[Prediction of the time of development and survival of ascarid eggs in the soil in the Kursk Region].

The paper shows that the currently available methods used to predict the time of development and survival of ascarid eggs in the soil, by analyzing its temperature and moisture (bioclimatograms and nomograms), provide no precise information. At the same time soil chemical and man-made pollution by heavy metals and the presence of geomagnetic fields are disregarded. Improved bioclimatographic and nomographic methods are proposed, with the correction factors being kept in mind.
