Abstract
The principles of Process Intensification and Miniaturization technology,
originally developed for chemicals processing, biotechnology and tissue
engineering were applied to achieve plant growth and crop yield enhancement,
which can be described as AgroProcess Intensification (A-PI). The basic
principle of A-PI is the enhancement of multiple interactions between plant
roots, water, nutrients, bacteria using micro-(bio)reactors as synthetic
rhizosphere in soil (SRS) which is a highly porous nano-structured hydrophilic
ionic macro-porous polymer. If soil fertility is not limited by water, nutrients or
bacteria then these soil additives do not have any function, although they can still
be used as root delivery system for plant protection. In this study, we used
nutrient and bacterium depleted soil with or without water stress to grow
soybean in order to demonstrate the effect of the SRS in enhancing biomass
growth under stress. Through an extensive scanning electron microscopy
studies, it is shown that AgroProcess Intensification is achieved through the
association of the plant roots with SRS which retains both soil water and
nutrients and transfer them to the plant while protecting the nitrogen fixing
bacterium. Implications of this method are discussed in terms of engineering of
ecosystem to grow crops and biomass in substandard soil under water and
fertilizer stress.
