Abstract: During evaluation of physical and chemical properties of sandy soils and their fertility in Southern part of Republic of Chad it has been revealed that some soils have very high content of strontium. Its content varies from 10 to 270 mg/kg of soil depending on type of soil, depth of soil layers, clay and organic content. Strontium content negatively correlates with total content of calcium and phosphorus in layers of soil. Low CEC (CEC - Cation-exchange capacity) of soil may be a reason of possible translocation of strontium from higher to lower layers of soils. Strontium content in soils do not relates with level of radioactivity of soil measured. The highest content of strontium has been found in soils developed on some eolian and colluvio-alluvium deposits. Some researchers hypothesize that some endemic and chronic diseases such as Kashin-Beck disease, `Dysostosis enchondralis endemic`, endemic hoiter, osteoarthritis might be caused by high content of strontium in water and plant foods contaminated with it. Absence of consensus on etiological factors of these diseases confirms that it is worth considering necessity of further studies of different affects of high content of strontium in water and foods on human health directly or indirectly through causing misbalance in mineral nutrition
