Plant interfaces

It has been found that many environmental factors influence the amount and composition of root exudates and hence the activity of rhizosphere microbial populations. Microbial composition and species richness at the soil-plant interface are related either directly or indirectly to root exudates and thus vary according to the same environmental factors that influence exudation. In es.sence, the rhizosphere can be regarded as the interaction between soil, plants and microorganisms. Figure 2 shows some of the factors associated with these interactions, which will be discussed during the course of the chapter. Here we mention briefly the influence of some plant and microbial factors on root exudation and rhizosphere microbial populations, while soil factors are discussed later.

Each TRBP has an inner vessel and an outer box. The outer box provides the heat source, the physical support structure, and the platform for connecting to utilities and other plant interfaces. Materials to be treated are placed in the inner vessel.

Field instrumentation design is a more self-contained and standardized activity, aside from the physical plant interface, which we discussed in the previous chapter. The input information from P I diagrams and individual instrument data sheets requires little interaction other than the need to challenge whether the accuracies and specified details are really necessary, considering the costs and other consequences of which the specifying process engineer may not be aware.

II is important to appreciate that such acceptance testing of lumlcey systems is only part, albeit a major part, of the commissioning process which embraces functional checks on the whole system, including field instnimeniaiion, plant interfaces, operator interfaces and support systems. This chapter concentrates on the post-acceptance, site-based phase of commissioning. 

The speciation of certain elements in water is important, as it throws light on the transport of the elements between other media, e.g. the soil-plant interface. In this context, atomic spectrometry has the role of providing a sensitive and virtually specific detector for the individual elements, after some... 

The only signals which cross this test boundary are the signals to and from the plant. Thus at this level of testing it would be appropriate to introduce plant simulation to generate consistent sets of signals. However, simple switch and lamp test rigs could also be used to drive the PES-Plant interfaces.
