In-filed dynamic methods for soil physical characterization

Abstract

The main objective of the presented researches is to develop in-field dynamic methods for soil characterization. Two technologies are developed: the first one is an electromagnetic method, based on the use of a microwave radar; the second one is mechanical, with the measurement of the soil mechanical resistance (steel blades plough the soil at different working depths). These sensors are implemented on mobile engines. Combined with a global positioning system (GPS), they allow to create in-field maps of soil's heterogeneities.
