A detailed investigation into the accuracy of seed delivery by a seeding equipment necessitates a method for measuring the seeding uniformity of seeds after release from the metering mechanism. An electronic detector is described which detects accurately (±1%) a broad range of seeds. Operation is simple and requires no external sensitivity control. During application the coefficient of variation, misses and doubles/multiples in a sample run can be obtained continuously under static or dynamic situations. The method enables a reliable sample to be obtained and the results can be rapidly analyzed.
Precision planting is necessary in order to improve and promote mechanical weed control, and thereby reduce environmental contamination caused by herbicides.
