A treatment with lime would be introduced to determine the well potential of a soil. The lime can be used to reduce swell. For an expansive soil, A more or less degree of expansive soil may be present activities of the clay minerals. Once, the lime needs to be added that requires a minimum amount of the lime, it can reduce swell to acceptable limits. There is an experimental process for conducing swell test which can be found in ASTM D 1883. The depth of lime should be incorporated into the soil, in general, the equipment used by the construction of a limited. In general, A maximum required depth need to be calculated with 2 to 3 feet that can be treated directly without removal of the soil.
The International Union of Soil Sciences ( IUSS ) has thus far presented the Distinguished Service Medal to two prominent world citizens and policy makers. The first medal was awarded to HRH the late King of Thailand Bhumibol Adulyadej in 2012. The second medal was presented to HE Hon’ble Stéphan Le Foll for promoting soil science on the global agenda through COP21, and making soil and agriculture integral solutions to climate change and advancing food security. By so doing, HE Mr. Stéphane Le Foll effectively translated the scientific information of soil science into a global action programme. By implementing the “4 per Thousand” programme, Mr. Le Foll has enhanced the awareness of the importance of soil and its management for addressing the global issues of the 21st century. IUSS shall be pleased to work with him and the other members of the scientific team involved in implementing the “4 per Thousand” Initiative and support it globally.
