Abstract

In addition to yield mapping in combines and in other harvesters, biomass distribution in growing plant populations is a possible parameter for surveying heterogeneity inside of fields. To develop the technique of acquisition of biomass data by mechanical scanning of plants with stems, it has been shown that definite, simple relationships between dynamic effect and biomass arise through strip scanning of plant populations. When a cylindrical body and a pendulous pivoted cylindrical body are moved horizontally through a plant population, the forces acting on the cylindrical body and also the angle of deviation are determined by the parameters of plant growth, mainly biomass. By measuring the forces on the cylindrical body and the angle of pendulum, conclusions can be drawn about the biomass of crops. With measurements are determined differences in still growing crops in order to optimise crop management and yields in Precision Agriculture.
