Researches Regarding the Electro-Conductivity Determination on Different Soil Textures from Romania, Before Sowing

Abstract. Precision farming involves the collection of detailed information about the characteristics of agricultural operations. Electro-conductivity (EC) of soil is one of the tests easier and less costly for agriculture, which can be performed today. Electro-conductivity (EC) is the ability of a material to transmit (conduct) an electrical current and is usually expressed in miliSiemens / meter (MS / m). Electro-conductivity (EC) of soil is a measurand that characterizes many soil properties which affect the productivity of crops. These include the water content, soil texture, soil organic matter (OM), depth to clay layer, the capacity of cation exchange (CEC), salinity, calcium, magnesium. Measurements of electro-conductivity (EC) of soil can add value to agricultural operations if they can be used to help explain variations in agricultural production. Article shows electro-conductivity maps models of the prepared soil in different locations in Romania and electro-conductivity correlation with the physico-chemical properties of these soils
