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 Remote Sensing is the ability to measure the properties of an object or region without the need of physical contact with the object itself (Lillesand and Keifer, 1994). In most remote sensing applications, electromagnetic radiation (EMR) is used to ‘sense’ a certain attribute of the object or area of interest.[1] By combining more than… read more »

Introduction An unmanned aerial vehicle (UAV), commonly known as a “drone” is an aircraft without a human pilot aboard. The flight of UAVs may be controlled either autonomously by on-board computers or remote control pilot on the ground from distance. Agriculture is one of the main sectors that drones have find numerous uses and have… 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 »
