Impact of volume scattering from tilled soil using a 2D numerical model

The soil tillage is the last work before sowing and has a large effect on plant emergence [1]. Thus, tilled soils should be properly prepared along the whole field unless the impact of spatial heterogeneous property of the soil. One of the main characteristics of tilled soils is the size of the generated clods lying in fine earth. The main goal of this study is then, to estimate the clods` size thanks to a measurement of the scattered electromagnetic waves created by their interactions in the microwave domain. To fulfil this goal, a numerical approach is led by resolving the Maxwell`s equations in time domain with finite element method.
