Ongoing research is focused on depth monitoring as well.
The irrigation scheduling was based on soil moisture and rooting depth monitoring.
Besides, the tillage depth monitoring system can not only monitor tillage depth in real time, but also display a graphical trace of tillage history.
Hence, such a measuring system holds good potential for its application to the current tillage depth monitoring, particularly in the case of covered ground as in conservation farming.
This study also showed that soil water and root depth monitoring can be used in irrigation scheduling to avoid water stress.
Experimental results of aboveground biomass, nitrogen accumulation, N2 fixation and rooting depth monitored regularly during the crop cycle were compared to simulated results.
Herein, an adaptable tillage depth monitoring system, which is provided with a surface-fitting swing arm and an optical encoder to measure the rotation of the swing arm, has been designed and developed.
The improved size and power could make possible a handheld scanner that automatically penetrates to the desired depth, monitoring tumors or searching for anything suspicious.
First, existing geodetic GPS stations are expensive and thus expanding coverage to new sites, specifically for snow depth monitoring, is likely not the best fiscal approach.
According to the description in "ARIMA model," SARIMA ( (p, d, q) times (P, D, Q)^{s} ) is created using SPSS 18.0 software with the monthly average groundwater table depth monitored during 2000 2009.
