Root trainer Root trainer A root pruning container is an aid to the cultivation of young plants and trees in nurseries. Many pot designs train the roots. One example is a truncated plastic cone in which a seedling is planted. There is a drainage hole at the bottom and the main tap root tends to grow towards this. What this achieves is to encourage the roots the grow a denser system of root hairs. How it does this is to have the pots designed so as to air prune the roots. The advantage is when the plant is planted into its home
Root cause analysis the current investigator. Looking at the second example, a deeper level root cause is that the maintenance procedures at the plant included periodic inspection of the lubrication subsystem every two years, while the current lubrication subsystem vendor's product specified a 6-month period. Switching vendors may have been due to management's desire to save money, and a failure to consult with cognizant engineering staff on the implication of the change, and so on. Thus, while the "root cause" shown above may have prevented the quoted recurrence, it would not have prevented other perhaps more severe future failures. Quite often, "engineering-type" root
