The plant hormone auxin is fundamental for plant growth, and its spatial distribution in plant tissues is critical for plant morphogenesis. We consider a leading model of the polar auxin flux, and study in full detail the stability of the possible equilibrium configurations. We show that the critical states of the auxin transport process are composed of basic building blocks, which are isolated...
the aim of this study was to determine the optimum mixture ratios for composting separated cattle manure and pepper plant residues. five 127 liter laboratory-scale bioreactor were used to investigate of separated dairy manure addition on the composting process of greenhouse pepper plant residues. cattle manure is considerably rich in nitrogen. however, composting with cattle manure alone is not...
