Abstract: Farmland tillage is an important link in crop production, and the quality of operation directly affects crop yield. Soil tillage is also a process that occupies a large proportion of energy in the whole production process, and its operation process is actually a process to overcome soil mechanical resistance. Scientific use of tillage energy can significantly improve planting efficiency. Accurate and realtime measurement of tillage load is the prerequisite for realizing accurate operation control. This paper enumerated the commonly used load test methods at home and abroad, analyzed their advantages and disadvantages, introduced several new measurement methods, and studied the research process of test system development and prediction model at home and abroad, summarized the tillage load test methods in China, pointed out the lack of special sensors, research on tillage resistance model and the backward test program, and finally given development suggestions: research on the application of multidimensional force sensors in test methods, research on small size, large range and high strength sensing elements, strengthening the research of tillage resistance prediction model, strengthening the research and development of load invariant transfer structure.

Key words: tillage load, agricultural sensor, energy saving, predictive models, precision agriculture
