils and soil organisms. Water erodes soil and deposits material from which new soils form. Water is key to many physical and chemical weathering processes that convert rock materials to productive soil. The amount of water a soil can hold, and make available to plants, influences the kinds of plants

Soil-Borne Microbiome: Linking Diversity to Function
Microbial Ecology, 2015Soil microorganisms are sensitive to environment disturbances, and such alterations have consequences on microbial diversity and functions. Our hypothesis is that alpha diversity of microbial communities and functional diversity decrease from undisturbed to disturbed soils, with consequences for functional redundancy in the soil ecosystem. To test this

Soil-Borne Pathogens and Their Interactions with the Soil Environment
2010Wheat yields in thirteenth century Europe have been estimated at 385 kg ha−1 (Pretty 1990; Houghton 1996), more than half a millennium later, by 1939 they had been increased to little more than 2 t ha−1. Subsequently, in the period 1952–1986 scientific and technologically based innovation applied to farming increased yields by an average value of 2.6 ...

The transfer of man-made radioactive materials from soil to man through the food chain by the intake of vegetables, fruits, meats, and milk continues for a long time. In a UN Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) report (1), the transfer coefficient from fallout radionuclide deposition to diet was precisely described ...

A virus is soil-borne if it infects plants via soil. This may occur either through the activity of a soil-borne vector or by mechanical means, and usually this implies virus transmission to the underground parts of plants. However, if leaves or other aerial parts were infected following contact with soil (2), this would also be included.

Monoclonal antibodies to beet soil‐borne virus
Annals of Applied Biology, 1992SummaryFour monoclonal antibodies (MCA) were obtained to the ‘Ahlum’ serotype of beet soil‐borne virus (BSBV). On ELISA plates which had been precoated with polyclonal antibodies (PCA) all four MCA detected this serotype with a higher sensitivity than alkaline phosphatase‐labelled PCA.

EFFECTS OF INNOVATIVE FILMS IN SOIL SOLARIZATION FOR THE CONTROL OF SOIL-BORNE PATHOGENS
Acta Horticulturae, 2003The effectiveness of soil solarization during autumn was evaluated in Sicily (36°48’N, 14°36’E) in a multi-span tunnel greenhouse through the survival of two soil-borne pathogens Fusarium oxysporum f. sp. radicis-lycopersici (FORL) and Cylindrocladium pauciramosum.

Fertilizers and soil‐borne diseases
Soil Use and Management, 1990Abstract. Nutrient manipulation through fertilization or modification of the soil environment to influence nutrient availability is an important cultural control for plant disease and an integral component of production agriculture.

The Ecology of Soil‐borne Pathogens
EPPO Bulletin, 1972AbstractThe complexity of the interrelations of the varying environmental factors which may affect the host, the pathogen and consequently the host‐pathogen inter‐ action is stressed. The effect of climatic conditions, soil properties, soil biota and human influences is indicated. Two aspects of the ecology of soil‐borne pathogens, viz.
