SEQUENTIAL INVESTMENT IN SITE-SPECIFIC CROP MANAGEMENT UNDER OUTPUT PRICE UNCERTAINTY [PDF]
An option-value model is developed to analyze the impacts of output price uncertainty, high sunk costs of adoption, and site-specific conditions on the optimal timing of adoption of two interrelated site-specific technologies, soil testing and variable ...

Soil Degradation Processes from Pollution
Chemistry Journal of Moldova, 2012 Investigations found HCH and DDT residuals in bottom sediments from several reservoirs and lakes as well as the main rivers, Nistru and Prut (concentrations ranged between 0.2 and 15.8 ppb). The concentration of PCBs in the topsoil collected beneath the capacitors battery at the Vulcănesti substation reached a level of 7100 ppm which is exceeding the ...
