Searching for artificial compost that could effectively enhance plant productivity while possessing high resistance in harsh soil conditions and a tunable pore size is of great importance towards the realization of long-lasting fertilizer. In this work, the artificial compost was modeled using porous polymer membrane pipes (PPMP) with a diameter of 5 mm and 7 1-mm-sized channels. Glass beads with a diameter of 10 mm and Glass Raschig rings (GRR) with a diameter of 7 mm and a 5-mm-sized channel were employed as a model of soil particles and normal compost, respectively. The hydrodynamics of the beds composed of various volumetric ratios of spherical and tubular particles were studied using a falling-head method. The results indicate that the addition of PPMP into the bed shows comparable bed porosity to the corresponding GRR bed. The beds with added PPMP particles demonstrate a five-fold higher water-holding capacity than that of GRR beds, with the same particle ratio. Slightly higher bed permeability were noticed in the beds composed of PPMP particles, which suggest improved water motion throughout the bed particles. The results reveal that artificial compost fabricated from polymer materials are potential in the preparation of highly durable fertilizer that can be applied in next generation agricultural technology.
