The use of resource management technologies such as zero tillage, which can affect the soil properties, can restore soil health that is degrading at a rapid pace due to intensive agriculture, inefficient and imbalanced use of fertilisers, high-yielding crops, the use of heavy machinery, excessive tillage, etc. The health of the soil can be measured by the capacity of microorganisms that can act as early warning signals. To improve soil quality, zero tillage is recommended globally and has significant effects on soil microbial communities.

The study has designed a process to record dozing-off event, then constructed and implemented the hypnogram processing program that evaluated quantitative changes in polysomnography signals at sleep onset, the transition time from wake stage to sleep stage. By analyzing the energy spectrum of the signal and using wavelet transform in combine with the support vector machine algorithm, the research allows a comprehensive evaluation of the state of dozing-off. Determining the exact time of onset of sleep is very important in the study of drowsiness.
