[Mapping method in the epidemiological study of infections and infestations. II. Soil characteristics in localities permanently at risk for anthrax].

Investigations carried out with the use of the mapping method have revealed that the distribution of localities with stationary unfavorable situation in anthrax throughout the area is linked with the agrochemical properties of soils. The number of the foci of anthrax on neutral and weakly alkaline soils has proved to be considerably higher than in soils with low pH values. No relationship between the content of humus in soils and the distribution of localities with stationary unfavorable situation in anthrax throughout the area has been detected. The results of investigations carried out with the use of the mapping method permit experts to make forecasts and to examine the ecological aspects of the projects carried out in the area.
