Introduction Crops monitoring on large-scale farm is a complex and time-consuming exercise, particularly in warm arid conditions where crops can change drastically in 24 hours. Reducing scouting time is of great importance while providing maps for large areas within hours would be the ultimate goal. With multi-spectral sensors, biomass is monitored accurately helping the… read more »

Introduction Accurate soil water content measurements are critical for estimation of energy and water balances, as well as for understanding chemical and biological processes in vadose zone, plant root zones and in groundwater.[1] Soil electrical conductivity is an indirect measurement that correlates very well with several soil physical and chemical properties. Electrical conductivity is the… read more »

Introduction The EM38-MK2 sensor provides measurement of the ability of the soil to conduct electricity within two distinct depth ranges, without any requirement for soil-to-instrument contact. With a maximum effective depth of exploration of 1.5 m, applications in agriculture are perfect. An optional, collapsible calibration stand supports automation of the instrument calibration procedure. Once positioned… read more »
Introduction The EM38-MK2 provides measurement of both the quad-phase (conductivity) and in-phase (magnetic susceptibility) components within two distinct depth ranges, all simultaneously, without any requirement for soil-to-instrument contact. With a maximum effective depth of exploration of 1.5 m, applications in agriculture, archaeology and general soil sciences are common. The standard EM38-MK2 includes two receiver coils,… read more »

Scientific Article Development and field evaluation of a completely automatic system for intra-row weed control in tomato fields. This system uses an automatically generated GPS crop plant map to automatically control the path of a set of mechanical intra-row weed knives in order to kill weeds growing between tomato plants in the seedline. The… read more »
Scientific Article Researchers at UC Davis and elsewhere have demonstrated the technical feasibility of using RTK-GPS technology to automatically create crop plant maps at planting (Sun et al., 2010; Perez-Ruiz, 2011). This paper describes the development and field evaluation of a completely automatic system for intra-row weed control in tomato fields. This system uses… read more »
