APPLICATIONS OF ELECTRICAL AND ELECTROMAGNETIC GEOPHYSICAL METHODS IN AGRICULTURE Dra. Claudia M. Sainato Head Professor. Chair of Physics. Department of agricultural engineering and land use. School of Agriculture. University of Buenos Aires csainato@agro.uba.ar Past research indicates a wide range of uses of electrical and electromagnetic methods in agriculture. Beyond the very well known environmental and groundwater applications, also related to agricultural activity, specific soil research has been done during the last years: soil salinity assesment, delineation of spatial changes in soil properties, soil nutrient monitoring from manure applications, among others. One of the last investigations in this field are the applications of apparent soil electrical conductivity in precision agriculture which enhances specific site management and yield mapping in order to plan the distribution of fertilizers, herbicides, pesticides. The main target then is to relate apparent electrical conductivity to soil properties, to evaluate the use of geophysical methods to make correct agricultural decisions. The aim of this talk is to make an overview of applications of these geophysical methods and probable future trends for agricultural geophysics. |
